ABSTRACT:
A continuously travelling web of material is processed at longitudinal intervals between a pair of confronting transverse processing tools. The tools are mounted on carriers guided in pairs on endless chains to follow a path composed of two parallel straight sections joined at the ends by semi-circular sections, the latter being relatively adjustable. The chains are guided on adjustable sprockets so that their runs are parallel and overlap. Confronting extensions of interconnecting hinge pins for the links of the chains are engageable in recesses provided in the tool carriers.
