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.
Claims17
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.
