    • An overlock stitch is formed by sewing machine (11 fig. 1) into a work product (34) and the work product is accelerated away from the sewing machine so as to stretch the thread chain (Fig. 5). The stretched thread chain is cut by cutter (40), and the leading thread chain (43) recoils back toward the hollow chaining tongue (21) and is drawn into the chaining tongue by the stream of air (26) created by vacuum canister (52 Fig. 6). The next work product draws the leading thread chain out of the hollow chaining tongue and the sewing machine captures the leading thread chain in the stitch. Transfer conveyor (15 Fig. 1) moves the work product (34) into alignment with everter tube assembly (106), grippers (109 and 110) grip and open one end of the work product (Figs. 9-14), and air drawn through the everter tube assembly everts the work product. The gripper tube assembly opens along its lower portion (Fig. 16) and drops the work product.
    • 通过缝纫机(图1)形成工作产品(34)并将工件从缝纫机加速离开以拉伸线链(图5)。 拉伸的线链由切割器(40)切割,并且前导线链(43)朝着空心链舌(21)回弹,并被真空罐(26)产生的空气流(26)拉入链舌 52图6)。 下一个工作产品将引导线链从中空链接舌中拉出,缝纫机捕获针迹中的前导线链。 传送带(15图1)将工件(34)移动到与更长的管组件(106)对准,夹具(109和110)夹紧并打开工件的一端(图9-14)和空气 通过不断的管组件吸收工作产品。 夹具管组件沿其下部开口(图16),并丢弃工件。
