Abstract
A method of weaving a spiral-shaped textile includes inserting in the vicinity of the fell of the textile a finger adjacent to a first intermediate warp fiber between a first edge and a second edge; forming a loop around the finger with the weft fiber; wrapping weft fiber around the first intermediate warp fiber between the first edge and the second edge of the textile to secure the weft fiber in a radial direction between the first edge and the second edge of the textile; extending the weft fiber to the first edge of the textile; securing the weft fiber using a knitting system on the first edge of the textile; and removing the finger from the textile.
Claims19
A method of weaving a spiral-shaped textile with a first edge and a second edge in a radial direction and a fell, the method comprising:
- inserting in the vicinity of the fell of the textile a finger adjacent to a first intermediate warp fiber between the first edge and the second edge;
- forming a loop around the finger with the weft fiber;
- wrapping weft fiber around the first intermediate warp fiber between the first edge and the second edge of the textile to secure the weft fiber in a radial direction between the first edge and the second edge of the textile;
- extending the weft fiber to the first edge of the textile;
- securing the weft fiber using a knitting system on the first edge of the textile;
- and
- removing the finger from the textile.
A method of weaving a helical textile comprising:
- a) inserting in a first shed a weft yarn with a weft needle from the second side to the first side of the textile in the radial direction;
- b) securing the weft yarn to the first side of the textile;
- c) retracting the weft needle from the first side to the second side of the textile;
- d) beating a fell of the textile with a reed;
- e) creating a second shed;
- f) inserting the weft needle into the second shed from the second side to the first side of the textile;
- g) inserting a finger in the vicinity of the fell and adjacent to an intermediate warp yarn located between the first side and the second side;
- h) looping the weft yarn around the finger to secure the weft yarn on the intermediate warp yarn;
- i) securing the weft yarn to the first side of the textile;
- j) removing the finger from the textile;
- k) retracting the weft needle from the textile;
- l) beating the fell of the textile with a reed;
- m) creating a third shed;
- n) inserting the weft needle into the third shed;
- and
- o) securing the weft yarn to the first side of the textile.
A spiral-shaped woven textile with a first edge and a first edge, the textile comprising:
- a single weft yarn extending varying distances from the first edge to the second edge so that some loops are secured to the second edge and some loops are secured to one or more intermediate warp yarns at locations between the first edge and the second edge so that no holes are present in the woven textile.
