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. The two cylinders can be rotated together in one direction or in an opposite direction for causing the slots to move the guides and hence the dents apart or together to obtain changes in the width of the fabric along the warp direction. 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.
