An accompanying squeezing unit in a machine for winding plastic film onto bobbins, in which at least two spindles are positioned on a rotating plate around a central shaft constrained to an upright of the machine, the group including an accompanying squeezing roll situated on a lever mechanism which is selectively actuated to rotate-oscillate by actuators in order to maintain the squeezing roll positioned on a film in the final winding onto a bobbin positioned on one of the spindles, the lever mechanism being activated when the plate carrying the spindles is rotated to discharge a finished bobbin. The lever mechanism in the group includes two first levers and two second levers articulated relative to each other. |
