Abstract:
A method for forming a container, comprising the steps of:starting from a flexible web of heat-bondable material wound on a reel; forming a tubular element of predetermined diameter and height by bending the flexible web of heat-bondable material and bonding together opposite sides thereof at a first station; thereafter, mounting the tubular element over a support for the tubular element fixed to a rotatable endless conveyor at the first station; thereafter, closing a first end of the tubular element to form an open container at a second station and a third station downstream from the first station; inserting the container into a mould, heating the container, forcing walls of the container against inner walls of the mould, opening the mold and withdrawing the support and the container from the mould at a fourth station downstream from the third station and thereafter, withdrawing the container from the support.
