AUTOMATIC BELLING MACHINE AND METHOD FOR BELLING PIPES MADE OF THERMOPLASTIC MATERIAL

摘要

A belling machine (1) for pipes (T) made of thermoplastic material comprising: an infeed zone (Z1) of the pipes (T) and an outfeed zone (Z4) of the pipes, means (21) for organised picking up the pipes at a station (2) for forming groups of pipes, at least one heating station (4), a forming station (5), a station (6) for unloading the pipes (T) configured to release, one at a time, the pipes (T) at least towards the outfeed zone (Z4), a movement device (7) designed to move each group of pipes (T) along a main path (P1) for feeding the pipes (T) and a sorting device (63) configured to direct the pipes (T) from the main path (P1) selectively from the main path (P1) towards at least a first path (64) and a second path (65), located for at least part of its length at a different height from the height of the first path (64).
