"STRIP GUIDANCE SYSTEM FOR MACHINES THAT FROM PIPES FROM CONTINOUS PROFILED AND SPIRALLED STRIPS" for machines that produce spiraled tubes (1 ) or pipes from continuous strips (2) that are wound on a roll (3), forming first a profile of at least one continuous flat strip (2) of metal or any other type of smooth material, which after the profiling process are spiraled and interlocked to itself to form a continuous segment of spiraled pipe (1 ) or hose and that the strips (2) raw materials are usually provided and stored in the form of pancakes, rolls (3) or coils. The strip is fed from the storage area to the initial profiling stage of the process by means of a feeding mechanism (4) in such manner that at least one strip (2) is unwound by guides (5) and induced in a spiral pathway (6) along the machine axis (7), and that in order to keep the strip (2) on the said spiraled trajectory (6) the system includes secondary guides (10) which together with the primary guides (5) act as to limit the deformation and bending of the strip (2). |
