Manufacturing procedure for textile piece e.g. for motor vehicle seat or trim component includes pre-assembly and thermal adhesion of plastic foam and textile layers

摘要

The procedure for making a textile piece from two components such as a plastic foam base (20) and a textile covering layer (30) consists of a first stage in which the components are pre-assembled face-to-face to form a complex layer (25), and a second stage combining two operations: thermal adhesion of the two layers and cutting out to the required shape to make the piece (35). The procedure for making a textile piece from two components such as a plastic foam base (20) and a textile covering layer (30) consists of a first stage in which the components are pre-assembled face-to-face to form a complex layer (25), and a second stage combining two operations: thermal adhesion of the two layers and cutting out to the required shape to make the piece (35). The pre-assembly stage can include a supplementary stage in which air is evacuated from between the two layers, while the thermal adhesion stage consists of applying a pressure over all or part of the piece by a heat generator (3) that transmits heat at a pre-determined temperature, at least round the edges of the piece before they are cut by a shearing tool (2). The adhesion and cutting operations are carried out on a machine with a table (11) supported by a rigid frame (10), into which the layers of material are fed by a drive (40), with the heat generator and cutter mounted above the table.
