Abstract

A feeder for supplying a warp to a weaving machine is described. The feeder includes a drum non-rotatably supported by a drum shaft, a driving section connected to the drum shaft, a flyer wrapping warp around the drum, the flyer being supported by and rotatable with the drum shaft, a warp sensor pivotably supported in one of a plurality of slits formed in the drum, at least one supporting member eccentrically movable and slantable with respect to the drum shaft, and at least one carrier born by the at least one supporting member and guided by the plurality of slits respectively to be movable in both an axial direction and in a radial direction. The flyer transport the warp wound about the drum in the axial direction with the supporting member rotatably mounted on the drum shaft. A dial having a cam-like slant surface is attached to the drum shaft so as to enable a inclination angle adjustment of the slant surface. By the adjustment of the dial, the supporting member is inclined. This facilitates pitch adjustment of the feeder without the necessity of disassembling the unit. The sensor member can be operated with a very slight touch, giving a more sensitive sensor. Thus a clutch for preventing reverse rotation is provided between the driving section and the flyer, making it possible to prevent reverse rotation of the motor due to the tension of the warp, exerted when the flyer is stopped. This prevents the application of torsion upon the warp and the degrading thereof of the warp.
