BRIEF DESCRIPTION
(18) Therefore, it is the objective of some embodiments to provide a method for the manufacture of sports articles that allows for substantially automating the manufacturing process while avoiding—or at least reducing—loss of quality.
(19) This objective is met by a method for the manufacture of a sports article, in particular a sport shoe, comprising the operations of (a.) providing at least one laminar component; (b.) providing at least one three-dimensional object; and (c.) placing the component onto the object via a first roll while simultaneously moving the object relative to the roll.
(20) The laminar component may, for example, be a patch to be placed on a three-dimensional shoe upper, for example, on a lasted shoe upper. The roll helps to press the laminar component against the three-dimensional object. To assert this pressure over the entire length of the laminar component, the object may be moved relative to the roll so that the roll rotates. In this way, the laminar component may be firmly placed onto the three-dimensional object. The roll may closely follow the contour of the surface of the three-dimensional component so that the contact pressure is substantially the same along the entire length of the laminar component. In this way, the component may be placed both on convex and concave portions of the three-dimensional surface.
(21) It should be noted that some embodiments may be applied to manufacturing any kind of sports articles including footwear, apparel, accessories, balls, etc. For example, some embodiments may be used to attach reinforcing patches to garments, such as sports bras.
(22) The method may further comprise the operation of placing the component on a conveyor belt. This allows for the processing of a number of components so as to either place multiple components onto the object and/or to apply components to multiple objects.
(23) The first roll, also known as a contact roll, may be a pulley of the conveyor belt. Thus, the first roll may simultaneously support transporting the component and placing the component onto the object. As the component is directly supplied from the conveyor belt to the object, the risk of the component getting stuck may be minimized.
(24) The conveyor belt may convey the component to the first roll. In this way, multiple components may be fed to the roll and placed onto the object and/or at least one component may be placed onto multiple objects.
(25) The conveyor belt may be compliant. A compliant conveyor belt may yield so as to adapt to the surface contours of the object onto which the component is to be placed. As such, the compliant conveyor belt may comprise a comparable soft surface.
(26) The method may further comprise the operation of pressing the component in the direction of the first roll. This may include using a clamping roll and/or an airflow. This may avoid the potential that the laminar component is unintentionally lifted off the first roll or the conveyor belt when it is pressed against the object. Thus, this measure is especially useful for long and/or stiff laminar components, and/or three-dimensional objects with high curvature. Additionally, a clamping roll and/or an air-flow may allow exertion of tangential tension to the component during application.
(27) The operation of providing the component may comprise providing the component on a liner. The component may adhere to the liner, thus forming an adhesive tape. Using a liner simplifies handling of the component, or components, as these may be cut from an endless roll of adhesive tape. Additionally, a liner increases the placement accuracy since components are generally transported in a defined manner. Generally, the adhesive force between the component and the liner may be substantially lower than the adhesive force between the component and the object. In this way, the component may easily be separated from the liner before it is placed onto the object, yet the bond between the component and the object may be sufficiently large.
(28) The method may further comprise the operation of guiding the liner over the first roll, such that the component separates from the liner. In this way, the liner may protect the adhesive side of the component until immediately before the component is placed onto the object. This avoids, for example, dust from adhering to the adhesive side of the component which could undesirably reduce its adhesive force. In addition, the movement of the component caused by the first roll may be used to separate the liner and the component, for example, by a blade and/or by winding up the liner on a roll. In this way, an additional mechanism for separating the component and the liner may be dispensed with.
(29) The method may further comprise the operation of guiding the liner over a second roll, such that the component separates from the liner and is transferred to the first roll. This mechanism allows for separation of the liner and the component while the component is fed to the first roll. The adhesive side of the component may be protected as long as possible.
(30) The first roll may be compliant. A compliant roll may yield so as to adapt to the surface contours of the object onto which the component is to be placed. As such, the compliant roll may comprise a comparable soft surface.
(31) The objective underlying some embodiments is also met by a method for the manufacture of a sports article, in particular a sport shoe, comprising the operations of (a.) providing at least one laminar component on a liner; (b.) providing at least one three-dimensional object; and (c.) placing the component onto the object by transferring the component from the liner onto the object.
(32) In some embodiments, the component may be accurately positioned over the surface of the three-dimensional object while still being held by the liner. In particular, the component may be positioned substantially parallel to the surface of the three-dimensional object, even in convex or concave regions, and then the component may be placed onto the object. In addition, using a liner simplifies handling of the component or components as these may be cut from an endless roll of adhesive tape. Generally, the adhesive force between the component and the liner may be substantially lower than the adhesive force between the component and the object. In this way, the component may easily be separated from the liner before it is placed onto the object, yet the bond between the component and the object may be sufficiently large.
(33) The operation of placing the component may comprise pushing the component into the direction of the object. In this way, the component may be separated from the liner and placed onto the object.
(34) The method may further comprise the operation of pushing the component into the direction of the object via an air blast, such that the component is placed onto the object. Using an air blast is beneficial as it allows for quick acceleration of the component towards the object, such that a plurality of components may be placed at high frequency, thus decreasing the production time. Furthermore, the air blast may apply pressure to the component, once the component has been placed onto the object. In this way, the adhesive bond between the component and the object may be improved. In addition, the pressure exerted by the air blast may help to conform the component to the surface of the object, for example, in convex or concave regions.
(35) The method may further comprise the operation of holding the component by low pressure before it is placed onto the object. Thus, the component may be handled and correctly positioned over the surface of the object before it is applied thereto.
(36) The method may further comprise the operation of peeling off the component from the liner before pushing the component. In this way, the air blast may not need to generate the force required to separate the component from the liner. Instead, the entire energy of the air blast may be used to accelerate the component into the direction of the object and to exert pressure on the component.
(37) The method may further comprise the operation of pushing the liner in the direction of the object, such that the component is transferred from the liner onto the object. In this embodiment, a separate operation of separating the component from the liner, e.g. by peeling off, may be omitted. In this way, the method may be simplified and the frequency of placing components may be increased.
(38) The liner may be air permeable and the method may further comprise pushing the component into the direction of the object via an air blast, such that the component separates from the liner and is placed onto the object. In some embodiments, a separate operation of separating the component from the liner is dispensed with.
(39) Generally, the methods of some embodiments may further comprise the operation of placing the component on a robot arm. The robot arm allows movement of the component in the correct position and orientation before the component is placed onto the object. In some embodiments, the object may rest while the component is placed thereon. For example, a plurality of objects may be transported on a conveyor belt. Each object may be transported to the robot arm, where at least one component is placed thereon.
(40) Generally, according to some embodiments, the first roll may be mounted on a robot arm. As described above, this arrangement allows for a correct positioning and orienting of the component while the three-dimensional object may generally rest.
(41) Generally, according to some embodiments, the component may comprise an adhesive. This allows the component to be placed without additional adhesives to be applied, thus simplifying the method and avoiding additional operations.
(42) Generally, according to some embodiments, the object may be a shoe last. In this way, an upper can be manufactured by placing at least one component onto the shoe last as described herein. It is possible to completely form the three-dimensional upper by placing patches and/or components onto the last avoiding the need for a base material. Alternatively, the upper may be formed via patches placed on a base material while the same is lasted. In any case, as the upper is substantially formed in its final three-dimensional shape, wrinkles, which may appear in prior art methods as described above, may be avoided or at least substantially reduced. In addition, the number of process operations (e.g. forming a three-dimensional upper from a two-dimensional upper) may be reduced and seams can be avoided. Product modifications may be made very late in the process.
(43) Generally, according to the method of some embodiments, the object may be a preformed component of the sports article. For example, the object may be a preformed shoe upper onto which additional reinforcements and logos are placed. As the object already has its final three-dimensional shape, wrinkles may be avoided as described herein.
(44) Some embodiments also relate to a sports article which has been manufactured by use of a method according to some embodiments. Thus, the sports article may generally be manufactured by building up a number of small components (e.g. patches). Alternatively, the sports article may be built up by extruding streams of material.
