METHOD OF FORMING FABRIC WITH VARIABLE DENSITY OF FILLING THREAD Russian patent published in 2013 - IPC D03D49/00 

FIELD: textiles, paper.

SUBSTANCE: method of forming fabrics with variable density of filling thread arrangement, that lies in the fact that before filling thread beating fabric is moved to a distance greater than technology requires and then supplied toward the comb. At that in transition of density of fabric on weft the value of fabric supply towards the comb and the value of prior removal of fabric change. At the beginning of forming of a new portion with new density of filling thread during one cycle of fabric forming edge of fabric moves in the direction of mastitis (during transition to the thinned portion) or towards the remise (during transition to compacted portion) to a Δ=λb-λth where Δ is the displacement of fabric, λb is value of beating area in forming of the compacted area of fabric, λth is value of beating area in forming of thinned area of fabric. Thus, a clear transition of densities in the strips of fabric with variable density is possible. When moving to a thinned area after fabric moving to the above given value, the value of the fabric supply to comb is reduced to 0.

EFFECT: reduction of abrasive loads on the warp threads in the formation of low-density area of fabric with variable density of filling thread, the possibility making of tissue with variable density of filling thread of a higher quality due to the possibility of obtaining fabric with clearly defined transition of density of filling thread.
