A DEVICE FOR CONTROLLING WARP THREADS FOR THE PRODUCTION OF LENO FABRICS ON A TEXTILE MACHINE

摘要

A device for controlling warp threads for the production of leno fabrics on a textile machine comprising a reed (1) equipped with gliders separated from each other by slots intended to guide pairs of warp threads, one of which belongs to a system of stationary warp threads (19), and the other, to a system of rotating warp threads (18), with a reversibly moveable system of needles (3) fitted with eyes (4) for guiding the system of stationary warp threads (19) arranged in front of the reed (1) and coupled with a mechanism adapted to impart to it said reversible movement, further comprising vertically adjustable heddle frames (10, 11, 14) situated in front of said system of needles (3), a first heddle frame having oblique slots for the passage of the rotating warp threads (18), the other one, a straight slot (13) passing through the whole width of the warp for the passage of the warp thread system (18). At least one guide member (20) of the stationary warp thread system (19) situated over the heddle frames (10, 11, 14) in parallel with them is coupled with the system of needles (3) fitted with eyes (4) and at least two compensation rollers (15) of the rotating warp thread system (18) are mounted on a third heddle frame (14).
