702,460. Chenille; pile fabrics. AHIER, G. C.. CHAMPAGNAT, A. V., and TIRMONT, J. F. M. Aug. 17, 1950 [April 25, 1950], No. 20451/50. Class 142(4) [Also in Group VIII] Chenille. Chain threads 2, Fig. 15, are coated with adhesive at 4 and guided along the surface of a cylinder 16 which may be heated, where they are wrapped by yarn. from bobbins 18 carried by rotating plate 19; the resulting tubular fabric is cut at 24, opened out flat, and cut between the chain threads. Instead of applying adhesive at the trough 4, the tube of chain threads may pass through an annular chamber 10, Fig. 5, in which the threads run through adhesives. or in which they are sprayed with adhesive. In another arrangement, Fig. 15. adhesive-coated chain threads 2 are fed through the middle of the tubular fabric, yarn from cheese 50 being wound on as the chain threads return along the outside of a cylinder 16, the adhesive being set by a heating cylinder 62 or by hot air. A generally similar machine is disposed vertically, a shaft carrying the cheeses being hydraulically retractable below the floor to facilitate replenishment of the yarn. Another machine is similar. to that shown in Fig. 1, but the wrapping yarn comes from . cheese mounted on a hollow shaft through which the chain threads pass. A cutter roll 26, Fig. 13, cuts between adjacent chain threads, the pile tufts of the resulting chenille being erected by passing the threads along , grooved plates 32, which may be heated, and whose grooves converge to bring the threads close together. Size or a cationic soap may be applied before the pile is folded up. A pattern may be printed on the fabric before cutting it into chenile. Pile fabric, Fig. 13. A backing 35 of felt or rubber is coated with adhesive at 40 and is applied to the chenille. at a roll 34, pressure being applied by a roll 41 and a belt 42. A second, uncoated backing may also be applied, in which case the first backing is porous so that the adhesive spreads to both sides. The chenille from several machines may be brought together and applied to a single backing. In another arrangement, Fig. 22, a backing sheet 35, cut to size so as to completely cover a roll 34, has chenille threads 33 wound on it helically, the threads being cut along the meeting edges of the backing.
