摘要： A method and apparatus for detecting an improper stitch for a Class 400 chainstitch sewing machine. A monitor assembly determines the consumption per stitch of the looper thread during the formation of the chainstitches. A processor identifies times when the monitored consumption is indicative of looper thread consumption per stitch below a predetermined threshold value. Since the consumption per stitch for looper thread is nominally a predetermined multiple of the stitch length, those identified times correspond to times when improper stitches have occurred.

摘要： An adaptive semi-automatic sewing system (10) comprises a sewing machine (12), a drive unit (42) including a variable speed direct drive motor and encoder for counting stitches sewn and for sensing the rotation of the motor, at least one material edge sensor (40) mounted ahead of the needle (22) of the sewing machine, and a microprocessor controller (51) coupled to the sewing machine controls. Accurate control of seam lengths and end points is achieved by initiating countdown of a variable number of final stitches responsive to detection of the material edge by the sensors (40). The amount of stitch completion at the time of detection of the material edge is monitored and a stitch length variance mechanism (17) is actuated at a selected angle of motor rotation taking into account the time delay of the stitch length variance mechanism and the feed characteristics of sewing machine (12) to precisely control the length of the last stitch sewn to improve the accuracy of the seam end point.

摘要： A control device for a sewing machine, in which the numbers of stitches in forward and backward feed of an article to be sewed are preset, comprises: a reverse-stitching electromagnetic operating unit for reversing the direction of feed of the article; a control unit for applying instruction signals to the electromagnetic operation unit to control the latter; and delay means for controlling the operation delay time between the turning "on" or "off" of the electrical instruction signal which is applied to the electromagnetic operating unit by the control means and the turning "on" or "off" of the electromagnetic operating unit. The time instant that the instruction signal is turned "on" or "off" by the control means is caused to occur a period of time, corresponding to the operation delay time, earlier than a predetermined time instant, so that the number of stitches preset is equal to the number of stitches actually formed.

摘要： A sewing machine is with a device for producing corner seams comprising a sensor which is located ahead of the needle and which releases the operation of stopping the needle at a predetermined corner point as soon as an edge of the work passes by. To exactly control the sticking in of the needle at a predetermined corner location, a pulse generator for delivering counting pulses and coupled to the main shaft of the sewing machine, is connected through a switching element to a setting counter, and is effective only during the advance phases of the feed dog motion. In addition, the sensor is connected to the switching element to switch it on as soon as the oblique edge of the work passes by, and the setting counter is connected to a device for instantly stopping the advancing effect of the feed dog, and to a device for stopping the sewing machine in the lowermost position of the needle, to release the operation of these devices as soon as a presettable number of pulses is reached. To instantly stop the advancing effect of the feed dog, the feed dog is connected to its lifting drive through a toggle lever which can be swung out by means of an actuating member controlled by the setting counter.

摘要： An adjunct control system for electronically controllable sewing machines which increases the flexibility of the sewing system by providing the functions of mechanically programmable stitch counting for each of a predetermined number of stitching sequences, programmable needle positioning, reverse stitching, thread trimming and wiping, and manually selected program interruption for selected conditions. A micro-processor auxiliary control system is utilized which is interfaced with a standard commercially available sewing machine control system in such manner that the sewing machine may be used in either its standard mode of operation without the micro-processor control, or may be used under micro-processor control. The micro-processor includes a central processing unit, a program memory, read/write storage, a control decoder and input/output devices for accessing the CPU and for interchanging control signals between the micro-processor and the standard sewing machine control system.

摘要： A stitch counter is disclosed for use on a sewing machine to count a predetermined number of stitches before stopping the machine and actuating the thread cutting mechanism. The counter is used in conjunction with existing control circuitry which includes a light beam generator and receiver located in front of the needle. The cloth being sewn interrupts the light beam, which allows the operator to select any sewing speed. The completion of the light beam after the end of the cloth passes, shifts the machine to a pre-set sewing speed and activates the stitch counter. The counter counts a number of pulses from a pulse generator on the machine, which are indicative of the number of stitches, before stopping the machine and actuating the thread cutter.
