Abstract
A form-fill-seal machine in which the cross sealing jaws move in the direction of the moving film during the sealing operation with the continuously moving tube. The drive for the cross sealing jaws include a pair of gear cases on opposite of the sealing jaws, each having two sets of spaced drive shafts. The drive shafts include cranks that impart rotary motion to a pair of link bases for the front and rear sealing jaw. Pairs of parallel links are pivotally connected at one end to the link bases and at the other end to the sealing jaws. The pivot connections of the parallel links include pressure or torsion members which bias the sealing jaws toward engagement.
