摘要： A presser foot (1) for a sewing machine, having a shank (4) for fastening the presser foot (1) to a sewing machine, a needle opening (5) through which the sewing machine needle is able to be guided during sewing, and a presser foot sole (6) having an elongate depression (7) in the presser foot sole (6). The elongate depression (7) forms a guide wall which during sewing is configured to guide a filler material (8) to be sewn into the fabric (2) in the transport direction laterally beside the needle opening (5) and past the needle opening (5), and press said filler material against the fabric to be sewn, wherein the spatial extent of the elongate depression (7) is variably adjustable.

摘要： A method for calibrating one or more optical sensors on a sewing machine, including collecting data of one or more features of one or more predefined regions associated with the sewing machine, processing the data through one or more neural networks, wherein the one or more neural networks detect and recognize the one or more features of the one or more predetermined regions from the data, calculating one or more accuracy indicators of the one or more features from the data as compared to one or more trained features from the one or more neural networks, comparing the value of the one or more accuracy indicators to one or more indicator thresholds and adjusting one or more parameters of one or more optical sensors based on the comparison between the one or more accuracy indicators and the one or more indicator thresholds.

摘要： It is intended to improve texture of a decoration using a stitch line while improving workability in sewing for forming the stitch line at a skin material, to promote manufacturing efficiency as compared to formation of a stepped shape only by sewing, and to reduce the number of steps. A skin material is used for a conveyance seat, and is molded using a die. The skin material includes a linearly-extending stepped portion having a stepped shape transferred from the die, and a stitch line sewn along the stepped portion. The stepped portion serves as a guide upon formation of the stitch line.

摘要： A sewing system comprises a sewing machine, a camera that captures an image of a reference position for sewing, a robot arm that holds the sewing machine and the camera, and a controller. The controller controls operations of forming a first stitch position that results from stitching of the sewing machine, and forming a second stitch position that results from stitching of the sewing machine after rotating the sewing machine at a prescribed angle about a rotation axis that passes through a needle center position stored by the controller. The controller further performs calibration processing that calibrates the needle center position stored by the controller, based on each position of the first stitch position and the second stitch position within image capture ranges of capture images that are obtained by capturing images of the first stitch position and the second stitch position using the camera.

摘要： A sewing machine includes an arm portion, a thread spool mounting portion, a bobbin winder, a first guide portion, a second guide portion, and a partition wall member. The arm portion is provided with a drive shaft extending in a first direction. The thread spool mounting portion includes a thread spool pin to be inserted through a through hole of a thread spool. The bobbin winder is provided further to one end side of the arm portion than the thread spool mounting portion. The first guide portion is provided further to another end side of the arm portion than the thread spool mounting portion. The second guide portion is provided further to another end side in the first direction of the arm portion than the first guide portion. The partition wall member is disposed between the thread spool pin and the first guide portion in a second direction.

摘要： An object of the present invention is to provide an embroidery cloth presser which prevents a needle thread from being sandwiched between the embroidery cloth presser and a cloth to allow an embroidery frame to move smoothly and which also prevents inappropriate draw-in of the needle thread, that is, prevents a cross-over thread of the needle thread resulting from long-distance movement of the embroidery frame from remaining on an embroidery surface. An embroidery cloth presser is installed on a presser bar of a sewing machine to press a cloth to be embroidered and which includes a projection provided on a bottom surface of the cloth presser which contacts the cloth around a needle and forming, between the cloth presser and the cloth, a gap through which a needle thread passes.
