Apparat zum Formen von Behältern.

摘要

The invention relates to an apparatus for forming tubular containers having a square to rectangular cross section and a bottom from planar heat-sealable blanks (B1). The apparatus comprises an apparatus frame having a plurality of treating stations (S1...S8) including a blank feed station (34) and a rotary body (31) having radial mandrels (32) and intermittently drivingly rotatable so as to stop each of the mandrels at the plurality of treating stations successively. On each of the mandrels there are means for holding the planar blank to the mandrel fittably therearound and feeded to the holding means at the blank feed station. A series of devices has been arranged one after another along the path of movement of the mandrels extending from the blank feed station for forming the blank held by the holding means into a tube as fitted around the mandrel and closing one end of the tubular blank to provide the bottom and form the container.
