ABSTRACT:
The invention relates to a process and an arrangement for the three-dimensional forming of a fabric. The process comprises the steps of providing a countermold; preparing a complex sheet by superimposing a sheet of plastics, hot-melt material and a fabric; die-cutting the complex sheet; superimposing the die cut complex sheet over the fabric; attachment of the die cut complex sheet to the fabric by pressing and heating until the fabric is impregnated by melting of the hot-melt material; and application of the ensemble of the complex sheet and fabric to the countermold by blowing pressurized air. The arrangement comprises a frame receiving the fabric to be formed and which is movable through various workstations wherein the process steps take place.
