Abstract: A packaging line station having a frame, a die assembly, a drive motor, and an anvil roller. The frame has a base with two vertical stanchions extending upwardly from sides thereof and a top cross-member affixed across the stanchions. The die assembly includes a yoke affixed to the cross-member, a die wheel rotatably affixed to side arms of the yoke, a drive shaft affixed to the die wheel and a cutting die affixed to the die wheel. The drive motor is connected to the drive shaft. The drive shaft and the anvil roller extend between the stanchions. The cutting die and the anvil roller and spaced apart by a nip for receiving a traveling web. As the web passes through the nip the web is cut by blades of the rotating die to form a slit. An adhesive resealable tape or label is then applied over the slit.

Abstract: A gearbox has a partly toothed drive gear wheel with a toothed segment and a toothless segment on its circular peripheral surface. A driven gear is completely toothed and meshes with the toothed segment of the drive gear when it is presented to a mesh point between the gears. Pawls on the gear shafts synchronize the initiation of the mesh. The number of teeth on the drive gear is selected so that 360 degrees of rotation of the drive gear results in 360 degrees of rotation of the driven gear. As the drive gear toothless segment just reaches the mesh point, a brake on the driven gear shaft is actuated to accurately stop the motion of the driven gear shaft. The driven gear shaft is thereby halted while the drive gear is free to turn until its teeth once again reach the mesh point.

Abstract: A resealable carton, having a product-containing bag liner, is constructed such that the liner bag is positively held in the folded, sealed condition by the incorporation of a fold support ledge which extends inwardly from an end wall of the carton. The bag is held against the support ledge by one of the closure flaps, which creates a tightly constructed U-shaped fold in which the bag is folded around the end of the closure flap. The liner is secured in that position in part by being captured between the top of the inner closure flap and an outer closure flap along a top run of the fold. A bottom fold is held between the support ledge and the inner closure flap. The support ledge may be formed in various ways including folding the end wall, embossing the end wall or forming the ledge by adding a bead of self-adhesive material to the end wall.
