Abstract: The device (2) comprises four drawing cylinders (6, 7, 8, 9) on which the film (5) passes and which are associated with press cylinders (13, 21, 26), comprising: a first drawing cylinder (6) having a fixed axis (10), a second drawing cylinder (7) having a fixed axis (12) which is offset in relation to the previous one, a third drawing cylinder (8) whose position is adjustable and a fourth drawing cylinder (9) having a fixed axis (25). Said cylinders (6 A 9) are rotationally driven at differentiated speeds, such that a first drawing stage is formed between the second cylinder (7) and the third cylinder (8), whereby the drawing distance (D) is preferably adjustable, and a second drawing stage is formed between the third cylinder (8) and the fourth cylinder (9). The invention is used for the longitudinal drawing of synthetic films.

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.
