ABSTRACT:
A machine for producing helically wound tubular bodies from patterned strip material where the strip material is wound on a mandrel to form an axially movable tube having recurring indicia thereon marking points where the tube is to be cut into discrete lengths at the recurring indicia includes a carriage having a knife array movable into position to cut the tube into the discrete bodies, the carriage being movable axially with respect to the axially movable tube and into synchronization therewith, the carriage supporting structure for sensing one of the recurring indicia and controlling the speed of winding of the tube so that the knife array cuts the tube into discrete bodies at the recurring indicia.
The machine is further characterized by a pair of such carriages which move axially to and fro, the two carriages being locked together and released from locking for traverse of the carriages between advanced and retracted positions.
