ABSTRACT:
Apparatus for forming a chain of interconnected containers from a continuous web of flexible material such as plastic. The apparatus includes upper and lower assembly portions 10a, 10b, the upper portion reciprocally mounting a heat sealing head 12 having a pair of depending jaws 44 that define heat sealing edges 50. The head is driven downwardly until the edges 50 contact associated contact bars 90, 92, clamping the web material therebetween and forming a pair of spaced, parallel transverse heat seals 98, defining leading and trailing edges of adjacent containers 99a, 99b. A perforating device 100 reciprocally mounted in the assembly portion 10b includes a perforating wheel 102 reciprocally movable between the contact bars 90, 92 is cycled to cut a transverse perforation in the web material between the adjacent heat seals 98. The web remains stationary during both the heat sealing and perforating cycle so that the heat seals and perforation are precisely registered. The upper portion 10a of the assembly is pivotally attached to the lower portion 10b which is stationary, to facilitate access to the web feed path.
