After that, the cutting means 70 drives the linear motion motor 71 and the linear motor 75 to raise the cutting blade 76 as shown by a two-dot chain line in FIG. 2A, and then the cutting blade 76 is moved along the groove 78B. To move back and forth. Thereby, original fabric RS1 is cut | disconnected and rear-end part RS1R is formed in original fabric RS1, as shown to FIG. 2 (B). Thereafter, the cutting means 70 drives the linear motion motor 71 to lower the cutting blade 76.

  Next, the feeding means 40 drives the rotation motors 42 and 45A and, as shown in FIG. 2B, winds the original fabric RS1 separated from the rear end portion RS1R around the support roller 20, and then rotates the rotation motor. The driving of 42 and 45A is stopped. Thereafter, the feeding means 40 drives the linear motion motor 48, and as shown in FIG. 2B, the table 49 is raised so that the leading end RS2F of the original fabric RS2 is adjacent to the rear end portion RS1R of the original fabric RS1. Then, the connecting means 80 drives the rotation motor 73 and the linear motor 71, and as shown in FIG. 2B, the connection tape CT is attached to the rear end portion RS1R of the original fabric RS1 and the front end portion RS2F of the original fabric RS2. After facing each other, the holding plate 81 is raised.
