摘要:
A method of forming a headliner including a fluted paper central substrate includes forming a fluted paper substrate in a first forming tool (40). The formed substrate (44) is then moved to a second bonding tool (46). A cover layer (22) and an adhesive layer (24) are actuated in the bonding tool to secure the cover layer to the substrate. The bonding tool preferably consists of a heated upper portion (48) adjacent the cover layer and the adhesive, and a cooled lower portion (52) which receives the base material. The use of the cooled bottom portion maintains the dimensional accuracy of the base layer during the bonding process. The heated upper layer ensures efficient and quick actuation of the adhesive to bond the cover layer to the substrate.

摘要:
A method of manufacturing a padded part (l) is proved. The padded part (1) is primarily for use in an item of wear that, in particular but not exclusively, may be a load-bearing harness or belt. The method comprises the steps of providing a first sheet of a flexible material (3) on one side of which is located at least one fastener (10, 11, 12). A second sheet of flexible material (4) is provided and a layered assembly is created comprising, in order, the first sheet of material (4) such that said one side of the first sheet (3) is outermost, a piece of mouldable padding (5), and the second sheet of flexible material (4). Hot melt adhesive layers (7) are provided between the padding (5) and the first and second sheets of flexible material (34). The layered assembly is moulded in a press after or during heating of the layered assembly thereby simultaneously bonding the layers of the assembly together and moulding the layered assembly into a predetermined shape. Preferably, at least one fastener (10, 11) is either secured to said one side of the first sheet (3) prior to creation of the layered assembly and/or another fastener (12) is secured to the first sheet of material (3) when the layered assembly is moulded in the press. The layered assembly is preferably created in a mould tool (17) that is provided with at least one cavity (30) in which the fastener or fasteners (10, 12) located on said one side of the first sheet (3) are inserted whereby the fastener or fasteners (10, 12) are unaffected by the pressure exerted by the press. Preferably also, the fastener or fasteners (10, 11) are attached to the first sheet of material using a jig that facilitates their alignment relative to the first sheet of material.
摘要:
A rigid, contoured insulating sheet is formed from a flexible, substantially uniform thickness mat (43) of loose fibers or open-cell foam, impregnated with an uncured, heat-activable adhesive, e.g., a phenol-formaldehyde resin, by: a) compressing the mat between a pair of complementary, contoured, preheated e.g., 375 DEG F.) dies (19 and 22) that have perforations (4, 18 and 33) across substantially their entire contact surfaces (30 and 50); b) simultaneously ejecting superheated vapor, preferably steam (lines 9, 14 and 40), through the perforations in both dies, the vapor being at a pressure and temperature e.g., 80 psig and 600 DEG F.) sufficient to heat the adhesive in the mat to its activation temperature e.g., 230-350 DEG F.); and c) applying vacuum (line 10) to the mat, so as to pull ambient air therethrough, until the adhesive is substantially set. The process is especially useful for forming contoured, fiberglass, insulation panels for automobiles, e.g., headliner shells.
摘要:
There is disclosed a process (10) for applying a material (12) to a member (14) having an adhesion surface (22). Typically, the process (10) includes applying the material (12) to a mold (26), the member (14) or both. Thereafter, the material (12) is at least partially conformed to the shape of the mold (26).

The invention relates to an interior covering element for a vehicle and to a method for producing the same. According to the invention, said interior covering element (1) for a vehicle comprises the following: a rigid insert (3), which gives the element its shape; a lining sheet (11) consisting of a textile material or similar and covering the rigid insert; a foam layer (13, 14) which is arranged between the rigid insert and the lining sheet and which is subdivided into a first sub-layer and a second sub-layer, such as a first sub-layer (13) which mainly has open cells and is arranged between the lining sheet and the second sub-layer and a second sub-layer (14) consisting of a polyolefinic thermoplastic material(s), which mainly has closed cells and is arranged between the insert and the first sub-layer. The appearance, texture and sound of the element are improved as a result.
摘要:
An insulating laminate (120), which is particularly suitable for a sound attenuating barrier, such as a contoured vehicle headliner. The disclosed embodiment includes a finish lamina (28), which may be preferably cloth-like, and a substrate which is preferably structurally stable and self-supporting and which may be adapted to absorb sound primarily at predetermined higher frequencies. In one preferred embodiment, a thin flexible film (50) is located between the finish lamina and the substrate which is adapted to absorb sound primarily at relative lower predetermined frequencies. The film may include a pattern of openings or holes (52) designed to absorb sound primarily at predetermined lower frequencies. In the disclosed embodiment, the substrate includes a porous fiber mat (34), preferably including fibers having a range of thicknesses to improve sound attenuation at higher frequencies, a structural foam lamina (36a) and a reinforcing scrim (38), preferably comprising spunbonded polyester filaments.
摘要:
A process for forming a multilayer composite insulator (10) includes the steps of forming an insulator precursor (24) by orienting an insulation insert (16) in a desired location between a first facing layer (12) and a polymer based blanket layer (14), applying differential heat to two opposing sides of the insulator precursor and applying pressure to the insulator precursor (28, 30). Together, the applied differential heat and applied pressure mold the insulator precursor to a desired shape while also providing the polymer based blanket material with a first relatively high density (32) adjacent a warmer of the two opposing sides and a zone of relatively low density (34) adjacent the cooler of the two opposing sides. The process also includes the cooling of a molded precursor to set the insulator in the desired shape.
