A sewn product making apparatus such as a sewing robot can be used to produce a variety of products over a broad range of sizes, shapes or materials. Various examples are provided related to the automation of sewing robots, and the making of sewn products. In one example, among others, a system can generate a product making path using a product construction file, and instruct a sewing device and fabric mover(s) to automatically sew the product based upon the product making path. The product making path can be modified when a deviation is detected, and the sewing adjusted based upon the modified product making path. The product construction file can be generated using information from a computer aided design associated with the product.

A sewing mechanism is provided with: a post bed and sewing needles, wherein an article to be sewn is interposed between the post bed and the sewing needles. When the post bed comes closer to the article to be sewn than that in the previous sewing by at least a predetermined distance, in other words, when a separation distance between the article to be sewn and the post bed becomes less than that in the previous sewing by at least a predetermined distance, a thread pulling mechanism pulls threads hooked in needle holes of the sewing needles in a direction away from the post bed.

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.

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.

Sewing machine with a sewing machine housing (2) comprising a lower housing part (3), an upper housing part (4) with a sewing head (6) and a stand (5), which connects the lower housing part (3) to the upper housing part (4), wherein the upper housing part (4) comprises a stand-side arm housing section (7), a head-side arm housing section (8) and a joint (23), wherein the joint (23) is arranged in such a manner that the head-side arm housing section (8) can be swiveled between a preparation position for the picking up/delivering of a sewing material and a sewing position for sewing the sewing material.

Various examples are provided related to attachment of bands such as, e.g., collar or neck bands, sleeve bands, wrist bands, waist bands and ankle bands, etc. to a garment opening. In one example, among others, a band can be attached to a garment by loading the band between rollers in a joining position, positioning an opening of a garment extending between control surface mandrels over the band, and attaching the band to the garment along the edge of the opening.

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 pattern acquisition processing of acquiring data relating to an embroidery pattern, first position information acquisition processing of acquiring first position information indicating a position of the holder when the holder is in a first position, second position information acquisition processing of acquiring second position information indicating a position of the holder when the holder is in a second position different from the first position, generating processing of generating sewing data for sewing the embroidery pattern re-shaped on the basis of the first position information and the second position information, and sewing control processing of controlling the sewing portion and the movement portion in accordance with the generated sewing data.

Machine for sewing envelopes into pouches, in correspondence with an opening delimited by two free overlapping flaps, the machine includes a support base; a sewing head, mechanically mounted on the support base, configured to make a sewing line along a sewing direction; retaining means for retaining the free flaps of said envelope like a bag; first movement means for realizing a relative movement between said sewing head and the holding means along a first movement direction substantially parallel to the sewing line; second movement means for moving the sewing head and/or holding means at least along a second movement direction orthogonal with respect to the first movement direction; at least a first sensor configured to detect an extremal edge of the free edges; at least one electronic control unit for generating the relative motion between the support base and/or the holding means along the second movement direction.
