Description

Technical field

[0001] The present invention relates to a device and a method for thermally bonding a flexible outer cover to a support, and more particularly, for bonding a fabric or leather outer cover to a support composed of a frame and a molded element made of foam Physically, to produce seat trim. Background technique

[0002] Various methods and devices for thermally bonding a flexible outer cover to a support are known. For example, the document GB 2 192 334 describes a method in which a flexible outer cover is coated with a layer of hot melt adhesive and then processed in a heated rigid mold before being formed into a support. Document EP 0 951 985 proposes to cover the support body with an outer cover, and then press the outer cover onto the support body by means of a flexible bag filled with hot fluid. From the document US 5,407,510 there is also known a method of covering the shaped supports with a flexible outer cover and fixing them with a pipe system flowing thro...
