ことなく帯状材を交換して繰り出せる。One of the pressing rollers is moved to the feeding roller side, and the strip material is sandwiched. By the normal rotation of the feeding roller, the strip material is supplied to the feeding path, and the feeding roller and the other pressing roller separated from the roller are fed. After waiting for the start end of the strip material remaining during the detection, the detection sensor detects that the remaining amount of the strip material being fed is reduced, and after cutting the end portion of the fed strip material with a cutter, The control unit moves the pressing roller on the standby side to the feeding roller side to make contact therewith, and at the same time, by rotating the feeding roller in reverse, the end portion of the strip-shaped material that has been fed is pulled out from the feeding path. Since the waiting band is continuously supplied to the payout path, the end of the remaining band is automatically removed and the band is replaced without bonding the end and the beginning of the band with the adhesive tape.

けるから、交換作業が簡単になる。Therefore, compared with the conventional one in which the ends of both strips are joined by an adhesive tape and replaced, the joint of the two strips joined by the adhesive tape is not supplied to the pay-out path, so that it is troublesome to eliminate this in the subsequent process. This eliminates the need for an elimination mechanism and eliminates the need for a connection cutter or connection mechanism, which simplifies the structure. In addition, each time a replacement is made, an adhesive tape is attached to the tip of the spare-side strip. This eliminates the necessity and eliminates the trouble of removing the end of the remaining strip-shaped material, thereby simplifying the replacement operation.

機構。1. An unloading path (4) and two transfer paths (3, 3).
The reel holding part (1,1) is provided on each upstream side via
A strip material reel (2) having a strip material (2a) wound thereon is detachably held in each of the reel holding portions (1, 1), and both ends are detected by the detection sensor (1a) by detecting the end of the strip material (2a). In the strip material exchange mechanism of the strip material supply device for supplying the strip material (2a) from the reel holding unit (1,1) alternately to the payout path (4) via the respective transfer paths (3,3), The end of one of the transfer paths (3, 3) and the entrance of the feed-out path (4) are arranged in a three-pronged manner, and a feed-out roller (5a) rotatable in both forward and reverse directions is arranged at the intersection. On both transfer paths (3,3) side of the outer periphery of the feeding roller (5a),
Extruding rollers (5b, 5b) are respectively provided so as to be able to move toward and away from each other with the strip-shaped material (2a) interposed therebetween, and the strip-shaped material (2a) based on the output from the detection sensor (1a).
A cutter (4a) for cutting the feed roller (5) is disposed in the feed path (4), and after the cutter (4a) operates, the feed roller (5) is cut.
a) The pressing roller (5b) on the standby side, which is farther away, is moved toward the feeding roller (5a) to be brought into contact therewith, and at the same time, the feeding roller (5a) is rotated in the direction opposite to the previous rotation direction, A strip material exchange mechanism for a strip material feeding device, further comprising a control unit for moving the other extrusion roller (5b) away from the feed roller (5a) after a predetermined time.
