Abstract
A sealing shoe assembly for providing superposed sheets with a sealing seam formed by a criss-cross pattern of straight lines by pressing together areas of the superposed sheets comprises a first pair of cooperating sealing shoes each having a plurality of parallel-extending stamping edges oriented in a first direction and a second pair of cooperating sealing shoes each having a plurality of parallel-extending stamping edges oriented in a second direction. The stamping edges of the cooperating sealing shoes are arranged to periodically assume a meshing relationship for pressing together predetermined areas of the superposed sheets passing between the cooperating shoes. The first and second pairs of sealing shoes are arranged for stamping the predetermined areas in sequence for providing the criss-cross pattern.
