Specifically, if "the tape head 3 and the soft nip 19 reach the target position a at the same time and assist the winding at a constant speed V", two conditions need to be satisfied, see below:
the first condition is that: when the tape head 3 starts to shield the light beam of the tape head detection photoelectric switch a '16, the recoiling machine 4 drives the rubber sleeve 5 to rotate, so that the time period used by the tape head 3 from the tape head detection photoelectric switch a' 16 to the target position a must be equal to the time period used by the rubber sleeve 5 from the initial position (thin tape starting position B/thick tape starting position C) to the target position a;
the second condition is that: when the soft jaw 19 reaches the target position a, the rotation speed of the rubber sleeve 5 must be the same speed V as the tape head 3.
For convenience of explanation and verification of the apparatus for removing a leading print according to the present embodiment, the third, fourth, and fifth embodiments are specifically applied.
In the following embodiments, a rubber sleeve having a diameter of 610mm, L is 1075mm, and L is a position where the tape head 3 initially blocks the emitted beam of the photoelectric switch a' 16 from the tape head to reach the target position a at the speed V.
