Apparatus for the production of short warps especially for cloth designs in multicolor weaving

Apparatus for the production of short warps, particularly for cloth designs in multicolor weaving, comprising means for successively winding up yarns of different colors upon a drum, means for selectively intermittently rotating said drum, said drum having a cylindrical portion and a conical start portion, means mounting lease rods for displaceable movement along the drum axis, a support, means for supplying a yarn sheet to the drum, means mounting said support for displaceable movement along the drum axis, heald frame means carried by said support for producing yarn sheds from the yarn, the improvement characterized by first and second lease rods operative respectively prior to and after a first yarn shed by said heald frame means to maintain a first yarn crossing therebetween formed by first and second yarn sheets, said heald frame means being further operative to divide said first and second yarn sheets into respective first and second pairs of yarn divisions, third and fourth lease rods operative after the division of the first and second yarn sheets and respectively positioned between the first and second pairs of yarn divisions, means for selectively displacing said first through fourth lease rods to maintain the first yarn crossing of the first and second yarn sheets and the first and second pairs of yarn divisions from the first and second yarn sheets;

• and control means for coordinating the operation of said first through fourth lease rods, said heald frame means and the intermittent rotation of said drum to produce said first and second yarn sheets, said first yarn crossing and the first and second pairs of yarn divisions.
