Then, the adjustment section 40 inputs various dimensions of the annular product 1, the width of the tape 10a, and the winding pitch of the tape 10a around the annular product 1 through the input device 41. Calculate the length and outer circumference of product 1, and preset when the required tape length matches the tape length measured by the measuring roll 38 and when the outer circumference of product 1 and the rotational feed amount of product 1 match, respectively.

Place the annular product 1 on the product drive roll 3, and turn the handles 8, 9 in accordance with the inner diameter A, the difference B between the outer diameter and the inner diameter, and the width C of the width presser rolls 6, 6,
In addition to adjusting the positions of 7 and 7, the adjustment motor 34
to adjust the position of the flyer 11. On the other hand, the tape 10a pulled out from the roll 10 rotatably supported by the tape support shaft 10b passes through a measuring roll 38, a cutter 44, and a guide roll 46, passes through the outside of each of the plurality of bobbins, and reaches the top of the product 1. After the tip is wrapped, the drive motor 4 and fryer motor 12 are activated. As a result, the flyer 11 pulls out the tape 10a and repeats the operation of sequentially wrapping the tape 10a around the inner circumferential surface, one side surface, the outer circumferential surface, and the other side of the annular product 1 while winding it around the outer circumference, and the product drive roll 3 The product 1 is rotated at a predetermined speed, the tape 10a is wrapped around the product 1 at a predetermined pitch, and the product 1 rotates approximately one time to determine the required tape length output from the central processing unit 42 and the actual tape length measured from the measuring roll 38. When the values match in the preset counter 43a, a cutting signal is generated to cause the cutter 44 to perform a cutting operation.
The tape 10a is cut exactly to the required length, with no excess or deficiency.

Further, the central processing unit 42 calculates the outer circumference of the product 1, and the preset counter 43b receives input of the calculated outer circumference and the feed amount of the product 1 by the product drive roll 3. When both the outer circumference length and the feed rate of the product 1 match, a stop pulse signal is output, and the drive motor 4 and fryer motor 12 are stopped, thereby stopping the entire machine.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. If it is set, it is not necessary to input the width C of the product 1, and the relative position of the flyer 11 with respect to the annular product is determined, and for example, the outer periphery of the flyer 11 is rotated along the center of the annular shape of the product 1. In this case, since the outer diameter of the product 1 is detected and output as a digital signal and inputted to the adjustment section 40, it is only necessary to input the inner diameter A of the product 1, which is usually kept at a constant value. ,
In that case, there is no need to input the dimensions of the annular product again, and the adjustment section can be of an analog type instead of a digital type.

A position adjustment section that can be moved freely is provided, and the adjustment section calculates the required tape length by receiving the input of the dimensions of the annular product and the winding pitch of the tape, and calculates the required tape length and the tape length measured with the measuring roll. Outputs a cutting signal when there is a match,
By cutting the tape with a cutter at a predetermined position based on the cutting signal, it is possible to accurately cut the tape to the required length without excess or deficiency, eliminate waste of tape, and prevent a decrease in work efficiency. It has the following effects. In addition, the present invention provides a method for forming an annular product by detecting the width dimension from the position of the pair of width pressing rolls, and detecting the outer diameter dimension from a predetermined relative position of the flyer with respect to the center of the annular product. As for the dimensions of the product, the required tape length can be calculated by simply inputting the inner diameter dimension, which has the effect of further improving work efficiency.
