CPC B21C 37/124 (2013.01) | 15 Claims |
1. A pipe tubular reinforcement forming machine, comprising:
a first feeder, configured to unwind a first tape;
a profiler comprising at least one upstream profiling stage configured to receive the first tape from the first feeder and configured to profile the first tape to form a pre-profiled first tape;
a second feeder, configured to unwind a second tape, the second tape being a flat tape;
an intermediate joining stage configured to receive the second tape as a flat tape from the second feeder and configured to join the pre-profiled first tape and the flat second tape; and
at least one downstream profiling stage configured to jointly profile the first tape and the second tape received from the intermediate joining stage and to form a combined profiled strip,
wherein the machine is without a profiler within the second feeder or between the second feeder and the intermediate joining stage such that the transverse section of the second tape remains constant in the second feeder, up to the intermediate joining stage,
the at least one upstream profiling stage and the at least one downstream profiling stage each have at least two opposite rollers defining between them a profiling interspace, and
the at least one downstream profiling stage has a profiling interspace that comprises,
at least a first region configured to jointly deform the first tape and the second tape, and
at least a second region configured to deform only the first tape, without deforming the second tape.
