ABSTRACT:
Equipment that lays flat films or tubular films extruded by a blown film extrusion installation has at least one roller, which guides the walls of the film or the tubular film. The lay-flat equipment has at least one device that influences the rotational speed of the roller by providing a torque that can be transferred onto the roller by a transfer device. The transfer device provides for slippage between the roller and the device that provides the torque, thereby ensuring a smooth transfer of torque and preventing damage to the film.
