A method of manipulating warp yarns fed to a loom for producing a weave design comprising:

• (a) disposing flexible elements over opposed upper and lower arcuate surfaces which in turn are disposed along parallel axes in said loom for forming a plurality of scrolls supported by said arcuate surfaces, said scrolls having the flexible elements in parallel, upright, tranversely extending adjacent planes tangent to said arcuate surfaces;
• (b) supporting eyes by said flexible elements in the planes of said scrolls for movement upwardly and downwardly in the parallel, transverse planes of said flexible elements;
• (c) rocking said arcuate surfaces about their respective axes for applying tension to said flexible members while imparting reciprocating motion to the flexible elements along the plane of each scroll so that each of said eyes are pulled upwardly or pulled downwardly by said flexible elements;
• and
• (d) progressively feeding warp yarns respectively through said eyes for weaving action of the loom while moving the eyes of one plane in one direction and moving the eyes of an adjacent plane in the other direction for separating the warp for forming a shed.
