Abstract: For producing woven fabrics with additional pattern effects, one or more effect threads are supplied substantially in the warp direction and are moved over neighboring warp threads in the weft direction, above a weft thread that is to be inserted, in various motion cycles of a weaving machine.

Abstract: The reed employs two spaced apart cylinders with slots in their outer surfaces. The slots extend around the axis of each cylinder a given distance. The slots of each cylinder flare out from each other from one edge to an opposite edge. Dents are supported for movement between the two cylinders and have guides located in the slots of each cylinder.

This change in width will cause the warp density to vary along the length of the fabric while maintaining continuous warp yarn. This feature also allows warp strands of different cross-section to be woven.
