When the detection rod 5 rolls on the top and lands on the rollers 4, 4, the detection rod 5 rotates greatly as shown by the solid line in FIG. rotates clockwise as shown by the solid line in Figure 2,
The tail detection position moves to A. The paper on the table 2 is gradually wound up by the rotation of the rollers 4, 4, and when the tail passes through A, the tail detector 3 detects the passage of the tail and transmits a signal to the electric control device. When the electric control device receives the signal, it starts the timer means and stops the first drive source 8 after a certain period of time has elapsed. What is the fixed time set in the timer means?
This is the time from when the tail detector 3 detects the tail of the paper until the tail reaches a predetermined position at the upper end of the paper, and is determined by the rotational speed of the rollers 4, 4. Therefore, when a certain period of time has elapsed since the tail detector 3 detected the tail and the electric control device stops the operation of the first drive source 8 and stops the rotation of the rollers 4, the tail of the paper wrapper is detected. It stops at a predetermined position at the top end.

The rear detector 3 is connected to the second
Rotate slightly as shown by the chain line in the figure, and set the detection position to A.
Move to B, which is further away than . Then, the paper on the table 2 is gradually wound up by the rotation of the rollers 4, 4, and when the trailing edge passes through B, the trailing edge detector 3 detects the passing of the trailing edge in the same manner as described above, and the electric control device is activated for a certain period of time. After the elapse of time, the first drive source 8 is stopped and the rotation of the rollers 4, 4 is stopped. In this case, the trailing detector 3 detects the tail of the paper at different positions for the large-diameter wrapping paper R and the small-diameter wrapping paper R', so that the length of the paper remaining on the table 2 differs. However, since the outer circumference of the wrapping paper R' is shorter than the outer circumference of the wrapping paper R, when the rollers 4, 4 rotate for a certain period of time after detecting the tail of the paper,
The trailing end rises to a predetermined position at the upper end of the wrapping paper R' and stops. In other words, if the rollers 4 and 4 are rotating at the same speed, the length of the paper roll R from the position A where the tail of the paper is detected to the upper end position A' of the paper roll R when this tail is wound. , rolling paper
At R', the top end position of the paper roll R' when this tail is wound from position B where the trailing paper is detected.
The length up to B' becomes equal.
