ABSTRACT:
A machine for transporting a web particularly a web of flexible material of indefinite length. The device comprises a pair of rotary clamping groups, each clamping group having the form of an endless carrier of clamps. Each rotary clamping group is pivotally adjustably attached to a frame support structure at its lower portion, to thereby admit of rotary adjustment about its lower axis of return. Further, the two clamping groups are horizontally and vertically adjustable. The clamps of each clamping group are cam operated so that clamping takes place over a portion of the run of each, the clamps being carried by and pivotally attached to endless chains, there being two endless chains for each rotary clamping group.
