DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for automatically feeding and retreating a film which can be used as an emergency evacuation device between a longitudinal stretching machine and a transverse stretching tenter oven in a biaxially stretched film production line.

[0002]

2. Description of the Related Art Generally, in a biaxially stretched film production line, when a film of a material in a tenter oven for transverse stretching is fed and in a transverse stretching process, the temperature distribution in the oven is not appropriate for the film characteristics. Or, the film may not be stretched uniformly and may be torn in the vertical direction from a thinned portion due to foreign matter or the like. Therefore, in this case, the paper had to be restarted from the entrance of the tenter oven. For this reason, it is necessary to cut the supplied film just before the horizontal stretching machine, wind it up on a scrap roll, and immediately remove the film in the oven. As a conventional example of a mechanism for cutting a film between a longitudinal stretching machine and a transverse stretching machine, one shown in FIG. 11 has been proposed. That is, in FIG. 11, the normal film 3 exits from the longitudinal stretching machine 1 and is sent to the transverse stretching machine 2 through the space between the rolls 4, 5, and 6 as shown by a two-dot chain line. When there is, the film 3 is approached to the scrap roll 7 by the pass roll 9,
The film 3 supported by the pass roll 9 and the touch roll 10 is cut off by a cutter 8 having a saw blade and having a full width of the film. At the same time, the cut end of the film 3 is cut by the touch roll 10 by a scrap roll 7 (adsorption by vacuum or (A double-sided adhesive tape is applied) and the film 3 is wound up. In the conventional example shown in FIG. 11, the entire width of a thick film after longitudinal stretching is cut transversely, and it is difficult to cut, depending on the material, and cutting failure easily occurs. As a method of avoiding this problem, a method of narrowing the horizontal cutting width, cutting the film obliquely after cutting, and cutting off the entire width is disclosed in Japanese Patent Application No. Hei.
No. 148222. This will be described below.

FIGS. 6 to 10 show the latter conventional example.

Further, a double-sided adhesive tape having an appropriate width is wound around the outer periphery of the center of the scrap roll 7. Numeral 22 denotes a transverse cutter which crosses the ribbon-shaped film between two vertically cut slits when the film 3 is cut. The transverse cutter 22 is operated by an actuator 25.

Next, the operation of the automatic film winding apparatus shown in FIG. 6 will be described with reference to FIGS. FIG. 7 shows a state in which the film 3 is fed in the direction of the arrow without any trouble. However, if a trouble occurs in the process after the horizontal stretching, the actuators 23 and 24 are simultaneously operated, and the first operating arm 1 is moved.
8 and the second operating arm 19 rotate in the directions A and B about the axes X and Y, respectively, and the state shown in FIG. 8 is obtained. At this position, the cutter knife 28 pierces the film 3 to form two slits 3a in the vertical direction. Next, the scrap roll 7 starts rotating in the direction C at a peripheral speed slightly higher than the film speed. In this position, the touch roll 20 remains on the film 3 and does not yet contact the scrap roll 7. Next, the crossing cutter 22 is actuated by the actuator 25 and starts rotating in the direction of arrow D. FIG. 9 shows a state immediately after the ribbon-shaped film between the slits 3a of the film 3 is crossed by the crossing cutter 22. 3b is the film 3
