Abstract
Method and apparatus for producing a narrow fabric, such as for example curtain heading tapes and in which one weft is of relatively stiff form and a second weft has a high coefficient of friction relative to that of the stiff weft, and wherein the stiff weft is inserted only in curtain warp sheds and the second weft is inserted only in other warp sheds.
Claims23
The method of weaving a narrow fabric having a first weft of relatively stiff form, a second weft which has a high coefficient of friction relative to said first weft, and a multiplicity of warp yarns, including the steps of creating a shed, inserting a weft into said shed, beating-up the inserted weft, changing the shed and inserting a successive weft, beating-up the said successive weft, and repeating the steps to produce a woven fabric, the said weft insertion steps comprising inserting said first weft in certain warp sheds only and said second weft only in the other warp sheds, the said warp sheds being successively formed in the same plane thereby to enable said first and said second wefts to be contained in a common single weft plane in the fabric.
Apparatus for producing a narrow fabric including heald frames for shedding warp yarns, supply means for a stiff weft and a means for shedding said stiff weft, a reed, means for guiding same said stiff weft warpwise to a position forwardly of said reed, supply means and shedding means for a second weft means for shedding said second weft and guiding same warpwise to a position forwardly of said reed characterised in that there is provided a slip sickle weft inserter (as herinbefore defined) adapted to insert the said stiff weft and the second weft in predetermined sequence in different warp sheds formed by said warp shedding means.
Apparatus for producing a narrow fabric as claimed in claim 19 including at least one additional supply means and means for shedding at least one further weft and guiding same warpwise to a position forwardly of said reed, characterised in that there is provided an additional weft inserter for each further weft.
Apparatus for producing a narrow fabric including heald frames for shedding warp yarns, supply means for a stiff weft, means for shedding said stiff weft, a reed, means for guiding said stiff weft warpwise to a position forwardly of said reed, supply means for a second weft, means for shedding said second weft and guiding same warpwise to a position forwardly of said reed, characterised in that a shuttle is provided for carrying a catch thread adapted selectively to draw weft loops of said stiff weft and said second weft through successive warp sheds.
Apparatus for producing a narrow fabric including heald frames for shedding warp yarns, supply means for a stiff weft, means for shedding said stiff weft, a reed, means for guiding said stiff weft warpwise to a position forwardly of said reed, and a shuttle adapted to carry a yarn which selectively acts as a catch thread and as the second weft.
