摘要： An auxiliary transport device for sewing machines utilized to attach bands to the edge of a workpiece having a pair of spaced roller members disposed in frictional engagement with a band attached to the workpiece and simultaneously rotated incrementally for advancing the workpiece away from the sewing zone. A compensating roller is mounted co-axial with one of the pair of spaced roller members and incrementally rotated therewith in a location to frictionally engage and advance that portion of the workpiece extending from the band. The compensating roller is capable of yielding in a vertical direction without effecting the position of the roller with which it is operatively associated and provides a means for effectively accommodating portions of the workpiece varying in thickness as a result of attachments such as loops, pockets and the like.

摘要： A thread-cutting device for a sewing machine comprises a rigid casing fixed on one edge of the working surface of the sewing machine in a position adjacent to the fabric being sewn. A discharge tube extends from one end of the casing to a suction mouth located on the other end of the casing and faces the fabric being sewn. A blower apparatus is supplied with compressed air and comprises at least one vent located in the mouth and is designed to direct the compressed air along the discharge tube. A pivotable cutting element is mounted in the region of the suction mouth. A control element is fixed to the casing and has a rod shaped portion passing across the suction mouth which can be positioned in a plurality of reference notches located on the outside of the casing. The reference notches are arranged in accordance with the types of fabric to be sewn and are designed to position the rod-shaped portion in a direction substantially perpendicular to the feed direction of the fabric being sewn.
摘要翻译： 一种缝纫机的切线装置，其特征在于，包括：刚性壳体，其与缝制的织物相邻的位置固定在缝纫机的工作面的一个边缘上。 排放管从壳体的一端延伸到位于壳体另一端的吸嘴，并面向被缝制的织物。 鼓风机装置被供给压缩空气，并且包括位于口中的至少一个通风口，并被设计成沿着排放管引导压缩空气。 可枢转的切割元件安装在吸嘴的区域中。 控制元件固定在壳体上，并且具有穿过吸嘴的棒状部分，其可以定位在位于壳体外部的多个参考凹口中。 参考凹口根据待缝合的织物的类型布置，并且被设计成将棒状部分沿着基本上垂直于被缝合的织物的进给方向的方向定位。

摘要： A device for interrupting the formation of stitches in a sewing machine having at least two needles and a looper for each needle which are arranged to be actuated in tandem. The needles are phased to perform their functions simultaneously with a first having an elongated thread opening, and the second a conventional opening. The first needles' looper is slightly elevated and if no lack of phasing exists between the needles and their loopers, the elevated looper will cooperate with its needle adjacent the upper end of the thread hole and the other looper cooperates with its needle in a conventional manner. Should there be a lack of phasing, the elevated looper cooperates with its needle midway between the length of the thread hole which causes the other looper to pass beneath the hole of its needle thus interrupting the formation of stitches by the latter needle.
摘要翻译： 一种用于中断在缝纫机中形成线迹的装置，其具有至少两根针和每针的弯针，所述针被布置为串联地致动。 针被定相以与具有细长螺纹开口的第一个同时执行它们的功能，而第二个具有常规的开口。 第一针针刺略微升高，如果针和它们之间的针头不存在相位差，则升高的手套将与其邻近线螺纹孔的上端的针头配合，而另一个手套以常规方式与针头配合 。 如果缺乏定相，升高的斗手在螺纹孔的长度之间的中间配合，导致另一个弯针穿过其针孔的下方，从而中断由针头形成的针迹。
