ABSTRACT:
A vessel manufacturing system is disclosed which manufactures vessels having a rectangular configuration from a tubular body which is filled with a content. The system includes a transverse sealing unit which applies transverse seals to the tubular body at a given spacing, a cutter for cutting through the transverse seals in the succession of vessels which are formed by the transverse sealing unit, a diversion unit for handing the vessels separated by the cutter by changing the orientation of the vessel from one in which the pair of transverse seals are spaced apart in the circumferential direction of a rotatable member to another in which the pair of transverse seals are spaced apart in the radial direction thereof, and a vessel shaper receiving vessels from the diversion unit to shape them into a rectangular configuration and adhesively connecting the flaps to the body. With the vessel shaper of the invention, the vessels can be manufactured continuously and at a high rate, using an overall arrangement which is compact as compared with the prior art.
