An Edge-Banding Apparatus and Method
An edge-banding apparatus is provided and configured to apply an edging strip having a heat activated layer to a substrate or work piece. The apparatus uses localised heat generated from a controlled flame from combustible fuel to apply heat to the edging strip to active the heat activated layer.
The apparatus comprises: a. an edging strip feeding device to feed the edging strip along a predetermined path towards the substrate or work piece; b. a source of combustible fuel; c. a fuel delivery device in fluid communication with the source of combustible fuel such that combustible fuel can be delivered to the fuel delivery device; and d. an ignition device configured to ignite the combustible fuel at or near the fuel delivery device such that a controlled flame is generated by the fuel delivery device;
The apparatus further comprises one or more controllers configured to control one or more properties of the controlled flame of combustible fuel such that the heat from the flame activates the heat activated layer of the edging strip such that the edging strip is applied to the substrate or work piece.
A method of applying an edging strip having a heat activated layer to a substrate or work piece is also provided.
Method and device for applying protective sheeting of polymer material to a pipeline
A method of applying protective sheeting of polymer material to a pipeline extending along a longitudinal axis and having a cutback bounded at opposite axial ends by two end portions of respective protective coatings of polymer material, the method including directly heating the free faces of the end portions; extruding and simultaneously winding about the pipeline a protective sheeting wide enough to cover the cutback and the end portions; and compressing the protective sheeting against the pipeline, the end portions included.
METHOD FOR PRODUCING A MULTI-COMPONENT INJECTION-MOLDED PART
A method for manufacturing a multicomponent injection-molded part is provided. A first plastic component is manufactured with the aid of a first injection molding step, and a second plastic component is at least partially injection-molded onto or over the first plastic component with the aid of a second injection molding step, so that a material composite is formed with the two plastic components. At least one part of an edge area along the parting line between the two plastic components is heated by means of a heat source for the purpose of sealing the two plastic components to each other in the edge area.
LAMINATE FOAM AND METHODS OF MAKING LAMINATE FOAM
A laminate foam material and a method of making laminate foam material is provided. The laminate foam material includes a layer of non-foam material sandwiched between two layers of foam material. The non-foam material is bonded to the foam material, such as with a bonding agent and/or by heating respective surfaces of the foam material until the surface softens or melts. When a heating process is utilized, the non-foam material is pressed against the softened or melted foam material. As the foam material begins to cool, the non-foam material becomes bonded to the foam material. The non-foam material is narrower than the foam material and is positioned relative to the foam material such that the edges of the non-foam material are concealed by the foam material. Foam products, such as foam mats, can be formed from the laminate foam material by cutting across the width of the foam material.
Planar structure for joining at least two components
The invention relates to a planar structure for joining, in particular for the material-uniting joining, of at least two components. According to the invention, the planar structure is flexible and formed by at least one reaction strand. The reaction strand comprises a preferably cylindrical core, which is provided, at least in some areas, with a coating, which is constructed with a plurality of coaxially applied layers with a small thickness. To produce the layers, two different materials are used, the layers being constructed alternately with one of the two materials. Because of the high degree of flexibility of the reactive planar structure and its arbitrary area extent, components with a complex geometry in the region of the joint faces as well as large-format components can be joined in a material-uniting manner without problems. The reactive planar structure can be produced here using the methods known from textile engineering with virtually any dimensions and, in addition, by a continuous industrial production process. Moreover, the invention relates to a method for providing a material-uniting connection between two components, in particular by means of the planar structure according to the invention.
