Apparatus for beating-up weft thread in travelling wave shedding looms

摘要

An apparatus for beating-up weft thread to be used in traveling wave shedding looms comprises a stationary reed for dividing warp threads and a rotary shaft having plates secured thereto and forming combs arranged helically along the shaft. The plates of at least one comb are made and arranged relative to plates of other combs in such a manner that planes of revolution of at least a portion of each plate of the comb, during rotation of the shaft, are displaced along the shaft away from the plane of revolution of plates of other combs. This arrangement of plates enables the maintenance of warp threads in the position set-up by the dividing reed, thereby improving quality of cloth being manufactured.
