DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the contents of the present invention will be described. As shown in FIG. 3, the adhesive tape 2 is placed at an appropriate interval position in the longitudinal direction of the long filament 1, which is fed in the direction of the arrow and travels, and is perpendicular to the traveling direction of the long filament 1. It is a method and an apparatus for performing feeding and sticking in a direction.

As shown in FIG. 2, the elongated filament 1 is sent out from the delivery bobbin 3 and wound up on the winding bobbin 8. Two sets of pinch rolls 4 and 6 are provided on the way, and the position of the sticking portion is placed between the pinch rolls 4 and 6.
Dancer roll devices 5 and 7 are arranged between the pinch roll 4 and the attaching section and immediately downstream of the pinch roll 6, respectively. The dancer roll devices 5 and 7 are, of course, devices for storing the long filaments 1 or for discharging the long filaments 1, and are temporarily used for attaching the adhesive tape 2.
Is stopped, it is not necessary to stop the rotation of the original sending bobbin 3 or the winding bobbin 8 at the terminal end.

Next, the apparatus of the present invention will be described with reference to FIG. The block A rotatably supports an adhesive tape bobbin 10 for supplying the adhesive tape 2 and a feed roll 11 located immediately downstream of the adhesive tape bobbin, and extends on the same rail (not shown) as the block B located on the right side thereof. It is driven forward and backward in a direction orthogonal to the running direction of the shawl strip 1. The block A is moved by the hydraulic cylinder 9, and when the block is driven to the right, the block B is also pushed out via the cutting origin setting screw 12.

Limiting the rightward movement distance is an adjustable stopper 14 located on the right side of the block B, so that the feed depth of the end P of the adhesive tape 2 to the right in FIG. That is, the width of the adhesive tape on the elongated filament 1 is determined.

The block B has a vacuum suction block 1.
3, the cutter 15 and the attaching roll 18 (this is attached to the tip of one arm rotatably attached to the attaching roll attaching body 17 and rolls the adhesive tape 2 on the surface of the elongated filament 1 A fluid pressure cylinder 16 or the like for pressing downwardly a roller for rubbing the pressure-sensitive adhesive tape 2 onto the long filament 1 sufficiently strong is carried.

The suction block 13 and the cutter 15 are both driven up and down by a hydraulic cylinder 19. In FIG. 1, the suction block 13 is shown in an up state. The lower position is where the adhesive tape 2 comes into contact with the upper surface of the elongated filament 1, and the pressing force by the fluid pressure cylinder 19 does not act any more due to the stopper present on the back side which is not visible in FIG. 1. The force for pressing the adhesive tape 2 after the stopper action against the elongated filament 1 is given by a pressing spring 22.

The cutter 15 is also the same hydraulic cylinder 19
However, in the position shown by the solid line in FIG. 1, the position is also blocked by the above-mentioned stopper, and cannot move downward beyond the position in FIG. When the block B, that is, the suction block 13 is moved leftward by the fluid pressure cylinder 21 to the position indicated by the broken line, the cutter 15 comes off the above-mentioned stopper, and at this time, the cutter 15 can be lowered so that the adhesive tape 2 can be cut off for the first time. The right end line of the cutter 15 corresponds to the cutting position in FIG.

The elongated filament 1 travels on the filament suction plate 20 in a direction perpendicular to the plane of the drawing, and can be fixedly stopped on the filament suction plate 20 by the action of evacuation. Of course, at this time, the pinch roll 6 shown in FIG. 2 is stopped by an appropriate sensor (not shown) for sensing the sticking position. By the way, the pinch roll 4 is a dancer roll device 5
The rotation is driven and stopped by sensing the stored amount of the liquid.

Next, the steps of the method of the present invention will be described. As described above, when the position where the adhesive tape 2 is to be applied is sensed and the elongated filament 1 is temporarily stopped, the fluid pressure cylinder 9 is stopped.
Are moved to the right together with the blocks A and B until they hit the stopper 14. At this time, the suction block 13 sucks the upper surface of the adhesive tape 2, and conveys the adhesive tape 2 to the right together with the bobbin 10 as its supply source, and the edge P coincides with the edge of the elongated filament 1. To the desired position (although this position can be set to the desired position). The above operations are performed simultaneously,
Alternatively, the standby for the adhesive tape 2 may be performed first.

Next, the suction block 13 is lowered by the operation of the fluid pressure cylinder 19 and is pressed onto the surface of the long filament 1. Thus, the adhesive tape 2 is in a temporarily fixed state. Thereafter, the fluid pressure cylinder 9 is operated to move only the block A to the left. At this time, the pressure-sensitive adhesive tape 2 is fed by a length necessary for suction by the action of the feeding roll 11. The length of the adhesive tape 2 for one use is determined by the protruding length of the cutting origin setting screw 12.

Then, while the evacuation of the suction block 13 is stopped and raised upward, the fluid cylinder 16 is operated to lower the sticking roll 18 to a position where the upper surface of the adhesive tape 2 is pressed. Then, it is moved to the left until it hits the tip of the interval setting screw 12. This position is shown by a broken line in FIG. 1, and the adhesive tape 2 is completely rubbed on the surface of the long filament 1 by the rubbing roll 18 in the process of the leftward movement. Thereafter, the application roll 18 is raised.

The adhesive tape 2 is cut by lowering the cutter 15 at the broken line position of the suction block 13. At this time, the suction block 13 is simultaneously lowered to a position in contact with the upper surface of the adhesive tape 2, and the valve is switched to a vacuum state so that the next time the adhesive is absorbed. Then, the suction block 13 is raised to the position indicated by the broken line in FIG.

Since the above-mentioned method is a problem of simple sequence control of each step, it can be easily automated as a whole. The operations of the suction block 13 and the cutter 15 may be performed by separate fluid cylinders.

In the above-described method of the present invention, the sticking operation is performed while the flow of the long filament 1 is stopped temporarily. It is also easy to perform the sticking operation while running the entire apparatus 1 at the same speed as the long filament 1.

[0021]

According to the present invention, the striated suction plate fixes the running long striate stationary, and the suction block sucks the leading end of the adhesive tape and moves up to the long striated body. The pressure-sensitive adhesive tape is pressed from above, and the adhesive roll is further rubbed and adhered to the long striatum, and the block A is retracted by itself and the adhesive tape for one time is fed out. Has an effect that the adhesive tape can be automatically attached with a desired interval in the longitudinal direction of the long filament running on the adhesive tape by a series of operations such as cutting the adhesive tape at a predetermined position, and there is an advantage that the power saving effect is also large. .
