Abstract
A machine that includes a first feeder, able to unwind a first tape; a profiler comprising an upstream profiling stage able to profile the first tape to form a pre-profiled first tape; a second feeder, able to unwind a second tape, the second tape being a flat tape. A profiler that includes an intermediate joining stage able to receive the second tape as a flat tape from the second feeder and able to join the pre-formed first tape and the flat second tape; and at least a downstream profiling stage configured to jointly profile the first tape and the second tape received from the intermediate joining stage and form a combined profiled strip.
Claims15
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.
A pipe tubular reinforcement forming method comprising:
- unwinding a first tape from a first feeder;
- feeding the first tape from the first feeder to at least one upstream profiling stage of a profiler to form a pre-profiled first tape;
- unwinding a second tape from a second feeder, the second tape being a flat tape;
- feeding the second tape as a flat tape from the second feeder, without profiling, to an intermediate joining stage of the profiler and joining the pre-profiled first tape and the flat second tape in the intermediate joining stage;
- jointly profiling the first tape and the second tape received from the intermediate joining stage in at least one downstream profiling stage to form a combined profiled strip,
- 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.
A pipe tubular reinforcement forming machine, comprising:
- a first feeder, configured to unwind a first tape;
- a profiler comprising at least an 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 a 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 second feeder comprises a second unwinder and a second guide roller to feed the second tape in the intermediate joining stage as a flat tape, the second guide roller being configured to change direction of the second tape's local longitudinal axis, without modifying its cross section.
