When the piece is woven it will be as shown at A, B, or C ([Fig. 194]) and must next be cut into strips midway between the ribs. Sometimes this is done in the loom as the cloth is being woven, by having cutting knives arranged to divide it as it passes over the breast beam; but it is usually taken off in the piece and cut afterwards in a machine for the purpose. The piece is fed through rollers in the cutting machine over a grooved roller, shown at B ([Fig. 195]), the grooves being at such a distance apart that the ribs of the piece will fall into them. Above this roller is a set of cutting blades fixed in a spiral form round a roller; one of these blades is shown at A ([Fig. 195]), with a section of the roller. The blades are set at such a distance apart that when revolving they fall into the cuts in the roller B, and running at a high speed they sever the piece into strips as it passes through the machine.
So far the process is alike for all classes of chenille work. The weft is now in strips similar to that shown at A ([Fig. 196]) if for carpets, and much smaller if for curtains or shawls. For ordinary chenille the weft is next twisted so as to make the projecting fibres stand out round the rib or core, and when finished it has the appearance shown at B ([Fig. 196]). If for carpets, the fibres are turned up so that all will project in one direction, as shown at C and in the cross-section at d. This is done by running the strips over a grooved roller, as C ([Fig. 195]), which is heated with steam, and as the projecting ends are doubled up by the grooves in the roller the heat sets them in this position. The weft is now prepared, and is wound on bobbins and woven in large shuttles.
