On the other hand, as shown in FIG. 4, when the core 24A is rotated counterclockwise, the left portion of the core 24A is located on the upstream side, so that the film 16 is wound in the counterclockwise direction. Needs to guide the leading end of the film 16 to the left side of the core 24A. For this reason, a film guide device 50 that guides the film 16 to the left side of the core 24A is provided above the winding device 28.

The film guide device 50 has a guide plate 52 for guiding the conveyed film 16. The guide plate 52 moves forward and backward with respect to the transport path of the film 16 by a link mechanism 56 driven by a cylinder 54, and a swingable guide plate 53 is provided at a leading end thereof. The guide plate 53 is connected to a motor (not shown), and is driven by the motor to swing the distal end of the guide plate 52.

On the other hand, the link mechanism 56 is composed of two arms 58 and 60 rotatably supported at one end near the upper end of the guide plate 52.
The other end 8 is fixed to a support shaft 62 rotatably supported by the main body frame of the winding device 10. A cylinder 54 is connected to the support shaft 62 via an auxiliary arm 63.

2 protrudes from the film transport path. A guide plate 53 further projects from the tip end of the guide plate 55 projecting from the film transport path, and the guide plate 53 guides the film 16 transported from above to the left side of the core 24A.

The operation of the embodiment of the belt-shaped material winding device according to the present invention configured as described above is as follows. First, a film 1 produced by an extruder (not shown)
6 is introduced into the winding device 10, which is performed as follows. The guide rollers 20, 20,... Disposed on the film transport path of the winding device 10 have gears fixed to both ends (not shown), and each gear is indicated by a broken line in the figure. An endless chain 68 is wound. The chain 68 rotates along the film transport path by manually turning a handle 70 provided on the main body frame of the winding device 10. A horizontal bar 72 is stretched over a chain 68 provided on both sides of the guide roller 20.
The horizontal bar 72 is turned by turning the handle 70 and
, And travels along the film transport path.

First, a core 24B around which an introduction sheet 74 for introducing the film 16 is wound is mounted on a mounting portion on the standby position side of the biaxial turret type winder 22.
Then, the introduction sheet 74 is pulled out from the core 24 </ b> B and wound around the horizontal bar 72. Next, the handle 70 is turned, and the horizontal bar 72 around which the introduction sheet 74 is wound is caused to run backward along the transport path of the film 16. Then, when the introduction sheet 74 is conveyed to an opening (not shown) formed on the right side of the film conveyance device 10 in the drawing, the introduction sheet 74 is cut off from the horizontal bar 72, and the operator moves to the extruder. Pull it out and connect it to the generated film 16.
