A method of fabricating pattern composite fabric pieces by an automatic pattern fabric article piece processing machine is described. A composite fabric sheet is fed in the processing machine onto a conveyor having a permeable belt under which is provided a vacuum chamber to retain the fabric sheet stationary while a laser cutter effects a programmed job function. The machine forms seam allowance flaps for the composite fabric pattern piece. A stitching or ultrasonic bonding machine also forms seams. In a further stage, printed matter may be applied to the allowance flaps. Glue may also be applied to the flaps and labels to some of the pattern fabric pieces. By interconnecting the seam allowance flaps of different fabric pieces, in a specific order, a fabric material article is produced.

A hook and bobbin locator apparatus and method consisting of a mounting plate and more than one hook and bobbin combination. Each of the more than one hook and bobbin combinations is connected with a stepper motor and each of the more than one hook and bobbin combinations are removably connected with the mounting plate. A stepper motor is also connected with the mounting plate and a controller is connected with the mounting plate stepper motor and the hook and bobbin combination stepper motors such that movement of the mounting plate and the hook and bobbin combinations are controlled by the controller.

A method for identifying reference points in a hand drawing track with a number (n) of dots includes marking a first one of the dots as a reference point; for each of a (k.sup.th) one of the dots, determining an included angle; marking the (k.sup.th) one of the dots as a reference point when the included angle associated therewith is larger than a predetermined angle; calculating an accumulated distance between the (k.sup.th) one of the dots and a last one of the reference point (s) thus marked when the included angle is not larger than the predetermined angle; and marking the (k.sup.th) one of the dots as a reference point when it is determined that the accumulated distance thus calculated is larger than the predetermined distance, 2k(n1).

The present invention provides a sewing machine that can actuary detect a physical amount of a movement of a fabric without depending on an estimated value. Thus, thread tension can be precisely adjusted. A sewing machine 1 includes a spherical body 22a exposed partly from a needle plate 2. The spherical body 22a is rotated following a feed of a fabric 100. The rotation of the spherical body 22a is detected by rotary encoders 22c, 22d. A physical amount of the movement of the fabric 100 is calculated based on a detection result of the rotary encoders 22c, 22d. The physical amount of the movement of the fabric 100 is, for example, a moving amount and a moving speed.

The present invention relates to a quilting machine, or stitcher, further including a centrally located swiveling tablet mount for securing a tablet that is used in the quilting process. The mount is positioned such that a user may access the mount from either side of, or the rear or front of the stitcher. The mount is one capable of swiveling so that the user does not have to move the tablet between front and rear mounts of the stitcher or buy separate tablets for a front and rear mount.

A sewing machine includes at least: a movement detection unit for detecting a movement amount of a material to be sewn; a drive motor for operating a needle; a control unit for operating the drive motor; and a storage unit. The storage unit stores a sewing speed and a sewing pitch. The control unit is configured to implement a first control mode and a second control mode. In the first control mode, the control unit operates the drive motor at the stored sewing speed when the detected value by the movement detection unit exceeds a predetermined first threshold. In the second control mode, the control unit operates the drive motor such that the sewing is carried out at the stored sewing pitch on the basis of the detected value when the detected value exceeds a predetermined second threshold. These first control mode and second control mode are switchable.

The industrial sewing machine includes: a web server, based on a request from a web browser installed on an information terminal, providing the web browser with an operation screen simulating an operation panel, and receiving operation data generated by operating the operation screen; and a sewing machine control part, controlling a sewing machine operating part based on the operation data.
