Patent ID: 8079205

Claim:
A machine for the winding of tubular products ( 20 ) with tensioned wires ( 8 ) including, at least one disc ( 51 - 52 , 101 - 103 ) assembled to rotate on a base structure ( 2 ), a motor ( 9 ) adapted to drive the rotation of the disc ( 51 - 52 ), a plurality of coils ( 3 ) assembled to rotate on supports ( 4 ) integral with said disc ( 51 - 52 , 101 - 103 ), and tensioning means ( 18 , 30 - 31 , 40 - 42 ) adapted to maintain a constant tension of the wires ( 8 ) during the winding of the tubular product ( 20 ), characterized in that it also includes a plurality of driving motors ( 5 ) mounted on said at least one disc ( 51 , 52 , 101 - 103 ) associated one by one to their respective coils ( 3 ) adapted to feed the wires ( 8 ), and operation means ( 70 ), pneumatic means ( 18 , 50 ) and a plurality of potentiometers ( 19 ) associated one by one to respective coils ( 3 ) adapted to control the unwinding speed of the wires ( 8 ) from the coils ( 3 ), which are driven by the motors ( 5 ).
