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.

A sewing machine includes a feed amount setting part and a feed amount adjustment part. In the feed amount setting part, a forward feed amount for one stitch of forward stitching is set. In the feed amount adjustment part, the forward feed amount which is set by the feed amount setting part is compared with the maximum backward feed amount for one stitch of reverse stitching which is determined by a feed mechanism. Then, in the feed amount adjustment part, when the forward feed amount is larger than the maximum backward feed amount, the total amount of backward feed amounts for plural stitches of backward stitching is adjusted so as to coincide with the total amount of the forward feed amounts for one stitch or more of forward stitching.

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.

A sewing control device includes in a sewing machine having upper feed function a control device which controls feed of an object to be sewn. A lower feed amount setting motor sets a feed amount of a lower feed dog and an upper feed amount change motor changes a feed amount of an upper feed dog. A feed execution range, in which the feed of the object to be sewn is executed by an appropriate feed amount while the object to be sewn is sandwiched between the lower feed dog and the upper feed dog, and a feed non-execution range, in which the feed of the object to be sewn is not executed in a state in which the feed dogs do not act on the object to be sewn, are present. The feed amount of the upper feed dog can be changed only in the feed non-execution range during sewing.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate augmented-reality features such as projecting assistive visual elements or virtual UI elements into an operational area. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.
