Abstract

System and method for on-loom fabric inspection includes an imaging device collecting images of a weaving area of a loom, a frame grabber receiving images of a fell-pick of and sending compact image data packages to an image processor. Irregularities may be detected by comparing a digital string representing the characteristic sequence of warp-risers and warp-sinkers along the fell-pick with a corresponding row (901) of required warp-risers and required warp-sinkers in a reference matrix (900) representing a required weaving pattern. The digital string may be a sequence of Boolean values.

Description

technical field [0001] The present invention relates to a system and method for fabric inspection on a loom. In particular, the invention relates to row-by-row weft yarn inspection. Background technique [0002] Weaving is the most popular way of making fabric. It is primarily done by interweaving two sets of orthogonal yarns (warp and weft) into regular and cyclical patterns. Weaving involves repeating the operations of shedding, picking and beating up in sequence. All these processes are usually carried out by looms. Shedding is the process of raising or lowering the warp yarns to create a space called a shed through which the weft yarns can pass. Picking is the process of inserting the weft yarn through the shed so that it intersects the warp threads. Beat-up is the process of pressing the weft yarn against the fell, where a new weave is formed. [0003] Fabrics experience many failures during the weaving process. Braid failures include broken yarns, double yarns, ...
