Abstract
Apparatus for sealing thermoplastic sheet materials or for closing packs, such as bags, made of such sheet materials with the aid of heated sealing jaws ( ) and mating jaws ( ), which accommodate between them the sheet materials and/or folding or closing flaps which are to be connected, the (non-heated) mating jaw ( ) having an elastically deformable abutment surface for the sheet materials which are to be sealed, such that any possible elevations produced by a multi-layered design of the folding or closing flaps are compensated for by the elasticity of the abutment surface of the mating jaw. The sealing jaw ( ) and/or mating jaw ( ) can be moved by a special, oil-free actuating mechanism which, during continuous driving, brings about a standstill phase of the sealing jaw or mating jaw, which can be moved back and forth.
