Weaving equipment may include warp strand positioning equipment that positions warp strands and weft strand positioning equipment that inserts weft strands among the warp strands to form fabric. The fabric may include insulating strands and conductive strands. The conductive strands may be coupled to electrical components. The warp strand positioning equipment may position the warp strands to form a shed. Component insertion equipment may be used to insert electrical components into the shed. The weaving equipment may have a reed. The reed may be used to help position an electrical component in the fabric. The weaving equipment may have take-down equipment and individually controllable warp fiber positioning and tensioning devices.

A machine for weaving or winding a fiber preform on a mandrel having an axis of rotation that is substantially horizontal and that serves to receive the preform, the machine having a plurality of cameras pointing towards the underside of the fiber preform in order to scan the hidden face of the fiber preform and acquire images of the hidden face; an image analysis module for processing these images of the hidden face of the fiber preform in a plurality of adjacent scan windows, and for extracting weaving patterns therefrom and comparing them with reference weaving patterns previously stored in the module; a motor for driving the mandrel in rotation about its axis of rotation; and a control unit for stopping rotation of the mandrel if the result of the comparison reveals a difference of appearance between the two weaving patterns.

A weft withdrawing device of an air jet loom includes a blow nozzle blowing a weft that is ejected from a weft insertion main nozzle and determined to be a weft insertion failure to guide the weft to a weft withdrawing passage, a weft introducing duct that is integrally swingable with a sley forward and backward, a weft withdrawing mechanism withdrawing the weft guided to the weft introducing duct, and a weft sensor optically detecting the weft. The weft withdrawing device of the air jet loom includes a weft guide member. The weft guide member includes a cloth fell side top portion and a let-off side top portion. The cloth fell side top portion is located above the weft withdrawing passage.
