Fabric weft setting or weft setting and pattern setting system and method

Abstract

The invention discloses a fabric weft setting or weft setting and pattern setting system and method. The fabric weft setting or weft setting and pattern setting system comprises a correcting mechanism, a detecting mechanism and a central processing unit. The correcting mechanism comprises a first driving roller wheel, a second driving roller wheel and a plurality of correcting rollers, the first driving roller wheel is driven by a first motor, the second driving roller wheel is driven by a second motor, the multiple correcting rollers are driven by the driving mechanism, the first driving roller wheel is arranged on one side of fabric in the width direction, the second driving roller wheel is arranged on the other side of the fabric in the width direction, and the multiple correcting rollers are arranged in front of the first driving roller wheel and the second driving roller wheel along the fabric running route. The detecting mechanism is arranged in front of and/or behind the first driving roller wheel and the second driving roller wheel along the fabric running route, and the first motor, the second motor, the driving mechanism and the detecting mechanism are controlled by the central processing unit. The first and second driving roller wheels are preferably friction roller wheels with friction surfaces on the periphery. The fabric weft setting or weft setting and pattern setting system and method have the advantages of wide application range of textiles, no damage to fabrics during correction, fast correction response, capability of real-time correction control, high correction precision and good effect.

Description

technical field [0001] The invention relates to a system and method for correcting weft skew, weft bend, flower shape skew and flower shape bend of fabrics, in particular to a system and method for fabric weft adjustment or weft adjustment and flower adjustment, belonging to the technical field of textile equipment and technology . Background technique [0002] Weft skew is the skewed state in which the weft or knitted fabric course deviates from a straight line perpendicular to the warp or wale of the fabric. Bow weft (weft bend) is the weft or knitted fabric course deviates from a straight line perpendicular to the warp or wale of the fabric. Direction forms one or more arc skew states. The weft yarn mentioned in the present invention refers to the weft yarn of the woven fabric or the course of the knitted fabric. [0003] Woven fabrics are made of warp yarns and weft yarns that are perpendicular to each other and are interwoven at a 90-degree angle. The longitudinal yar...

Problems solved by technology

For non-elastic fabrics, after adjusting the angle of the straightening rod, the full-width inward fabric will no longer completely cover the straightening rod, and the fabric will hang, and the weft skew/bend cannot be corrected at all. Therefore, the non-elastic fabric cannot be corrected at all. roller weft

[0015] For high-elastic fabrics, the correction rod or needle wheel does not have sufficient weft strength, and the weft yarn of the corrected fabric is easy to return to its original shape, neither of which can effectively improve weft skew/bend

[0016] In summary, the above-mentioned pin wheel weft adjusting device a
