摘要
Drive mechanism for the welding jaws of a film-welding appts. comprises a double elbow lever system for moving the welding jaws towards and away from each other, which is combined with a connecting shaft put into a reversing rotation by a drive shaft. A lifting mechanism imparts a reciprocating motion to a support carrying the welding jaws. The drive shaft is designed as a universal-joint taking up variations of length occurring during operation, which is connected with a rocking lever system on the drive side and positively connected to the support on the welding-jaw side. Base height of the welding jaws is infinitely variably adjustable together with automatic adjustment of the working stroke of the jaws.
