Abstract
A shed-forming apparatus for a weaving machine includes warp thread guiding healds reciprocated vertically between an upper shed position and a lower shed position; a lowering frame; and return springs attached to each heald and to the lowering frame to reset the healds into the lower shed position. The lowering frame supports a channel through which an air stream is forced. The return springs are coupled to the channel for exposing the return springs to a pressure of an air flow to prevent dust deposition and lint formation on the return springs.
