Abstract: 785. Cowell, A. G. Jan. 11. C h e n i l l e for carpets and other pile fabrics is woven in the ordinary manner, and the take-up mechanism is regulated so that the number of wefts in a given length corresponds with the count of the reed used in the setting-loom in which the chenille is woven as weft to form pile fabrics. After each series of strips, representing one row in the design paper, a strip of cloth of closer texture, termed a " droplea," about one-half inch in length is woven. The chenille cloth is cut iato strips in the usual manner, and is wound flat in repeats on to bobbins. Chenille fabrics ; carpets.-The chenille is woven as weft into two, three, or four shot fabrics. Two body warps d, Fig. 3, are crossed alternately over and under the body wefts g, and a binder warp f passes under the wefts between the chenille wefts b and over the chenille wefts, which are laid flat on the body warps over a ground weft with their tufts between these warps, so that the tufts can be turned down between them. Looms, pile-forming in; shuttleless looms ; weft, supplying; weft tension, regulating ; reeds.-The pile fabrics are woven in a band or power petting- loom. The body warps are shed by healds, and the binder warps eitt er by healds or by needles on a needle-bar actuated in the usual manner. The reed dents are only sufficiently far apart to allow the warps to pass between them, and the reed may be open at the top. The chenille wefts are drawn from a rotatable bobbin placed parallel to and near the selvedge, and pass between two friction rollers in order that they may be properly tensioned. In hand-looms, the wefts may be inserted by means of a stick with an attached clip, and in a power loom by a horizontal arm fitted with a clip and actuated to move laterally across the loom in the ordinary manner, the " droplea " at the end of each weft being fixed in the clip and the weft drawn across thereby. The tufts of the chenille weft are forced down between the body warps by means of a suitably-actuated double comb l, Fig. 9, of which the teeth correspond exactly with the dents in the reed. The ends of the tufts may be prevented from springing up after the comb rises, by means of a clip extending across the loom below the warps, and so placed that when the comb l descends the tufts b are forced between the jaws of the clip, and engaged thereby. The reed n is then moved forwards, and the clip follows the pile threads towards the fell, and is dropped at the proper time to allow the reed to beat up. The clip may be dispensed with, and the comb l arranged to slide up and down in a pivoted frame. While the comb is depressed, the warps f are lowered, and a weft g is inserted. The reed is then moved forwards, and beats up the weft g close to the comb l, which is at the same time moved forwards towards the fell. When the comb is raised, the free ends of the pile tufts are prevented from rising, on the one side by the fell, and on the other side by the weft g. In the Provisional Specification, it is stated that a pair of brushes may be used instead of the comb l to force the pile tufts down between the warps d. The brushes may be circular and be made to rotate in opposite directions when lowered.
