摘要： There is provided an unspooling assembly capable of tensioned dispensing of a material (9) to a knitting machine during a knitting process, the unspooling assembly comprising: a variable motor drive assembly (36) comprising: a motor configured to be coupled to a material package (28) and to rotate the material package during the knitting process; a variable motor drive coupled to the motor and configured to drive the motor: in a first rotational direction at a plurality of speeds; and in a second rotational direction; a roller guided stop motion assembly comprising: roller guides (48, 52, 54, 55) for guiding the material (9); spring arm (29); and a spring arm trigger sensor (29). The spring arm (29) and spring arm trigger sensor (29) are configured to: sense various tensions of the material (9) during rotation of the motor when a first position of the spring arm (29) is sensed by the spring arm trigger sensor (29); and reposition the spring arm (29) to one of a plurality of predetermined positions that corresponds to a tension of the material (9). The unspooling assembly further comprises a controller coupled to the variable motor drive and the roller guided stop motion assembly and configured to: receive a first signal from the spring arm trigger sensor (29), wherein the first signal is indicative of the one of the plurality of predetermined positions of the spring arm (29); and generate a second signal for supply to the variable motor drive in response to receipt of the first signal indicative of the position of the spring arm (29), wherein the second signal indicates a selected speed of the plurality of speeds. The variable motor drive is further configured to, in response to receipt of the second signal, adjust the motor to the selected speed and rotational direction to rotate the material package (28).

摘要： A flat knitting machine that contactlessly supplies electrical power to moving bodies of the flat knitting machine is provided. The flat knitting machine includes needle beds in which multiple knitting needles are arranged side-by-side, and moving bodies 2 that are involved in the knitting of a knitted fabric by traveling along a rail 1R. This flat knitting machine includes: a primary coil 31 that is connected to a power supply of the flat knitting machine and has an axis that is held parallel with the axis of the rail 1R; a tubular member 34 that is provided on each of the moving bodies 2, the primary coil 31 passing through the tubular member 34; a secondary coil 32 that is wound around the tubular member 34 and receives electrical power from the primary coil 31 through electromagnetic induction; a control circuit 20 that is provided on each of the movingbodies 2 and is connected to the secondary coil 32; and at least one electrical device 6 that is provided on each of the moving bodies 2 and operates under control of the control circuit 20.

摘要： An object of the invention is to be provide a yarn feeding apparatus of a flat knitting machine capable of accurately predicting a required amount of a knitting yarn and knitting a fabric while supplying knitting yarn necessary for knitting. The knitting yarn is fed out based on an idea shown in a solid line in consideration of a yarn speed corresponding to the requirement for knitting yarn produced according to the movement of a yarn feeding member as shown by chain lines in Fig. 6 (b). A knitting yarn is stored on a buffer rod at a start of knitting because the speed of a motor such as a servo motor for feeding a knitting yarn lags behind the yarn speed. A knitting yarn that runs short at the time of deceleration at an end of knitting is also fed out in advance.
摘要翻译： 本发明的目的是提供一种横编机的喂纱装置，能够准确地预测针织纱的所需数量并编织织物，同时提供编织所需的针织纱线。 考虑到与图1中的点划线所示的喂纱部件的运动所生成的针织纱线的要求相对应的纱线速度，以实线示出的想法，进行针织纱的送出。 6（b）。 针织纱在开始编织时存储在缓冲杆上，因为诸如用于喂入针织纱的伺服电动机之类的电动机的速度滞后于纱线速度。 编织结束时的减速时间短的针织纱也预先送出。
