摘要： In a presser foot and a sewing machine according to the present invention, a guide hole is formed in a presser leg to which a fixed knife is attached, so as to passing through the presser leg up and down, and a knife holder is fitted and held to the guide hole. The fixed knife is inserted to a retention groove provided in a peripheral surface of the knife holder through a window hole provided in the presser leg, and is fixed by fastening a stop screw. A position of the fixed knife is adjusted in a vertical direction by moving the knife holder in the vertical direction along the guide hole and fastening the stop screw at an appropriate position, thereby changing a cut position of ends of fabrics and changing an overlapped width of the fabrics at a time of seaming.

摘要： In the case of a sewing machine having a cutting means for the purpose of cutting a workpiece edge a disengaging means is provided by means of which an upper cutter is moved out of a working position in which it moves in a reciprocating manner--in dependence upon the rotational movement of a drive shaft--into an inoperative position. In so doing a lower cutter is covered.

摘要： A grooved barrel cam is mounted on a needle bar drive shaft. As the last step, after stitching is completed and power is removed, an engaging arm inserts a follower pin into the cam. A knife cam follower lever drives a knife drive shaft and a knife driving lever. The knife driving lever drives a knife holder downward. A connector at a middle of the knife holder maintains the holder vertical. A knife is secured at the bottom of the knife holder. The cam and a tension spring angularly return the cam follower lever, the shaft and the knife lever and lift the holder, when the cut has been completed. A compression spring around the knife drive shaft moves the follower away from the cam once the engaging arm has released the follower. Engaging the knife cam follower and operating the knife driving mechanism on the last revolution after the clutch is released helps exhaust the kinetic energy of the sewing machine before bringing the machine to a stop.

摘要翻译： 带槽的镜筒凸轮安装在针杆驱动轴上。 作为最后一步，在缝合完成并且电力消除之后，接合臂将从动销插入凸轮。 刀凸轮从动杠杆驱动刀驱动轴和刀驱动杆。 刀驱动杆向下驱动刀架。 刀架中间的连接器保持支架垂直。 刀被固定在刀架的底部。 当切割完成时，凸轮和拉伸弹簧有角度地返回凸轮从动杠杆，轴和刀杆，并抬起支架。 一旦接合臂释放跟随器，围绕刀驱动轴的压缩弹簧就使离合器远离凸轮。 在释放离合器之后，最后一圈旋转刀凸轮从动件和操作刀驱动机构有助于在使机器停止之前排出缝纫机的动能。

摘要： A device for sewing together two plies of cloth with a lap seam. The device comprises a cloth guide that is disposed between a plurality of reciprocating needles and the front of a cutting knife. The guiding portion of the cloth guide extends substantially between the needles and the front edge of the cutting knife. A cloth guide for assuring a full lap of material when sewing a lap seam where the left ply is to be laid on top of the right ply is also provided.

摘要： A cutting device for an automatic sewing machine, including a knife (2) and a knife guard (3) which projects the fingers of the operator. The knife (2) is capable of being lowered to a cutting area in a cutting plane (S) only when the knife guard (3) is in its protecting position. The knife (2) and knife guard (3) are driven simultaneosuly by a single drive, the knife guard (3) reaching the cutting plane (S) earlier than the knife (2). If the knife guard (3) cannot substantially reach its protective position, then the downward movement of the knife (2) is mechanically blocked, preventing further movement of the knife (2). This mechanical blocking is carried out by the coaction of a lever (20) which is connected to the knife guard (3) by a connecting member (21), the lever (20) being moveable in translation and rotation, and by a lever (19), which is moveable rotationally only and has a stop (37) thereon for blocking movement of the knife (2) when the knife guard (3) is not in its protective position. The stop (37) is responsive both to the drive (5) and to the degree to which the knife guard (3) has been lowered.

摘要翻译： 一种用于自动缝纫机的切割装置，包括一个将操作者的手指伸出的刀（2）和刀架（3）。 仅当刀保护罩（3）处于其保护位置时，刀（2）能够在切割平面（S）中被降低到切割区域。 刀（2）和刀架（3）由单个驱动器同时驱动，刀保护装置（3）比刀（2）早到达切割平面（S）。 如果刀架（3）基本不能到达其保护位置，则刀（2）的向下运动被机械地阻挡，从而防止刀（2）进一步移动。 这种机械阻塞通过连接构件（21）连接到刀架（3）的杠杆（20）的协同作用，杠杆（20）能够平移和旋转并且通过杠杆（ 19），其可旋转地移动并且在其上具有止动件（37），用于当刀防护件（3）不处于其保护位置时阻止刀片（2）的移动。 止动件（37）对驱动装置（5）和刀保护装置（3）的降低程度都有响应。

摘要： A trimming pressure foot that can be interchangeably attached to a sewing machine includes one scissors blade fixedly attached to a pressure foot and one scissors blade pivotable about a shaft. The cutting motion is derived from the up-and-down motion of a needle drive rod. To this end, a pivot lever which is essentially in the shape of an inverted T is used. The pivot lever is pivotable about a shaft connected to the pressure foot, and its upwardly protruding arm rests with spring pressure on a needle securing screw. A flank of the arm resting on the screw forms an acute angle with the path of motion of the needle drive rod. In operation of the sewing machine, the up-and-down motion of the needle drive rod is converted into a pivoting motion of the pivot lever. The pivoting motion of the lever is transmitted onto the pivotable cutting blade by a tang secured to the pivot lever and by engaging the inside of a slit of the blade. The long needle drive rod stroke is thus elegantly and simply translated into a much shorter stroke of the trimming pressure foot.

摘要翻译： 可互换地连接到缝纫机的修剪压脚包括固定地连接到压脚的剪刀刀片和可围绕轴枢转的一个剪刀刀片。 切割运动源自针驱动杆的上下运动。 为此，使用基本上呈倒T形的枢轴杠杆。 枢转杆可围绕连接到压脚的轴线枢转，并且其向上突出的臂以弹簧压力固定在针固定螺钉上。 靠在螺丝上的臂的侧面与针驱动杆的运动路径形成锐角。 在缝纫机的操作中，针驱动杆的上下运动转换成枢转杆的枢转运动。 杠杆的枢转运动通过固定到枢转杆上的柄并通过接合叶片的狭缝的内部而传递到可枢转切割刀片上。 因此，长针驱动杆行程被优雅地简单地转换成修剪压力脚的短得多的行程。

摘要： The present machine is for affixing binding tapes to articles and including attachments for such machines which allow the machine to be run either manually or automatically. In the automatic position of the attachments, they start the machine, upon presentation of a workpiece to the machine, cut the tape at the start and finish of the work through a piston driven sheartype cutter having a driven blade cooperating with a fixed bar supporting the tape and stop the machine automatically. Also the operator can run the machine manually and stop the machine at any time when running the machine in said automatic position of the attachments.
