Abstract
Various examples are provided for non-stop tying-in process for weaving of textiles. In one example, a method for non-stop tying-in of loom warps during operation of a loom includes providing free ends of a replacement warp sheet and a warp sheet tail to the tying-in machine during the operation of the loom, where the warp sheet tail is provided through a warp accumulator; accumulating the warp sheet tail in the warp accumulator during tying-in of the free ends; supplying at least a portion of the warp sheet tail accumulated by the warp accumulator to the loom after being released from a warp beam; removing the tied-in warp sheet tail and replacement warp sheet from the warp accumulator; and supplying the replacement warp sheet to the loom during its operation.
Claims20
A method for non-stop tying-in of loom warps during operation of a loom, comprising:
- providing a free end of a replacement warp sheet to a tying-in machine, the replacement warp sheet wound on a first warp beam;
- providing a free end of a warp sheet tail of an existing warp sheet to the tying-in machine during the operation of the loom, wherein the free end of the warp sheet tail is unwound from a second warp beam in the loom and is provided from the second warp beam to the tying-in machine through a warp accumulator separate from the loom, and wherein the existing warp sheet is simultaneously unwound from the second warp beam and supplied to the loom during the operation while the free end of the warp sheet tail is unwound and provided to the tying-in machine;
- accumulating the warp sheet tail in the warp accumulator as it is unwound from the second warp beam during tying-in of the free ends of the replacement warp sheet and the warp sheet tail by the tying-in machine;
- supplying at least a portion of the warp sheet tail that was accumulated by the warp accumulator to the loom after the existing warp sheet and warp sheet tail are released from the second warp beam;
- removing the tied-in warp sheet tail from the warp accumulator;
- and
- supplying the replacement warp sheet to the loom without stopping the operation of the loom.
A system for non-stop tying-in of loom warps during operation of a loom, comprising:
- a warp accumulator configured to accumulate warp sheet material of a warp sheet tail of an existing warp sheet being supplied to the loom from an installed warp beam;
- a replacement warp beam mounted on a portable support system, the replacement warp beam comprising a replacement warp sheet;
- and
- a tying-in machine configured to tie-in free ends of the replacement warp sheet and the warp sheet tail during accumulation of the warp sheet material by the warp accumulator.
