ABSTRACT:
Continuous superimposed webs are interlocked together along opposite marginal edges by sets of superimposed tongues provided in the webs which interengage to effect an interlock. Each set includes at least a pair of superimposed tongues disposed along a line forming an angle with an adjacent marginal edge so that one of the tongues is staggered relative to the other in the direction of feed of the webs through a web processing machine. Thus, during separation of the plies in the direction of feed the forwardmost superimposed tongues are separated before the rearwardmost tongues thereby avoiding simultaneous separation of the tongues and decreasing the resistance offered by the tongues upon ply separation.
