ABSTRACT:
In the circular reed of the circular loom, a plurality of weaving shuttles circulate. Each weaving shuttle has rollers arranged in pairs at its top edge and its bottom edge. The rollers operate together with the corresponding gliding surfaces on the upper shuttle race or lower shuttle race of the circular reed, and each shuttle is supported to circulate on shuttle guide rods by the centrifugal force conveyed by the support elements. The shuttle guide rods of the circular reed define between them a slit in the region of the upper and the lower shuttle races, which slit receives upon opening of the travelling shed one of the warp threads of the upper shed or the lower shed, and form there an upper and a lower rollway, taking up the centrifugal force of the circulating weaving shuttle for the respective pairs of support rollers on the shuttle. The slit widens outside the rollways towards the reed-horizontal median plane to a warp-yarn crossing space. These measures permit a rapid increase of the rotational speed of the weaving shuttle and the utilization of larger warp yarn packages.
