A buttonhole sewing guiding device of a sewing machine includes a buttonhole presser foot unit disposed on a presser foot holder of the sewing machine, and a sensing unit disposed on the buttonhole presser foot unit. A presser frame of the foot unit is movable relative to a sliding member between first and second sewing positions set in accordance with an operating distance that corresponds to a size of a button to allow first and second triggering members to initiate a sensing module for controlling operation of a sewing needle.

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 sewing machine that sews an embroidery pattern on a sewing object includes an embroidery frame horizontally moving along a direction which a frame surface extends, a needle bar supporting a needle for inserting a thread, and reciprocally moving toward an internal space of the embroidery frame, a memory unit storing image data of the embroidery frame, and embroidery data of the embroidery pattern, and a display unit displaying an image of the embroidery frame, an image of the embroidery pattern within the image of the embroidery frame, and a feature point with a positional relation between the embroidery pattern, and the embroidery frame when actually sewn in accordance with the embroidery data.

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.

Systems and methods for producing printed goods from textile material to address shortcoming of existing approaches for article production. According to the systems and methods described herein, the harvested and woven cotton may be shipped directly to garment decorators who may perform all remaining steps to provide customers with finished goods. As such, the systems and methods herein may eliminate the steps of the blank goods trade and current manufacturing processes.

The present invention relates to a method of operating a quilting or sewing machine. In the method, an operator may switch the modes in which the sewing machine is operating. The modes may be switched when the sewing machine is in operation or when the machine is stopped. The modes to which the sewing machine may be switched to and from may be pre-set modes as defined by an operator. The modes that may be switched to and from may include settings for stitch mode and stitch speed. The buttons may be physical buttons associated with the sewing machine's handles, or they may be digital buttons associated with a tablet device.
