摘要:
A system and method for producing window components using polymer based, metallurgy based, extruded, injection molded, or wooden lineal material. The lineal material is notched at intervals calculated to include a stretch treatment and folded to form window components such as window sashes, frames, and the like. Internal reinforcing members may be welded within the joints formed by folding at the notches. The notching system and method provide low cost, highly reliable, low defect production of multi-sided window components from a continuous piece of lineal material.

Vibration welded joint structures, methods, and apparatus for thermoplastic members are disclosed. A welded joint structure includes first and second thermoplastic members and an interposed junction piece vibratory welded to the first and second members at respective welding surfaces. At least one of the welding surfaces partially defines an angle, in a plane normal to the interposed junction piece, between an unwelded portion of the first member and an unwelded portion of the second member. The junction piece may include surfaces for forming vibratory welded bonds with the first and second thermoplastic members and a component holder, physically coupled to those surfaces, for enabling the junction piece to hold a further component.

A frame (20) for supporting an article includes a first frame section (36) and a first flange (62) extending to a first end (56). The frame (20) also includes a second frame section (38) and a second flange (64) extending to a second end (60). A notch (68) is formed in the first flange (62) and defines a flange finger (70) between the notch (68) and the first end (56). A retention opening (32) is formed in the second end (60) of the second frame section (38). A retention corner (94) for the frame (20) is formed between the first frame section (36) and the second frame section (38) by inserting the flange finger (70) of the first frame section (36) into the retention opening (32) of the second frame section (38).

A framed panel and related method of manufacture are disclosed. A framed panel unit includes a panel along the edge of which thermoplastic frame members are disposed. The frame members have first and second opposed side walls which define a channel for receiving the edge of the panel. The channel of each frame member has spacers between the panel and each side wall for spacing the panel from the side walls. Prior to welding together the ends of the frame members, the spacers retain the frame members on the panel. The panel may include multiple opposed sheet members with a spacer between the sheet members spacing them apart, and a reactive thermoplastic sealant material bonding the sheets to the frame members. An associated method of forming a named panel, frame members for a panel, and a spacer component for use in mounting a panel within a channel of a frame member are also disclosed.

A tubular assembly that includes a plug (45) residing within at least a portion of each of a first tube (12) and a second tube (30), is described. Each of the first and second tubes have perforations (21 and 39) that are separately aligned with cavities (51) in the exterior surface (48) of the plug (45). Plastic material (54) is molded separately through the perforations (21 and 39) of the first and second tubes (12 and 30) and at least partially fills the cavities (51) of the plug (45). The edges (24) of the perforations (21) of the first tube (12), and the edges (42) of the perforations (39) of the second tube (30) are embedded in the plastic material (54) extending therethrough, thereby fixedly attaching the first and second tubes to the plug therein.

A method is provided for manufacturing a support frame of a rectangular display panel within a short working time. The method includes a process of taking out L-shaped component members each having convex portions and concave portions arranged alternately at an end portion in a manner that each of the convex portions and concave portions is bilaterally symmetrical, while a shear droop and a burr are formed on an end portion and process of fitting and coupling end portions of L-shaped component members by placing the convex portions and the concave portions in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that that the convex portions and the concave portions are pushed towards each other and by pressing the convex portions and the concave portions using a pair of metal molds.

According to the invention, the section (2) comprises a double-sided adhesive strip (8) which is covered with a protective film (11). The aforementioned protective film (11) is removed by way of a pull tab (12) before gluing, the tab consisting of two tab parts (15) which are positioned on either side of a slit (16) in the film. The automated method comprises, in the extrusion line, a step whereby the pull tab (12) is joined to the adhesive-covering protective film in the middle of the adhesive area transversely to the section. The tab and the protective film are subsequently cut in order to produce two tab parts which are each connected to the end of one length of protective film (18) which is intended to be torn off. The invention is particularly suitable for use in the car industry and in building and for producers and users of extruded sections which are glued using double-sided adhesive.
摘要:
A material application system for applying a panel of material to a framework with a shoe for retaining the framework, a nest, opposed mechanisms for retaining opposite portions of the panel of material traversing between the shoe and the nest, an arrangement for selectively moving the shoe and the nest into and out of an engaged position wherein the panel of material is sandwiched between the shoe and the nest and a disengaged position, and an arrangement for inducing an attachment of the panel of material to the framework. The opposed mechanisms can be clamping mechanisms, which can be segmented and individually moveable to enable variable pretensioning. A contoured deflection control member can alternatively produce variable pretensioning. A pressing arrangement with a tooth member can press a locking spline into a groove in the framework to secure the material.

A tubular assembly that includes a plug (45) residing within at least a portion of each of a first tube (12) and a second tube (30), is described. Each of the first and second tubes have perforations (21 and 39) that are separately aligned with cavities (51) in the exterior surface (48) of the plug (45). Plastic material (54) is molded separately through the perforations (21 and 39) of the first and second tubes (12 and 30) and at least partially fills the cavities (51) of the plug (45). The edges (24) of the perforations (21) of the first tube (12), and the edges (42) of the perforations (39) of the second tube (30) are embedded in the plastic material (54) extending therethrough, thereby fixedly attaching the first and second tubes to the plug therein.
