DETAILED DESCRIPTION
[0018] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
[0019] Various embodiments are directed to carpet products having an edge strip secured along edges of the carpet product to impede fraying of the edge of the carpet product, and to increase the dimensional stability of the carpet product. Moreover, various embodiments are directed to aircraft carpet kits comprising a plurality of carpet components having an edge strip secured along edges of the carpet product.
[0020]
[0021] Referring again to
[0022] Moreover, the edge portion may have an at least substantially flat exterior edge (e.g., facing away from the carpet product), thereby providing an at least substantially flat edge for the carpet product 1. The flat exterior edge may be at least substantially perpendicular to the base portion, such that the flat exterior edge may extend at least substantially vertically when the carpet product 1 is placed on a horizontal support surface. Accordingly, the flat exterior edge of adjacent carpet products 1 (e.g., adjacent carpet tiles) may be abutted in an installation to provide an at least substantially gapless joint therebetween such that no gaps exist between portions of the edges of the adjacent carpet products 1 as shown in the example of
[0023] With reference to
[0024]
[0025] As illustrated in
[0026] In various embodiments, the edge forming die 12 may comprise an aluminum and/or steel material having a non-stick coating (e.g., a nickel coating) such that the edge strip material is prevented from adhering to the edge forming die 12 while the edge strip material cures to form the edge strip 4 during the application process, although however, other materials could be used for the edge forming die 12. As illustrated in
[0027] Although not shown, the edge forming die 12 may be associated with a cooling mechanism configured to cool the edge forming die 12 to decrease the amount of time necessary to cure the edge strip 4. In various embodiments, the edge forming die 12 may comprise a cooling channel along a base portion of the edge forming die 12. The cooling channel may be configured to accept a cooling fluid (e.g., air, water, and/or the like) running along the cooling channel to cool the edge forming die 12 while the edge strip material cures against the carpet product 1. For example, the cooling channel may be configured to receive cooling air supplied by a vortex chiller.
[0028] In various embodiments, the edge forming die 12 may be at least approximately 6 feet wide, and accordingly the support surface 11 and the clamp bar 13 may have a corresponding width such that the carpet product 1 may be secured therein. However, any of a variety of widths may be utilized such as the non-limiting examples of a 15-feet wide edge forming die 12, clamp bar 13, and support surface 11; a 30-feet wide edge forming die 12, clamp bar 13, and support surface 11; and/or the like.
[0029] The clamp bar 13 is configured to move vertically between an open configuration (e.g., as shown in
[0030] In various embodiments, each of the edge forming bar 12 and the clamp bar 13 may be movable via one or more linear actuators (e.g., pneumatic actuators, hydraulic actuators, and/or the like).
[0031] The dispenser 14 may comprise a nozzle through which liquid edge strip material is applied onto the horizontal support surface of the edge forming bar 12. For example, the nozzle may have a 0.19″ diameter round application port through which the edge strip material is applied in liquid form onto the horizontal support surface of the edge forming bar 12. However, any of a variety of shapes and/or size extrusion ports may be utilized, including ¼″ diameter round application port, a rectangular application port, an oblong application port, and/or the like. In various embodiments, the dispenser 14 may be connected with an edge strip material supply, such as a heating pot configured to maintain the edge strip material supply in a liquid form. For example, the edge strip material supply may be configured to maintain the edge strip material at 350 degrees Fahrenheit.
[0032] The dispenser 14 may comprise one or more sensors configured to detect the positioning of the carpet product 1 placed within the edging apparatus 10. For example, the dispenser 14 may comprise one or more optical sensors configured to detect lateral edges of the carpet product 1 placed within the edging apparatus 10. Accordingly, the dispenser 14 may be positioned to apply edge strip material along the horizontal application surface of the edge forming die 12 at a position such that the resulting edge strip 4 does not extend substantially beyond the lateral edges of the carpet product 1.
[0033] In various embodiments, the edging apparatus 10 may comprise a plurality of dispensers 14. For example, a first dispenser 14 may be configured to apply edge strip material along a first portion of the length of the edge forming die 12, and a second dispenser 14 may be configured to apply edge strip material along a second portion of the edge forming die 12. Accordingly, particularly for long edge forming dies 12 in which the amount of time elapsed for the dispenser 14 to apply edge strip material along the length of the edge forming die 12 is sufficiently long that a portion of the edge strip material begins to cure before the edge forming die 12 is moved to the application configuration, two or more dispensers 14 may be provided to apply edge strip material to a portion of the edge forming die 12. Moreover, in various embodiments, the edge forming die 12 may be heated in order to slow the amount of time to cure the edge strip material. In such embodiments, the edge forming die 12 may be subsequently cooled to cure the edge strip material to form the edge strip 4 once the edge forming die 12 is in the application position.
[0034] Although not shown in
[0035]
[0036] Once the edge forming die 12 is positioned below the travel path of the dispenser 14, the dispenser 14 moves laterally across the width of the edge forming die 12, detects the position of the carpet product 1 (e.g., the lateral position of the carpet product 1 within the edging apparatus 10), and applies liquefied edge strip material onto the horizontal applicator surface of the edge forming die 12, proximate the notch of the edge forming die 12.
[0037] Once the bead of liquefied edge strip material is applied to the edge forming die 12 and the dispenser 14 is moved clear of the travel path of the edge forming die 12 (e.g., the travel path between the application configuration and the material receiving configuration), the edge forming die 12 is raised such that the horizontal applicator surface is adjacent the support surface 11, and the edge forming die 12 is moved laterally toward the support surface 11 to an application configuration (as shown in
[0038] Although the described process is illustrated and described with reference to an at least substantially linear edge of a carpet product 1, the described process may be configured apply edge strip 4 to any of a variety of edge shapes (e.g., curves, interior corners, exterior corners, and/or the like). In such embodiments, the edge forming die 12 may have a shape corresponding to the desired shape of the edge to be applied to the carpet product 1. For example, the edge forming die 12 may have a curved shape in order to provide a curved edge of a carpet product 1, an interior corner shape in order to provide an interior corner shaped edge of a carpet product 1, an exterior corner shape in order to provide an exterior corner shaped edge of a carpet product 1, and/or the like. In addition, a number of edge forming dies may be placed adjacent to each other, such as to create a corner shape from two straight edge forming dies.
[0039] Once the edge forming die 12 is positioned in the application configuration, the edge strip material cures while the edge forming die 12 remains in the application configuration. As described herein, the edge forming die 12 may comprise an integrated cooling mechanism, and accordingly the cooling mechanism may be configured to cool the edge forming die 12 and the edge strip material positioned on the edge forming die 12 to form the edge strip 4. Once the edge strip material cures, the clamp bar 13 is raised, such that the carpet product 1 may be removed from the edging apparatus 10. Moreover, in various embodiments, after the edge strip material cures, portions of the edge strip 4 extending beyond the lateral edges of the carpet product 1 may be trimmed (e.g., automatically and/or manually).
[0040] In various embodiments, the process described herein and illustrated in
[0041] Elongated carpet product 1 edges having a length longer than the width of the edge forming die 12 may be formed in a plurality of parts. For example, a first portion of the edge of the elongated carpet product 1 may be formed according to the method described herein. The elongated carpet product 1 may then be moved laterally to form an edge along a second portion of the same edge of the elongated carpet product 1. In such embodiments, at least a portion of the elongated carpet product 1 may extend beyond the width of the edge forming die 12.
[0042] In various embodiments, the above described process may be provided to form one or more carpet products 1 to be utilized to carpet the interior of an aircraft as a portion of an aircraft carpet kit 100, as discussed herein. For example, a first carpet product 1 may be provided having a shape configured to be positioned within an aisle of a commercial aircraft, between two or more floor lighting strips secured to a floor of an aircraft. In such an example, the edges of the carpet product 1 configured to be adjacent side edges of the floor lighting strips may comprise edge strip 4 forming an edge of the carpet product 1 as described herein. As yet another example, edges of adjacent carpet products 1 to be positioned within the aircraft adjoin the aisles (such is in the footwells between seats) may each comprise edge strip 4 forming an edge of the carpet product 1 as described herein. In such embodiments, the adjacent carpet products 1 may be secured to the floor of the aircraft via one or more fasteners, such as double-sided tape. Moreover, in various embodiments, the adjacent carpet products 1 may be secured relative to one another via single- or double-sided tape secured to the edge strip 4 positioned along the backside of the respective carpet products 1. As yet another embodiment, carpet products 1 may be formed to be fit around various components of an aircraft interior, such as seat securing points, and may comprise edges along the portion of the carpet products 1 adjacent the various components of the aircraft interior.
[0043] Moreover, various embodiments are directed to an aircraft carpet kit comprising a plurality of carpet products 1 having an edge formed by an edge strip 4 as described herein. The aircraft carpet kit may comprise a plurality of carpet components 1 configured to fit between various components of the interior of the aircraft to substantially cover at least a portion of the floor of the aircraft. In various embodiments, the aircraft manufacturer, owner, and/or operator may provide specifications regarding the size, shape, quantity, and/or the like of each carpet component 1 to be included in the carpet kit. Various carpet components 1 may be manufactured in accordance with the provided specifications, for example, by cutting (e.g., via a blade, a laser, a water jet, and/or the like) each carpet component 1 from a broadloom carpet product. The edges of each carpet component 1 may be provided with an edge strip 4 in accordance with the process described herein.
[0044]
[0045] Moreover, as shown in
[0046] Accordingly, for elongated carpet products 1 utilized to carpet at least a portion of the interior of the aircraft (e.g., an elongated carpet product 1 configured to carpet an aisle of a commercial passenger aircraft), edge strip material may be applied to the elongated edges of the carpet component 1 via one or more methods as described herein. For example, the edge strip 4 may be secured along the edge of the elongated carpet component in a single iteration (e.g., utilizing an edge forming die 12 at least as wide as the length of the elongated carpet product 1) and/or in a plurality of iterations (e.g., forming an edge along a first portion of the elongated carpet component 1, then forming an edge along a second portion of the elongated carpet component). In embodiments in which the edge is formed in a single iteration, the edging apparatus 10 may comprise a plurality of dispensers in order to apply edge strip 4 onto the edge forming die 12 such that the edge strip material does not cure before the edge forming die 12 is moved to the application configuration. As yet another example, a single dispenser 14 may be provided that is configured to move laterally across the width of the edge forming die 12 sufficiently quickly to complete the extrusion process before the edge strip material cures. As yet another example, the edge forming die 12 may be heated to slow the curing time for the edge strip material such that the dispenser 14 may complete applying the edge strip material onto the edge forming die 12 before a portion of the edge strip material cures.
[0047] In various embodiments, the carpet products 1 of the aircraft carpet kit may comprise a backing 3 and tufts 2 complying with applicable regulations regarding carpet materials that may be utilized in aircraft. For example, the carpet products 1 may be configured to resist burning at high temperatures (e.g., at or above 1500 degrees Fahrenheit). In various embodiments, the backing 3 and/or the tufts 2 may comprise a nylon material and/or a wool material.

[0049] For example, in various embodiments, an edge strip 4 may comprise a pre-formed, solid edge strip 4 that may be secured relative to a carpet component 1. For example, a pre-formed, solid edge strip 4 may be placed adjacent an edge of a carpet component 1 and heated until at least partially liquefied, such that the material of the edge strip 4 may be secured relative to the carpet component. As just one example embodiment, the pre-formed solid edge strip 4 may be placed onto an edge forming die 12 and heated in place. The edge forming die 12 may then be directed against an edge of a carpet component 1, as discussed in detail herein to form an edge strip 4 secured with the carpet component 1.
[0050] As yet another embodiment, the edge strip 4 may comprise a pre-formed, solid edge strip 4 that may be secured relative to a carpet component 1 via one or more fasteners (e.g., double-sided tape, glue, and/or the like).
