When the stub end of the strip 200 is transferred to the roller member 231, the first driving source 242 drives the rotating member 242 to rotate and drives the roller member 231 to rotate, so that the strip 200 of a desired length is automatically wound around the roller member 231 with the tail of the strip left at a certain length on the support plate 20 below the bare bead 300. Here the required length of the strip 200 is detected by the encoder 13. Specifically, this step further includes the following substeps:
s21: the first driving source 242 drives the roller member 231 to be positioned to the initial position. This initial position is accomplished by the placement of the photosensor 2312 and light reflecting member described above.

where h is the thickness of the strip, r is the radius of the roller member 231, and s is a correction value obtained through debugging experience. After the slug of the strip 200 is delivered onto the roller member 231, the drive cylinder 292 drives the brush roller 293 downward to compact the slug of the strip entering the roller member 231. The pressing roller 294 also rolls the strip wound onto the bare bead 300 while winding the strip 200 onto the surface of the bare bead 200 to improve rolling quality.
The required length L of the individual beads can here be obtained by simple calculation by manually entering the parameters directly related to the length L on a screen to the control module or by manually entering the parameters directly related to the length L on a screen. The control module is a control module of the whole bead winding system and is not described in detail here.

S23: the cutting mechanism 5 cuts the tape 200 at a fixed distance upstream in the feeding direction, the length of the cut tape wound around the roller member 231 is substantially equal to the length of the tape 200 required for winding a single bead, the length of the tape 200 automatically wound around the roller member 231 is obtained as the difference between the length detected by the encoder 13 and the distance from the encoder 13 to the cutting mechanism 5 in the feeding direction of the tape 200, the distance from the encoder 13 to the cutting mechanism 5 is a known value, and the length of the tape 200 automatically wound around the roller member 231 is also obtained by the encoder 13.
S24: the first driving source 242 drives the roller member 231 to rotate continuously, and after the tail portion of the cut tape 200 wound around the roller member 231 is conveyed to the support plate 20, the roller member 231 stops rotating, and the length of the tape wound around one bead is fixed.
With the winding ring member 22 at the initial position, the bare bead 300 is inserted from the notch 221 into the inside of the winding ring member 22 until the bare bead 300 is attached to the tail of the strip on the support plate 20, and at the same time, the roller stopper assembly 48 positions the vertical state of the bare bead 300.
