A sewing device includes: a plurality of actuators; and a plurality of seating bodies that are provided in an attachable/detachable manner to the individual actuators to seat on certain regions of an object-to-be-sewn. The sewing device further includes a restraining jig. Due to the restraining jig collectively restraining the plurality of seating bodies provided to the actuators, the plurality of seating bodies can withdraw from the actuators.

The sewing system includes a device and a sewing machine including a movement mechanism to move an embroidery frame. The device identifies reference point coordinates representing a position of a reference point provided in a range prescribed by an inner frame of the embroidery frame and transmits the reference point coordinates to the sewing machine. The sewing machine notifies a notification position, using a notification portion, with respect to the range prescribed by the inner frame and acquires a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notification position and the reference point provided in the range prescribed by the inner frame. The sewing machine decides, on the basis of a relationship between the movement amount and the reference point coordinates, a deviation from a prescribed state of a positional relationship between the inner frame and the movement mechanism.

Provided is a sewing machine in which a stitching needle and a holding frame holding an article to be sewn are positioned relative to each other based on sewing pattern data defining a plurality of needle drop positions, and sewing is performed in accordance with a sewing pattern. The sewing machine includes: an imager for capturing an image of the holding frame; a position detector for detecting, from the image captured by the imager, the position of an indicator indicating a reference position marked in an object to be imaged; and a corrector which, based on a deviation of a detected position of the indicator detected by the position detector with respect to a regular position defined in advance for the indicator, corrects a plurality of needle drop positions defined in the sewing pattern data.

Various examples are provided related to attachment of bands about a garment opening. In one example, among others, a sleeve band can be attached to a garment by loading the sleeve band on a band guide, aligning an opening of a garment over the sleeve band, and attaching the band to the garment along the edge of the opening. Alignment of the edges of the opening and the sleeve band can be maintained by ply aligners during attachment. In another example, a garment holding system includes a garment holder that can receive a garment and a band positioning system includes a band guide that can receive a band. Edges of the opening of the garment and the band can be controlled and maintained with ply aligners of the band positioning system.

Various examples are provided related to transporting and sewing material in, e.g., automation of sewing robots. An automated sewing process feed control system is disclosed in which a material aligner is utilized. An omni-chain material aligner can include a circular roller chain in which the rollers allow for a controlling force to be applied to a material. An omni-belt material aligner can include a belt with attached perpendicular rollers which allow feed control and active motorized steering control. The material aligner can control the pressure applied onto the material to facilitate control of feeding the material.

A sewing assembly to make a seam along a determined path on a surface of a part. The sewing assembly includes a mask adapted to be fixed to the part and a sewing machine, the mask having a guide groove adapted to be superimposed on the path. The sewing machine includes a base and a head. The head has at least one needle, a part support foot and a guide, the guide including a front guide and a rear guide arranged to interact with the mask and spaced apart from each other along the guide groove. The at least one needle and the support foot are engaged in the groove between the front guide and the rear guide.

A sewing machine includes a sewing portion, a movement portion, a processor and a memory. 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.
