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.

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.

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.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate patch library systems that may enable the storage and retrieval of patch configuration information. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate 3-dimensional vision systems that may enable operations on non-flat objects and paths. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

Apparatus and methods are provided for automatic edge positioning and guiding of a moving web, such as a textile fabric or carpet, onto a conveyor system comprising manufacturing operations such as sewing, for example. More in particular an apparatus is provided including mechanics, optics and control for steering and positioning the side edges of the moving web in order to correct for misalignment, and hence sewing can occur appropriately.
