This vascular stent graft (1) is formed of a tubular knitted textile structure, integrating within the meshes of said knitted textile structure at least one helical continuous weft yarn (3) extending all along the major dimension of the stent graft.

Said at least one stent graft (3) is made of a shape memory alloy having previously been submitted to such an education, and in particular such a thermomechanical treatment that, at the human body temperature, said yarn gives the structure its tubular shape by superelasticity or shape memory effect.

The invention relates to a method and a device for producing an annular multiaxial laid fabric and to an annular object produced therewith. The object of the invention is therefore to create a method and a device for forming a multiaxial laid fabric for annular structures which has no twisting or displacement of the thread layers. Furthermore, it should no longer be necessary to close a butt join or overlap separately to form a closed ring of the multiaxial laid fabric. This object is achieved in that at least a lower thread layer (2a) and an upper thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, are laid around the entire circumference of two mutually spaced ring elements (3) with differing thread orientations, and the first and upper thread layers (2a, 2b) are then fixed to each other at points.

The invention relates to an apparatus for presenting threads for loop-forming tools, arranged in at least one row, of a textile machine having a thread guide apparatus having at least one rotary element (4, 5, 20, 21, 30, 31, 40, 41) having at least one thread guide (20a, 20b, 21a, 21b 30a, 30b, 40a, 40b), said thread guide apparatus being configured to lay a thread back and forth in two directions (HI, HR) in each case in front of a row of the tools in an entire stroke range (BG). The thread guide apparatus has at least two rotary elements (4, 5) arranged as a pair, wherein the rotary elements (4, 5, 20, 21, 30, 31, 40, 41) of a pair are arranged eccentrically with respect to one another and one above another in the axial direction, and wherein the rotary elements (4, 5) of a pair are drivable in opposite directions of rotation (R1, R2). Each rotary element (4, 5, 20, 21, 30, 31, 40, 41) has at least one thread guide (4a, 4b, 4c, 5a, 4b, 4c, 20a, 20b, 21a, 21b, 30a, 30b, 40a, 40b), configured as a driver element, for laying the thread in one of the directions (HI, HR).

A method for producing a textile sheet heating element includes forming a knitted material and, in one and the same work step, inserting heat conductors as warp threads. Contact conductors that touch the heat conductors are inserted spaced from one another as weft threads or weft thread groups. A warp knitting machine or Raschel machine is used to produce the sheet heating element. The production speed of the knitting or Raschel machine is varied as a function of stitch formation. The warp knitting machine or Raschel machine has a magazine weft insertion system with feeding chains to feed in weft threads and a weft carriage to insert weft threads. Both the feeding chain and the weft carriage are paused for preset periods as a function of stitch formation.

This invention provides a knitted wire carrier for use in constructing a (e.g.) automotive weather seal that incorporates a locking stitch formed from a relatively incompressible and expansion-resisting material that passes through at least one of the warp threads adjacent to the wire weft. In an embodiment, the locking stitch constructed from a steel (or another metal) wire that is solid or braided. In other embodiments, the locking stitch can be constructed from fiberglass, monofilament polymer or another similarly performing material. In an embodiment, the lockstitch wire is constructed from approximately 0.5-millimeter diameter steel and the wire carrier is constructed from approximately 0.5-0.91-millimeter diameter steel. The wire lockstitch can be woven through a center warp yarn that is surrounded by other knitted warp yarns along the overall weft of the wire carrier. The wire carrier is coated with an adhesive, e.g., latex to maintain the knit in place.
