Abstract

Abstract 994,978. Packaging. S. OMORI. Sept. 14, 1961 [Nov. 30, 1960], No. 32999/61. Heading B8C. A packaging machine comprises a horizontal filling nozzle around which a film is folded and heat sealed to form a tube, which is filled with material fed from the nozzle by a piston, two pairs of film holding elements positioned at the end of the injection cylinder which clear the contents from a portion of the tube, two sets of dies which operate to seal the tube at ends of the cleared portion, e.g. by applying a clip round the tube, and a cutter intermediate the two dies for cutting the film. The material contained in a hopper 1 is fed to the nozzle 2 by a piston 40. From the position shown in Fig. 14 the piston is rotated through 180 degrees to align an arcuate groove 41 in the piston with an outlet passage 56 to the filling nozzle. The piston is forwarded to eject the material contained in the cylinder out through the nozzle 2. The piston is then rotated through a further 180 degrees to connect the groove to the inlet passage 54 connected to the hopper 1, and withdrawn to the position shown to refill the cylinder with material from the hopper 1. A web 3 of thermoplastics material is fed from a roll 4 and formed into a tube, the longitudinal seam being sealed by an electric heater B having a reciprocating foot 6. The nozzle 2 has a portion of square cross-section where the foot acts. The foot is pressed against one of the flat faces so that a broad seam may be formed. The filled tube is divided into package lengths as follows:-Pairs of plates 8, 81 and 9, 9<SP>1</SP> are positioned just beyond the end of the nozzle. The plates 9, 9<SP>1</SP> are mounted on racks 11, 11<SP>1</SP> keyed to rotatable shaft 10, rotation causing the plates 9, 9<SP>1</SP> to move together or apart. The plates 8, 8<SP>1</SP> are mounted on a similar assembly not shown. From the position shown in Fig. 5 the pairs of plates are moved together by rotation of the shaft 10 to flatten a portion of tube. The pair 9, 9<SP>1</SP> is then moved away from the pair 8, 8<SP>1</SP> as indicated in Fig. 5 to clear the contents from the portion of the tube now between them and a pair of guides (not shown) move in to bunch the flattened portion. Two pairs of dies 27, 28 then operate to apply two metal clips around the flattened and bunched portion of tube between the plates, and a cutter, Fig. 9 (not shown), cuts through the tube between the applied clips.
