Patent ID: 8596303

Claim:
In a handloom for constructing a woven fabric and that includes a warp beam, a harness for supporting and controlling warp threads that extend in a warp thread direction, a reed for spacing the warp threads disposed adjacent to the harness for supporting the warp threads, and a shuttle for passing weft threads that extend in a weft thread direction, said shuttle carrying the weft threads across the warp threads that are either raised or lowered by the harness creating a shed the improvement comprising a supplementary beater adapted for manual insertion into the shed and for the purpose of providing an undulating weft pattern in the woven fabric; wherein the supplementary beater is elongated, having opposed elongated one and other side edges; wherein the one of the side edges has a continuous undulating surface edge facing toward a newly introduced weft thread; wherein the supplementary beater is constructed and arranged so that the undulating surface edge, when the supplementary beater is so inserted into the shed, extends generally in a direction that is substantially orthogonal to the warp thread direction; wherein the undulating surface edge of the supplementary beater has multiple alternating continuous edge peaks and valleys; wherein the undulating surface edge has undulations of different period therealong including at least first undulations of a period greater than the undulations of a second period.
