Abstract: A sewing machine control device performs a closed loop control of an induction motor without using an encoder for detecting the motor speed. The control device includes an inverter for driving the induction motor, and controls the inverter output so that the actual speed of the motor is brought into coincidence with a target speed instructed from a speed instruction device. When the control device executes the inverter control, it uses not only the target speed fed from the speed instruction device but also a detection signal generated from a needle position detector that represents the position of a needle bar and the moving speed thereof.

Abstract: A sewing system includes a plurality of sewing machines and a managing apparatus for managing sewing operations of the sewing machines. The managing apparatus determines a type of a work to be sewn by each of the sewing machines and sewing steps for such work, and supplies an identification code thereof to the sewing machines. A controller of the sewing machine reads out sewing data corresponding to the identification code from sewing data storage, and controls the sewing machine in accordance with the sewing data.

Abstract: A sewing machine with a cloth-edge detector has a light source for casting light on a sensing point on a cloth, and a light receiver for generating an intensity signal according to the intensity of the received light. Before sewing, a reference signal is set at an average of two intensity signals that are gauged before and after a cloth edge. The cloth edge can be detected by comparing the intensity signal from the light receiver with the reference signal.
Abstract translation: 具有布边检测器的缝纫机具有用于在布上的感测点上投射光的光源和用于根据所接收的光的强度产生强度信号的光接收器。 在缝制之前，将参考信号设置为在布边之前和之后测量的两个强度信号的平均值。 可以通过将来自光接收器的强度信号与参考信号进行比较来检测布边。

Abstract: A sewing machine forms a seam in the form of a series of stitches for a length preset by the operator. The length of the seam formed is computed from feed pitches data each generated when one stitch is formed. The operation of the sewing machine is stopped when the computed seam length coincides with the preset seam length.
Abstract translation: 缝纫机以一系列针迹的形式形成接缝，长度由操作员预设。 形成的接缝的长度是由一个缝合形成时的每个进给间距数据计算的。 当计算出的接缝长度与预设接缝长度重合时，缝纫机的操作停止。

Abstract: The invention relates to a sewing machine provided with a needle reciprocated according to rotations of a main shaft and work feeding devices actuated synchronously with rotations of the main shaft, setting a margin to sew from a trailing edge to a sewing end position. The sewing machine includes devices for computing a terminal stitch length according to a set margin width. Control devices are provided for controlling a sewing to be carried out for coping with that which corresponds to the terminal stitch length computed by the computing device. The sewing machine further comprises computing devices for applying a correction to at least one of a number of stitches and a feed pitch, as occasion demands, where there arises the remainder as the result of an operation of the computing devices, and control devices for controlling the sewing to be carried out according to the computed result.
