357,089; Divided and this application February 10,4934; Serial June 30, 1928 1 No; 710,705.. In France 4 can. (01. 154-4) ma prior Patent No. 1,731,591, granted octo- Berle, 1929, I- described artificial furs, especially imitation astrakhan, obtained by affixing "gibboiised chenille on a packing made of tissue,- fabric or other suitable material.

Chenille is a product consisting of a coie mad of any textile material, cotton for instance, around which are crosswise-'arrangedfibers, also made of any textue material, (silk, wool, etc.)

Gibbousingf is an operation that consists in laying circularly the cross fibers of the chenille around their core by passing them through suitably heated revolving tubes.-

:"Tne object of this invention is toconstructa machine for making furs imitating naturalastrakhan, according to the process described in my prior application No. 357,089, filed'April 22, 1929, Patent No. 1,950,416, granted March 13,1934, of which the present case is a division; such rocess consisting essentially in previously cutting up suitably gibboused chenille or'like'material into bits of any desired shape and size, and in applying such bits on a backing made of fabric,- hide orother materialcoated with a sticky "coating such as, for instance, rubber cement, so that the saidchenille bits'may be positioned in any order and according to any arrangement whichmey be preferred, permittingan efieot to be obtained which as nearly as possible resembles the natural fur. The chenille employed may have been subjected to more or less marked gibbousing.- Preferably ln order to-obtain a final product offering closer resemblance to astrakhan, and, particularly to increase its strength, I start with a chenillle having a section or width 'of 21 m m-.;or more, previous to gibbousing, which sectlonI- reduce-by gibbousing, to '7 m. m., a ratio given mainly as an indication and variable according to the amount of curling imparted to the fibers by winding them more or less tightly around their core. When such winding extends beyond a complete circle formed by the fibers around their core, considerable advantage ensures overincomplete gibhousing. g

In the accompanying drawingsi Figurel isa general side elevation of a machine for carrying out'the invention;

Fig. 2 is an enlarged detail view of the chenillecutting mechanism;

Fig. 3 is also an enlarged detail view, showing the driving and conveying device for the chenille bits, and their crowding and distribution, previous to final application, on a backing;

Fig. 4 is a detail view illustrating the gumming device and the device for retouching the chenille bits on their backing before the'latter is wound.

A machine constructed in accordance with my invention comprises essentially a frame I, one of the ends of which carries the mechanism for cutting the chenille. Said mechanism is fitted with a conveyorband 2 runningover a lower roll 3 and over two rolls 4 and 5. At there is provided 2.

cylinder permitting the chenille to pass between band 2 and aglass plate 1 which will be hereinafter described. v i

Said conveyor band 2 is driven by one of the rolls 3, 4; or which is rotated by any suitable transmission means. Above and at each side of band 2 are positioned adjustably spaced plates 6 on'which rests the glass plate 1 held, for instance by a cross-strap 8.

Said conveyor band 2 is combined with a second conveyor-band 9 that passes over rolls I0 and II carried by frame I. This band 9 is covered, for a distance a-b, by the glass plate 'I and, together with said plate, by a heating surface .|2, held by another cross-strap I3, Said band 9 is driven, for instance, by means of a pulley M, at a speed lower than the traveling speed of band 2.

In front of the second band 9 therelis located 1 a circular blade I5 rotatedby a suitable motor (not shown), which blade is designed to ,slit the chenille asWillbe hereinafter-explained. Below said blade is located a chute 16 leading to a revolving drum ll, the wall l8 of which is perforated. In front ofthe abovedescribed system extends another conveyor band 19 running over two rollers 20 and 2 I, and kept under proper tension by means of a' suitabledeviceZZ. Motion is imparted to this band I9 by roller 20' itself driven by-a belt transmission 23. On the side opposite the driving roller EOthereis provided, above band 19, a pressure roller 24 the ends of whichfreely rest in suitable bearings 25 (Fig ure 3) carried'by frame I. Band l9, like the conveyorbands of the cutting mechanism, is covered along its sides by guiding members 6. Immedi+ ately in front of roller 24 there is arrangedand heldby a. clamp or cross-strap 26 a plate 1. made of glassor of any other transparent material. Said plate 1' also covers along the whole width thereof, another conveyor band 28 which runs over a roller 21 parallel with roller 2| and somewhat spaced therefrom. Said band 28 is provided, like the foregoing one, with guiding members 6 and it runs over a second roller 29 and over a tensioning roller 30 (Figure 1). Rollers 2| and 21 are mounted on supports 3| and wherever convenient on the machine. It is guided by a series of rollers 35, then 'passes through a suitable gluing device 36 and next runs over a roll 31 whence it passes toroll 38. From roll 38 it goes over'another roll 39, the periphery of which is provided. with paddles.

Next, it passes through a suitably 'deSig'ned'de vice the duty of which is to fill up with any powderized textile the gaps between the stuck-0n inbefore explained.

chenille bits. Said powdering device, housed within a casing 40, is composed of a drum 4! containing the aforesaidpowder and having a perforated wall (not shown). Said drum is revolved by a suitable transmission 42 driven by pulley 43. On issuing from casing), backing 34 goes to a suitable winding device 45 revolved by a belt transmission 45 from pulley '43. J It should be-noted that where it passes-through casing 46 the backing 34 furnished with chenille is subjected first to the action of a beater 46 which assists discharge of the powder'on' the sticky fabric ground between the chenille bits. Said backing next passes over another beater 41 intended to rid it of the excess powderwhich it may have received. -It should also be noted that,'p'revious to entering'the powdering chamber 49, said backing followsan inclined path which is clearly seen in Figures 1 and 4,-and wherealong may be retouched by hand, if required, the arrangementof the chenille bits on the sticky surface which has not as yet become dry. A suction funnel 48 is provided so as to lead out the objectionablefumes from the rubber 'cecompressed. It then comes into contact with the second conveyor band 9 which is moving along at a speed slower than the travelling speed of band 2. Due to. this slowing down, the chenille forms a succession of bends or loops,

.and while in that condition it is carried along by the second conveyor band 9 under the heating surface l2, the heat from which acts on it after it has left the cutting-up mechanism. It

' then comesinto contact with blade I51which cuts it up, the bits falling intochute l6 and thence into drum l1, l8. Said drum deposits the bits, rid of their impurities, on conveyor band l9, on which they can then be properly 'distributed either by hand or mechanically over thewhole surface of conveyor band l9, care being taken bits are crowded towards end l9 of band 19. Said bits, so crowded, come into contact with band 28;.whereon they are automatically distributed in the proper manner. At 28' they meet the backing 34 which has been coated with glue at 36 and adhere thereto. Said backing, so

treated, next travels along'the above described path to reach the powdering chamber and nextthe ,winding device 45. Retouching of the chenille bits iseffected on the sloping portion previous to entering into chamber 40, as here- It'shouldbe noted that backing'34 and-band 28 oughtnotbe driven at the same speed. .SaId drive is obtained bymeans of apinion 43' se-, cured to the end of cylinder 29 of band 28 and in mesh with another. pinion 431', secured to 'I'wish it to'be clearlyv understood that the abovedescribed embodiment is in no, way ,limitative and that any constructional modifications and changes may be introduced without depart-,
