EUGNE LOUIS EZBE'LENT, OF PAB-IS, FRANCE.

PLAITINGMACHINE FOR PRODUCING TEXTILE FABRICS RESEMBLING VELVET.

To all whom it 'may concern Be it known that I, Encinas LOUIS EZBELENT, citizen of the Republic of France, residing at 80 Rue de Belleville, Paris, in the Republic of France, have invented new and useful Improvements in Plaiting-Machines foi' Producing Textile Fabrics Resembling Velvet, of which the following is a specification.

This invention relates to apparatus for the production, on ribbed materials of the kind known in France as velours cristal, of smooth strips of suitable width, means being preferably provided for varying the spacing of said strips. Ribbed fabrics of this kind are, as is known, produced by compress ing the fabric in a moist state on a heated cylinder by means of wires or plates held pressed against the outer surface of the paper covering the fabric and causing the fabric to pass around the cylinder by means of a comb receiving a reciprocating movcment, the teeth of this comb entering spaces formed in the plates or the spaces left between the wires and forming ribs on the fabric by small successive amounts as they feed it forward.

According to the present invention, there are interposed between the fabric and the comb thin pieces of pasteboard or other material which are gripped and consequently carried forward between the fabric and the paper and which when they reach the comb prevent the formation of ribs in the fabric by the said comb. This comb thus only has for its object to move with it at the same time the pasteboard strip and the fabric in such manner that the fabric at the place where the said strip contacts therewith is formed with a smooth part of the same length as the strip of the pasteboard.

In the annexed drawings given by way of example: Figure l is a cross vertical section of a plaiting machine provided with the above improvements. Fig. 2 is a diagrammatical view of a modification in which the pasteboard strips are inserted from the rear of the machine. Fig. 3 is a plan view showing diagrammatically the appearance of the crimped or plaited fabric obtained.

As shown in Fig. 1, the fabric 1 is wound off a roller 2 and the sheet or strip of paper 3 is wound off a roller 4. The fabric covered with the sheet of paper is kept uniformly pressed throughout its whole surface against Specification of Letters Patent.

a heated roller 5 in the usual manner by means of flexible metal plates 6 suitably secured at T and held continuously under tension by means of counterweights S acting on each of them separately. Into the openings or slots (not shown) formed in. the plate G, pass the teeth of a comb 9 to which is iinparted in suitable manner a reciprocating movement so that the fabric is advanced and folded by small successive amounts. Near each edge of the fabric is laterally disposed a pulley 1 0. The two pulieys l0 are keyed on a shaft l1 which receives a slow rotary movement preferably at variable speed by any suitable means such as that hereinafter described. Around these pulleys 10, pass belts l2 these belts also passing around corresponding pulleys (not shown) of the same diameter as the heated cylinder 5 and being loosely mounted on the shaft and on either side of the said cylinder. rl`he pulleys 10 are so located that the upper portions of the belts 12 will be situated in vertical projection between the sheet 0f paper and the fabric. These belts 12 are provided on their outer surfaces with hooks 13 for moving the thin strips 14.- of pasteboard, metal or other material, which are placed into these hooks, over the upper face of the fabric. The belts in their movement in the direction of the arrow carry with them the strips of pasteboard which are finally gripped between the fabric and the sheet of paper and carried therewith in the more rapid movement of the same. Then the strip reaches the comb, the teeth of this latter cease to fold the fabric and act only to push forward the three superposed elements, z'. c. the sheet of paper, the pasteboard and the fabric. As a result throughout the `whole width of the strip of pasteboard the fabric will not be ribbed. The appearance of the fabric thus treated is shown in Fig. 3. It is thus possible to obtain materials in a single piece which while presenting a new aspect agreeable to the eye, have the advantage of using less fabric for the same area. In order to permit of increasing or decreasing, at will, the space between the consecutive unribbed intervals, it is only necessary for example to operate the shaft 1l carrying the pulleys 10 by a variable speed mechanism. Fig. 4:

disk.

shaft 11 and driven by a roller 16 adapted to rotate with a driving shaft 17 on which it is mounted, but capable of being moved along said shaft by means of a fork 19 operated by means of a sliding rod 19a. By displacement of the friction roller 16 relatively to the surface of the friction disk 15, the speed of this latter may be varied, that is to say, the rapidity with which the strips of pasteboard are gripped between the sheet of paper and the fabric and, consequently, the distance between the unribbed parts of the fabric.

lt is obvious that interposition of thin strips between the fabric and the plaiting comb -with the object of obtaining smooth parte in the ribbed fabric may be effected in many different ways, for instance the strips may be inserted at the rear of the machine instead of being inserted at the front as in the construct-ion just described. In one embodiment of the latter arrangement shown diagrammatically in Fig. 2, the strips 14 are placed at the rear of the machine on the ascending portion of the belt 12 passing over the guide pulleys 20. The hooks are in this case formed by claws 13a sufliciently effective to prevent the strips of pasteboard falling during their descending movement at the front of the machine, but permitting, nevertheless of these strips being released when they are pressed between the fabric and the paper, in the same way as in the above construction.

ln the foregoing description, it has been assumed that the strips of pasteboard are inserted by hand, but it is obvious that the machine may be provided with an automatic distributer of any known type.

The strips in lieu of being smooth and of pasteboard may be made of thin metal and may be formed on their lower surface in contact with the fabric, with designs in intaglio or in relief, permitting of the production of corresponding designs on the unribbed parts of the fabric. l/lVith satin material effects similar to those of figured satin may be obtained in this manner.

Having now described my invention, what l claim as new and desire to secure by Letters Patent is:

1. In a plaiting machine, in combination: a. heated roller, means for guiding fabric and a sheet of paper around said roller, plaitingmeans cooperating with said roller and means for inserting thin strips 'between the fabric and the paper, substantially `as described and for the purpose set forth.

2. In a plaiting machine, in combination, a heated roller, means for guiding fabric and a sheet of paper around said roller, plaiting means cooperating, with said roller, endless transporting belts on both sides of the fabric and paper, means for displacing said belts at aV slower speed than the fabric and paper, a portion of these belts being substantially on a line drawn from the line of contact of the fabric and paper and located. inside the angle formed by the latter, and means on said endless transporting belts for holding thin strips of material, substantially as described `and for the purpose set forth. v

8. ln a plaiting machine, in combination: a heated roller, means for guiding fabric and a sheet of paper around said roller, plaiting means cooperating with said roller, endless transporting belts on both sides of the fabric and paper, means for displacing said belts at a variable speed slower than the fabric and paper, a portion of these belts being substantially on a line drawn from the line of contact of the fabric and paper and located inside the angle formed by the latter, and means on said endless transporting belts for holding thinstrips of material, substantially as described and for the purpose set forth.

el. ln a plaiting machine, in combination: a. heated roller, means for guiding fabric and a sheet of paper around said roller, plaiting means cooperating with said roller, endless transporting belts on both sides of the fabric and paper, guide rollers so arranged that a portion of the endless belts extends at therear of the machine, means for displacing said belts at a slower speed than the fabric and paper, a portion of these belts being substantially on a line drawn from the line of contact of the fabric and paper and located inside the angle formed by the latter, and means on said endless transporting belts for holding thin strips of material, substantially as described and for the purpose set forth.

ln testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
