摘要

A crosswise heat sealing mechanism in a bag making-wrapping machine is constructed such that: a pair of crosswise heat sealing means (20) provided on the downstream of a former (2) for forming a wrapper (S) into a predetermined shape so as to be opposed to each other across a conveying path of a wrapper (S) and for the purpose of applying to the wrapper (S) to be filled up with a filler material a suitable crosswise heat sealing treatment in accordance with a film thickness and a material quality thereof; a pair of swingable arms (11) for swinging the crosswise heat sealing mechanism; and a path-contact pressure adjusting means (H) for moving the pair of swingable arms (11) toward or away from each other to cause the pair of crosswise heat sealing means (20) to draw a rectilinear path along the moving path of the wrapper (S) and holding the contact pressure between the pair of crosswise heat sealing means (20) at a predetermined one. With this arrangement, the above-described contact pressure is held at a predetermined constant value, so that the wrapper (S) can be prevented from receiving an excessive pressure.
