ACCOMPANYING SQUEEZING UNIT IN A WINDING MACHINE FOR POLYMER FILM Russian patent published in 2018 - IPC B65H19/22 

FIELD: transportation.

SUBSTANCE: invention relates to winding equipment. Accompanying squeezing unit is used in a winding machine for winding polymer film onto bobbins. Winding machine has at least two spindles. Spindles are positioned on a rotating plate. Plate is rotatable about a central shaft. Shaft is constrained to an upright of the machine. Squeezing unit comprises an accompanying squeezing roll. Roll is situated on a lever mechanism. Lever mechanism is selectively actuated to rotate-oscillate by means of respective actuators. Lever mechanism maintains the squeezing roll positioned on a film in the final winding onto a bobbin positioned on one of spindles. Lever mechanism is activated when the plate carrying the spindles is rotated to discharge a finished bobbin. Lever mechanism comprises two first levers and two second levers. Levers are articulated with respect to each other. Avoiding the capturing of air when the spindle rotates.

EFFECT: productivity is increased.
