IPC: B65B31/02
Filed: 2001-09-03
Abstract: PROBLEM TO BE SOLVED: To eliminate many seal tables on a belt conveyer and the cumulative heat on the tables. SOLUTION: A belt 47 is formed with many long and narrow holes 58 at even intervals and moves intermittently a distance equal to that of the intervals of the holes 58. When the opening edge of a plurality of packaged bags 60 filled with items to be packaged are lined up at each hole 58, by the intermittent move of the belt 47, the bags 60 are transported to the lower area of a pressure resistant chamber 44. By the following rotation of a pinion 65, while a machine platen 62 is raised and a seal table 63 protrudes from the hole of the belt 47 as an imaginary line 63a, the chamber 44 is lowered encircling the periphery of the bag 60.
