The invention relates to a circular loom for weaving a weaving core with at least one shuttle, which has a weft thread spool and is movable along a circular orbit path around the weaving core. At least one guide device, designed to guide at least one warp thread provided from a warp thread spool on a warp spool device, is movably arranged or designed outside a track plane enclosed by the outer circumference of the circular orbit path, the guided warp thread, crossing the track plane, passing through a recess in the circular orbit path.

The invention relates to a circular loom for weaving a weaving core along a weaving axis with at least one shuttle, which comprises a weft thread spool and is movable along a circular orbit path around the weaving core. The orbit path is formed of first track segments arranged one after the other along its circumference and at least one movably arranged or designed guide device is provided, which guides at least one warp thread provided from a warp thread spool on a warp spool device and on which at least a first track segment of the orbit path and at least a second track segment alternatively assignable to the orbit path are arranged and guided, where in the guided absence of the first and second track segment from the orbit path the guided warp thread, crossing the track plane, passes through the orbit path.

An apparatus for fabrication of a woven tubular nanotextile used in vascular graft applications. The woven nanotextile conduit is 0.1 to 50 mm in diameter and includes a multitude of hierarchically arranged nanofibers. They are made from low strength bundled nanoyarns containing thousands of nanofibers with improved mechanical strength. The weaving apparatus interweaves the warp and weft yarns in longitudinal and transverse directions, resulting in a flexible and strong woven product. The physical and biological properties of the woven nanotextile were significantly enhanced when compared to non-woven nanofibrous form and conventional medical textiles. The nanotextile displayed superhydrophilic behavior in an otherwise hydrophobic material and when implanted as a vascular graft was robust, suturable, kink-proof and non-thrombogenic, with complete endothelialization of the graft luminal area.

The invention is a warp breakage/end sensing system and a device to detect end of a miming yarn on a CWM used to make endless tubular fabric. The device of the invention incorporates a mechanism which causes a notification in the form of a signal (indicating yarn breakage or yarn end) to be sent to the loom operator in the situation where a yarn breakage is detected. The device employs a drop wire (6) which loses its elevation and falls (under its self-weight) from its normal operative position. The drop causes a first element (7) to rotate and come in contact (physical or non-physical) with a second element (8), thereby completing an electric circuit and sending a yarn breakage signal to the operator. Upon restoration of the yarn, the first element restores to its normal working position. In the case of a non-physical contact, the first sensing element enters the triggering region of the second sensing element thus causing a signal to be sent.

Described herein are techniques for creating a three-dimensional woven textile products. A method includes rotating strands of warp yarns, where each strand of warp yarn is in a direction away from a surface, in a circular motion while moving a strand of weft yarn forwards and backwards in a direction parallel to the surface so as to cause the strand of weft yarn to alternately weave in and out of the strands of warp yarn. The method includes moving the strand of weft yarn in a direction away from the surface so as to cause the strand of weft yarn to alternately weave in and out of the strands of warp yarn at a different height to create a three-dimensional woven textile product. The method includes supplying at least one of the strand of warp yarn or the strand of weft yarn with a yarn generator.
