    • A tape-applying apparatus (10) is advanced toward a body (15) upon which a strip of tape (16) is to be applied to urge a plurality of stitching rollers (72, 74) against the body (15). Further advancing of the apparatus (10) will move an applicator roller (42) and the end of the tape (16) into engagement with the body (15). As the body (15) is moved past the tape applying apparatus (10), the tape (16) is pulled over the applicator roller (42) and is stitched to the body (15) by the stitching rollers (72, 74). When sufficient tape (16) has been applied, the housing (20) of the tape-applying apparatus (10) is urged away from the body (15) which moves the applicator roller (42) out of contact with the body (15). A brake apparatus (94) on the housing (20) is activated by a cam recess (80) on the holders (50) for some of the stitching rollers (72). The brake apparatus (94) engages the applicator roller (42) to arrest further feeding of tape (16) to the body (15). Continued rotation of the body (15) with some of the stiching rollers (72) in contact therewith will stretch the tape (16) between the applicator roller (42) and the stitching rollers (72) until the tape (16) is severed. The free end of the tape (16) is left in position on the applicator roller (42) ready for the next application to the same or a different body (15).
    • 带施加装置(10)朝向主体(15)前进,在主体(15)上施加带(16),以将多个针迹辊(72,74)推压到主体(15)上。 装置(10)的进一步推进将使施加辊(42)和带(16)的端部移动成与主体(15)接合。 当主体(15)移动通过胶带涂布装置(10)时,胶带(16)被拉过涂布辊(42),并通过缝合辊(72,74)缝合到主体15。 当已经施加足够的带(16)时,带施加装置(10)的壳体(20)被推离离开施加辊(42)脱离与主体(15)接触的主体(15) 。 壳体(20)上的制动装置(94)由用于一些缝合辊(72)的保持器(50)上的凸轮凹部(80)启动。 制动装置(94)接合施加辊(42)以阻止带(16)进一步进给到主体(15)。 主体(15)随着与其接触的一些打桩辊(72)的继续旋转将使施加辊(42)和缝合辊(72)之间的带(16)伸展直到带(16)被切断。 带(16)的自由端被放置在施加辊(42)上就位以准备下一次施加到相同或不同的主体(15)上。
