Abstract
This device ensures insertion of a film into the entrance of a transverse drawing machine, leaving a longitudinal drawing machine. This device includes a fixed cylinder with an axis perpendicular to the travel axis of the film, located upstream of the entrance to the transverse drawing machine, whose lower generatrix is located in the film travel plane in the transverse drawing machine, a chest whose axis is perpendicular to the travel axis of the film, mounted on a movable support, so that it can be displaced between a retracted position and a position in which the chest is located between the fixed cylinder and the entrance to the transverse drawing machine, the upper surface of the chest then being disposed substantially in the plane in which the film travels in the transverse drawing machine. The chest serves to accommodate at least one retractable knife, displaceable in the direction of the chest axis and two lifters each associated with a reversing pulley of the transverse drawing machine, which are displaceable between a lower position and a position in which they are located in the plane of travel of tenters that grip the film.
