<P>PROBLEM TO BE SOLVED: To provide a more definite sealing device for an automatic packing machine by adopting a crimp roller section for a pressing section. <P>SOLUTION: A vertical heat sealer (vertical thermally insulated member) comprises a heating block 25 and a pair of crimp roller sections 26 which are energized in opposite directions. The more definite vertical seal can be secured by thus separately adopting the block 25 which heats a structure of the vertical heat sealer (vertical thermally insulated member) and the sections 26 as the pressing sections. <P>COPYRIGHT: (C)2004,JPO |
