<p>An ultrasonic wave welding device (70) is disposed facing both surfaces of a fastener chain (11) at a position where a pair of reinforcing film tapes (17) pulled out from a reinforcing film tape guiding means (30) are shifted in the feeding direction of the fastener chain (11) from a position intersecting with the fastener chain (11). A gripper drive means (52) is provided with a servomotor (68) for driving a gripper (51) in the direction in which the reinforcing film tapes (17) are pulled out, and a cylinder device (61) for driving the gripper (51) in the direction of feeding of the fastener chain (11); and a reinforcing film piece (16) to be bonded next is held in a standby position (P3) while a pair of the reinforcing film pieces (16) are being bonded with the ultrasonic wave welding device (70).</p> |
