摘要： A weft thread cutting device for shuttleless looms is placed between a fabric edge, a comb and a warp mouth, on one side, and a weft thread selector, on the other side. Weft threads, coming from a plurality of eyelets, join at a vertex located at the fabric edge and at the beating line of the comb. The weft thread cutting device has a rotating disk with a cutting edge, configured to cut the weft threads by a motor which keeps the rotating disk in rotation, and a step control motor, which, through a rotating shaft provided with an eccentric, controls motion of a hinged lever swinging with respect to a longitudinal axis of the step control motor. The hinged lever is shaped, at one end, in the form of two arms, respectively resting on the surfaces of two elastic plates, and is connected, at the other end, to the eccentric.

摘要： A linking machine (104) comprising a fixed unit comprising a support frame (108), a mobile unit (200) comprising a device for advancing or transporting (116) the fabric along a longitudinal direction (Y-Y), a device for positioning (120) a needle (110) along a transverse direction (X-X), perpendicular to said longitudinal direction (Y-Y) and coplanar with the fabric, an actuator device (124) of said needle (110) in a vertical direction (Z-Z), perpendicular to said longitudinal (Y-Y) and transverse (X-X) directions, for performing the linking. Advantageously, the linking machine (104) comprises a feed guide (20) for two fabrics to be joined, such as a neck (1,10), provided with a separating cotton (3) and a knitted fabric (6), positioned upstream of said needle (110) in the longitudinal direction (Y-Y). The feed guide (20) comprising a first stop (21) suitable to constitute an abutment and a positioning for said separating cotton (3) of the neck (1,10), said first stop (21) being adjustable in position along said transversal direction (X-X) so as to be able to adjust a distance (a) of the seam line (13) from the inner edge of the neck (5).

摘要： A defect identification device for identifying defects in fabrics comprising a support frame fitted with a crossbar supporting at least one video camera for capturing images of a fabric while it is being woven, movement means for moving the at least one video camera, a processing and control unit programmed to control the movement means to move the video camera automatically in real time along a transverse weft direction (X-X), acquiring in advance the geometry of the fabric to be made and setting at least one theoretical dimensional parameter of comparison and a tolerance limit value for said theoretical dimensional parameter, capturing images of the fabric being formed in real time, processing said images so as to acquire said actual dimensional parameter of the fabric being formed and compare it to the theoretical dimensional parameter, detecting the presence of a weaving error.
