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