Abstract
The technical field of the present invention relates to an apparatus for automatically threading a warp through the eye of a heddle. In a conventional automatic warp threading apparatus, a drawing-in needle equipped with a hook is delivered out through the eye and is pulled back after hooking the warp so as to thread the warp through the eye. For this reason, the eye is likely to be damaged and a defect is likely to occur during weaving. The automatic warp threading apparatus of the present invention warp threading apparatus of the present invention clamps the warp (Y) with finger members (18, 18') disposed on a thread feeder (5) and a jet nozzle (20) fitted to the finger members (18, 18') ejects a gas so as to thread the clamped warp (Y) through the eye. Accordingly, the eye is not damaged and weaving can be made advantageously.
