| 13 | METHOD AND APPARATUS FOR AUTOMATIC ADJUSTMENT OF THREAD TENSION | EP99920372.2 | 1999-05-06 | EP1109961A1 | 2001-06-27 | MELTON, Randall; CHILDS, William, R.; TURNER, Vernon, Stephen |
| A computerized stitching apparatus that automatically controls thread tension is disclosed. In one embodiment, at least two factors are used to determine the desired thread consumption for the next stitch. A thread length encoder (23) is used to determine the amount of thread actually consumed for a particular stitch. The operator must enter a desired thread length ratio or an equivalent factor related to desired thread length used for a particular stitch into the operator input device (24). Another factor such as speed, stitch length, fabric thickness, or stitch angle change is used with at least the operator's input to determine the desired thread consumption. The tension of the thread is adjusted by a stitch control system (25) which will affect the actual thread consumed for the particular stitch. | ||||||

An apparatus for feeding thread for a sewing machine comprising a thread feeding system for guiding the thread (14) from a spool (13) to a take-up lever (2) of the sewing machine (A). The thread feeding device is comprised of a pressure roller (10) and a feed roller (8) driven by a motor, an encoding device (17) installed on the main drive shaft of the sewing machine, an encoder (8a) for measuring the length of the thread fed, and a thread holding device (11), whereby when the encoding device (17) gives the signal to the thread holding device to release the thread, the thread feeding device feeds the thread for completing one full stitch, and the encoder (8a) actuates the thread holding device (11) to hold the thread during the stitching. A second embodiment of the apparatus disclosures another thread holding device (7) which is installed between the take-up lever and the thread feeding device whereby the thread holding device grips the thread before the take-up lever starts tightening the stitch. |

| A method and a device for cutting at least an upper thread of a sewing machine provided with a fabric clamping member (20), wherein a length of the thread consumed for a cut can be set within a predetermined interval. The method for cutting at least the upper thread (4) of a sewing machine (1) includes the steps: feeding a predetermined length x of said upper thread (4) utilizing a thread feeder (15), pulling out the upper thread (4) said predetermined length utilizing a displacement of said fabric clamping member (20) from a current position to a second position executing by means of a sewing machine processor (C) program sequences stored in a memory (M) for controlling a thread cutter (10) to perform a cut of at least said upper thread (4). | ||||||

| A thread supplying device includes a rotator feeding a thread downstream of a thread supply path, the rotator winding a periphery thereof the thread several times and locating in the path extending from a thread supply part to a needle and loopers, a stepping motor continuously drivingly rotating in one way the rotator in synchronism with the main shaft of a sewing machine, thread feed setting means setting a unit thread feeding amount necessary for formation of seams per stitch, and control means automatically controlling the rotation of the motor to feed the unit thread feeding amount set by the setting means for each formation of seams per stitch. This device can stably supply a predetermined amount of the unit thread, and achieve stabilization of stitch performance, irrespective of the type of the thread, and whether the feed of a fabric increases or decreases by a rapid change in the rotational speed of the sewing machine. | ||||||

| A stitching apparatus with thread tension control is provided. Tension in a thread is monitored during stitching apparatus operations, and remedial action is taken in response to the detection of an anomaly in the thread tension profile. The remedial action can include altering a feed rate of the thread in order to adjust the thread tension, and/or repeating a previous operation. Anomaly detection can be performed with respect to stitching or sewing operations, and also with respect to trim operations performed in connection with moving between elements and/or thread color changes. | ||||||
