METHOD AND INSTALLATION FOR THERMOFORMING OF CONTAINERS LIMITING MATERIAL LOSSES

摘要

The invention concerns a method and an installation for forming containers in a thermoplastic material strip (10) moving past step-by-step. The method consists in locally drawing the strip (10) to form at least a thin zone (11) of the strip between thick zones (9), increasing the spacing between said thick zones and thermoforming said containers (20) in said thick zones (9) while the scrap disposal zone is arranged in a thin zone (11)
