ABSTRACT:
A method for unwinding packaging film is provided for a carriage which includes a stand, a supporting shaft for a film reel and a roller device, and the carriage is intended to be incorporated in a packaging machine for wrapping loads. Plastic film is removed from a roll and is longitudinally stretched between two rollers, has its width reduced and longitudinal creases put into it, and is associated with the load to be wrapped. Between the stretching rollers and end film unwinding roller, the film passes through a slit of a creasing member which reduces the width of the film by forming longitudinally extending creases along its width. The overall width reduction of the film is controlled by controlling the longitudinal angle of the slit relative to the axis of the stretch and unwinding rollers.
