    摘要: A low-cost sewing machine capable of achieving a desired balance between needle thread consumption and bobbin thread consumption is described. A memory section stores needle thread requirement data having precorrected needle thread requirement and postcorrected needle thread requirement. In a torque control zone, rotating force is imparted to a turning arm so as to impart a tension on the needle thread according to a torque value, while closing an upstream grip section main body and while opening a downstream grip section main body. In a first position control zone, the needle thread is drawn according to the postcorrected needle thread requirement, while opening the upstream grip section main body and while closing the downstream grip section. In a second position control zone, the turning arm is returned to an initial position, while closing the upstream grip section main body and while opening the downstream grip section main body.

    摘要: Presented are a method, apparatus, and computer-readable medium for stitching. The method includes examining, by an examiner, an embroidery design, wherein the examiner is operably coupled to a controller and a sewing head, and wherein the controller comprises a memory having a capacity, and wherein the controller is operable to cause the sewing head to stitch a work piece. The method further includes determining, by the examiner, a needle drop location of each stitch of the embroidery design, and dividing, by the examiner, the examined embroidery design into a plurality of separate sections. The method still further includes transmitting the plurality of separate sections at a plurality of different times to the controller such that the controller the plurality of separate sections do not exceed the capacity of the memory at any one of the plurality of different times.

    摘要: A sewing machine includes a sewing portion sewing an embroidery pattern on a cloth, a first storage portion storing the stitch data and pattern data, a display portion, a processor, and a memory storing computer-readable instructions. The computer-readable instructions, executed by the processor, includes first acquiring the stitch data and the pattern data, and first displaying, based on the pattern data, the pattern image on the display portion. The computer-readable instructions also includes, first generating a plurality of partial images representing a number of stitches corresponding to a first predetermined number, based on the stitch data, after the first displaying of the pattern image on the display portion, and second displaying, each time each of the plurality of partial images is generated by the first generating, the generated partial image on a portion of the pattern image displayed by the first displaying that corresponds to the generated partial image.
