Abstract: An improved form, fill, seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web including means to attach a pair of mated, resealable closure strips to the base web. The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of applying the closure strips, forming, filling, sealing and separating the reclosable containers are performed during periodic stops of the machine. The machine is further characterized by its use of two pairs of web belts to move the web through the machine. A first pair of web belts initially receive the folded web stock and partially form and completely fill the containers. The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts.

Abstract: A form, fill, seal and separate packaging machine wherein receptacle forming, filling and sealing is accomplished by a plurality of stations disposed along the path of travel of a web which continuously moves through the packaging machine. Both the base web material and the lid web material are supplied to the packaging machine from supply rolls of appropriate material. Not only are the work stations of the machine constructed and disposed so that the packaging operation is performed on a continuously moving web, but also both the base and lid web supplies include primary and secondary rolls so that the source of web material may be replenished without interrupting the continuous movement of the web material through the machine. Once the receptacles have been formed, filled and sealed, the packaging machine further includes an intermittent drive station for perforating and cutting the sealed receptacles from the main web body.
