摘要

The unwinder (1) has a base plate (2) directly connected to a telescopic handle (3b), where an upper assembly (4) is slid on the telescopic handle and provided with a butterfly screw (22) that blocks on the handle. The upper assembly comprises a ball bearing allowing a conical low part (7) to turn freely with a stretchable film roller (23), where the film roller rests on the base plate that is made of a material with low friction coefficient. A brake system is arranged between a pushbutton (5) and an intermediate part (6).
