Abstract
Coiler for winding a strip product, comprising a supporting frame (1) supported, on at least one side, by a hollow tubular shaft (2) rotating in at least one fixed bearing (21) centered about an axis (x'x) of rotation of the frame, at least two winding mandrels (3a, 3b) each mounted on an off-centered shaft of rotation (31), each mandrel shaft (31) being fitted into and locked in rotation with a tubular sleeve (5) supported by two spaced bearings (51) each mounted in a crown (52) fixed onto said rotating frame (1). At least two autonomous motors (6) provide rotational drive, respectively, for the two mandrels (3a, 3b), and each comprises a rotor (62) fitted over and locked in rotation with the tubular sleeve (5) and a stator (61) mounted on a side wall (53) extending between and attached to the crowns (52). The autonomous motors (6) are associated with power supply circuits passing through the inside of the tubular shaft (2) of the rotating frame (1) and linked to a power source via a rotating connecting device (64).
