FIG. 7 is a view showing a state of being stuck, and FIG. 7 is an enlarged view of a main part thereof.

First, the cord-shaped rubber 9 cut to a fixed size (width and length) is opened on the side of the release paper 11 and the side of the release margin 12 is opened by an arm means (not shown) at the opening hole 101b of the spiral roll 101. Approach to. At this time, the spiral roll 101 is in the state of the initial position shown in FIG. 1, and the opening hole 101b is controlled to be positioned at the upper part as shown in FIG. 4 at the initial position. Since the opening hole 101b is sucked by the vacuum means (not shown) through the vacuum tube 102a, the cord-shaped rubber 8 brought close to the opening hole 101b is adsorbed by the opening hole 101b. The servo motor 105 starts to rotate at the time when it is adsorbed, and the spiral roll 101 shows an arrow A.
Start rotating in the direction. At this time, the peeling allowance 12 is the peeling plate 1
Since the release paper 11 is peeled from the surface of the adhesive 10 because it is caught by 07, the cord-shaped rubber 8 is wound around the spiral roll 101 along the spiral groove 101a. At this time, the adhesive application surface is on the outer peripheral side. Simultaneously with the rotation, the spiral roll 101 advances in the arrow B direction by the screw structure of the shaft 102 (FIG. 2).

The cord-shaped rubber 8 is previously attached to the endless belt 111.
Is cut to the length of the inner circumference of the spiral groove 10

Next, the elevating cylinder 114 operates and the spiral roll 101 and the attaching roll 108 descend, and the attaching roll 108 descends to a point where the inner peripheral surface of the endless belt 111 is pressed with a predetermined pressure. At this time, the winding start end of the string-shaped rubber 8 is delivered from the spiral roll 101 to the pasting roll 108 side in parallel. This is because the spiral roll 101 is provided in the groove 108a of the sticking roll 108.
Since the opening hole 108b similar to the opening hole 101b is formed and is sucked by the vacuum means (not shown), the starting end of the cord-shaped rubber 8 is delivered by being sucked to the opening hole 108b side. Here, the spiral roll 101, the attachment roll 108, and the endless belt 111 are rotationally driven by synchronous control.

The string-shaped rubber 8 delivered to the attaching roll 108 is attached to the attaching roll 10 as shown in FIGS. 6 and 7.
8 is pressed against the inner peripheral surface of the endless belt 111, the adhesive surface of the string-shaped rubber 8 sticks to the inner peripheral surface, and the string-shaped rubber 8 is rotated from the spiral roll 101 to the inside of the endless belt 111 by the rotation of the endless belt 111. It is attached to a predetermined position on the peripheral surface.
Since the string-shaped rubber 8 is cut to the length of the inner circumference of the endless belt 8 in advance, one string (one rotation) of the endless belt 111 completes the attachment work of one string-shaped rubber 8. After the end, the elevating cylinder 114 is actuated, the attaching roll 108 is separated from the inner peripheral surface of the endless belt 111, and the advancing cylinder 115 advances the attaching roll 108 until the attaching roll 108 reaches the other end side attaching point of the endless belt 111. When the other end attachment point is reached, the spiral roll 101 is returned to the initial position, and the attaching operation of the cord-shaped rubber 8 is executed again. In this manner, the cord-shaped rubber 8 for preventing the meandering is attached to both inner peripheral ends of the endless belt 111 by the automatic machine.

In the present embodiment, the endless belt is applied to the photosensitive belt and the intermediate transfer belt, which are used in the electrophotographic image forming apparatus, and the string-like rubber for preventing the meandering is attached to both end surfaces of the inner circumference. Although the case has been described as an example, it is obvious that the present invention is not limited to these applications, and needless to say, the present invention can be applied to all the methods of sticking a string-shaped member having an adhesive applied to one surface to another object. .
