A sewing machine for sewing a stitch into an article is provided. The sewing machine includes a support structure, a first head and a second head. The first head is coupled to the support structure and includes a coupler contained within a second actuator assembly and 360° rotatable relative to the support structure and a first stitching element rotatable with the coupler and translatable via a first actuator assembly relative to the coupler. The second head is coupled to the support structure and includes a coupler contained within the second actuator assembly and 360° degree rotatable relative to the support structure and a second stitching element rotatable with the coupler via the first actuator assembly.

In a sewing machine, a switching mechanism is coupled to a slide arm of a transmission mechanism included in an upper feed mechanism. When the switching mechanism is operated, the slide arm is switched between a transmission state in which the driving force of a driving cam is transmitted to a feed link mechanism and a non-transmission state in which the driving force of the driving cam is not transmitted to the link mechanism 61. This allows the switching mechanism to switch the slide arm 60A to the non-transmission state. This allows the operation of the feed link mechanism to be suspended, and allows the upper-lower movement of an upper feed dog to be suspended. Accordingly, this contributes to a reduction in vibration and noise in the sewing machine.

A sewing machine system includes an optical encoder which senses relative movement between the sewing machine and fabric and varies the stitching speed of the sewing machine to create stitches according to a user selected stitch length.

A sewing machine includes a movement mechanism, a swinging mechanism, a presser device, a guide portion, a processor, and a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data used for sewing a couching pattern in which a plurality of motifs are continuously arranged. The motif is configured in a predetermined shape by a plurality of stitches including a main stitch and a sub-stitch. The processes include correcting at least one selected from the group of a start point position and an end point position of the main stitch of one of the motifs, such that the length of the main stitch of the one motif is longer in a second case than in a first case, and driving the movement mechanism and the swinging mechanism in accordance with the corrected pattern data.

The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data indicating positions of a plurality of needle drop points to sew a pattern, acquiring a position of a sewing start point of the pattern, performing first correction, performing second correction that uses the acquired position of the sewing start point as a base point, and corrects the pattern data, by changing, by an acquired change amount, the positions of the plurality of needle drop points represented by the pattern data corrected by the first correction, and controlling the sewing portion and the movement portion and sewing the pattern on the sewing object, in accordance with the pattern data corrected by the second correction.
