A first form of slidable arrangement mentioned here comprises the way the guide rail cooperates with a slide or roller fixed under the left and right web bases 1, 1. The second form that sets up slidable is for adopting linear guide driven mode, and linear guide is current ripe structure, through motor drive, and at this moment the motor can also be controlled through connecting the PLC controller, can break away from artifical manual promotion completely, and is more laborsaving.

When the double-sided adhesive tape 19 of the next layer is needed to be used, the tearing tab 22 is pulled (at B), the second nick 21 of the second layer is pulled to be pulled away, the second anti-sticking unit 18 is torn along the first nick 20 between the second layer and the third layer, and the tearing tab 22 of the third layer is connected to the bottom surface of the third anti-sticking unit 18 and therefore cannot be torn (the tearing tab of the third layer in fig. 4 is blocked).
