Abstract
In a process for connecting material segments made of an elastomere or of a thermoplastic material the sections to be joined (3,4) are placed between two pressure beams (1,2) in the area of the seam (5) to be created. The pressure beams are not mechanically connected to one another. The forces necessary to hold and to attach the material segments (3,4) are generated by the evacuation of suction chambers formed between the cavities (9) in the contact surfaces (6a,6b) of the pressure beams (1,2) and the segments to be joined (3,4).
