GARDING MACHINE.

Application filed February 17, 1927, Serial No. 169,017, and in France February 19, 1926.

My present invention relates to carding machines for preparing textile material.

Its object is to facilitate a better clinging or hooking of the fibres by the card clothing, as

5 well as to allow the fleece to become lengthened and the fibres parallelized.

To this end, my invention consists, in combination with the usual cylinders and rollers in carding machines, chiefly the fore rollers, such as licker-in or breakers, in said machines, of the supplemental use of one or more brush-rollers acting on that part of the surface of said fore rollers carrying the fibres to be worked upon. These brush-rollers, hereinafter called drawing-cleaners", rotate in the same direction as the corresponding drum, cylinder or roller with which they are combined, exerting a brushing action on the fibres carried on by the corresponding cylinder or roller, whereby they not only remove certain impurities contained in the fibrous material, which are thus ejected out of the machines, in front of said brush-roller, and then collected by any appropriate means, but also to free the fibres from burrs without these latter being crushed.

Any one of these drawing-cleaners may be either preceded or followed by any known carding and cleaning elements such as drivers,

cleaners, workers and other like rollers or else they may be used in lieu of the drivers used on certain breast-rollers.

Each drawing-cleaner has its surface covered with a brush-clothing of any suitable type and material. It can be constituted for instance by a continuous brush-fillet or ribbon wound in a spiral. The said brush roller may also be covered in view of stripping auto.- matically the fibres drawn along by it when they return to the swift drum, with bands of ribbon-shaped brush coverings disposedalong its generatrices or along helical lines, these band coverings being separated by uncovered intervals which allow the stripping of the brush at the said return of the material to the drum. It should be well understood that any cylinder, the surface of which is alternatingly bare and covered with brush clothing either checker-wise or in any other manner constitutes a modified form of my invention, the bristles or wires of the brushes considered being of any suitable material, according to desire, even of metal and being mounted on any suitablefoundation or even set directly on the cylinder.

Lastly, in the case where the brush drawing cleaner rollers are covered with a spiral Wound, brush clothing and also when the fibres of the material to be treated are comparatively long stapled or of a special kind with any kind of brushes clothing as dis closed hereinabove, the stripping may be elfected by an auxiliary stripping-roller covered with any suitable card clothing and rotatmg in a suitable direction with a suitable speed; this auxiliary stripper may be disposed either before or after the drawing cleaner with which it cooperates, according to circumstances; this combined arrangement maybe completed moreover, chiefly in the case when a too high speed of the drawing cleaners prevents the fibrous material being conveyed directly to the drum or cylinder, through the stripping cylinder by means of a1 transmitting roller working as combing roller and restituting the material to the drum or cylinder.

In the case of combined arrangement com-.

ferent but is preferably opposed to that of the drawing cleaner.

In the present case where the combing action is realized by the auxiliary stripper, the card clothing of the transmitting roller may be of any kind and may be either an ordinary one or preferably a brush clothing metallic or not.

I have described hereunder, by way of example,in order to allow my invention to be fully disclosed. a certain number of forms of execution which are diagrammatically shown on appended drawings wherein:

Fig. 1 is a side View of a licker-in of a carding machine cooperating in combination with vthe drawing-cleaner according to my invention.

Flg. 2 15 a side v1ew of a carding machine main cyhnder, swift or drum, cooperating in combination with a drawing cleaner and a rear auxiliary stripper.

Fig. 3 is a side view of a carding machine main cylinder, with a drawing-cleaner and its fore auxiliary stripper.

Fig. 1 is a side view of a main cylinder or drum with a drawing-cleaner and its auxiliary stripper disposed rearwardly of it, to which parts is added a transn'iitting roller.

Fig. 5 is a View similar to the precedent with the difference that the auxiliary stripper is placed in front of the drawing-cleaner, as in F 3.

Fig. 6 is a modified form of the device shown on Fig. 4.

Fig. 7 is a view similar to the precedent with the difference that the auxiliary stripper is placed in front of the drawingcleaner, as in Fig. 3.

In Fig. 1 of the drawing is shown a carding Ina-chine comprising the swift or main cylinder 1, the cleaner brush 2 and also the usual carding elements, driver 5, cleaner 6 and worker 7 The cleaner brush 2 rotates in the same direction as the swift 1 and as the cloth of fibres pass under this brush, said brush lengthens and draws the fibres and in the card clothing of the swift 1, ejecting the impurities into the container 9 while at the same time taking off with it a certain amount of the more bushy fibres which it returns back to the swift after one revolution. The course of the fibres is indicated by 8. The burrs and fibres are projected by centrifugal force and do not have to pass across the fleece since the cleaner brush 2 only takes off with it a certain number of more bushy fibres which cling to the hairs of the brush while the impurities cannot cling thereto.

In Figure 2 is shown the swift 1, the cleaner brush 2, a stripper roller 3 located to the rear of the cleaner brush 2, the course of the fleece or lap being shown at 8. The fleece of fibres 8 follows the same course as in Fig. 1, but the stripper 3 takes off the fibres from the cleaner brush 2 and gives them back to the swift 1.

The essential difierence between Figs. 1 and 2 is that the latter figure shows the taking up by an auxiliary stripper 3 of the certain number of more bushy fibres above referred to as being entrained by the cleaner brush 2, the major portion of the fleece 8 continuing its course on the swift 1 as in Fig. 1.

In Fig. 3 is shown a similar combination of parts except that the stripper cleaner brush is in front of the roller 2, the course of the cloth of fibre being indicated at 5'. The cleaner brush 2 lengthens the fibres 5 in the card clothing of the swift 1 and takes off the bushy fibres which are taken by the stripper 3 to be given back to the swift 1. I

The forms of execution according to figures 2 and 3, are of particular advantages when the speed of the drawing-cleaner is comparatively slow with reference to that, more rapid, of the swift drum or main cylinder in which case the speed of the auxiliary stripper is intermediate between that of the cleaner and of the drum.

In Fig. 4 is shown in combination with the swift 1, the drawing-cleaner roller 2, the stripper roller 3 and the transmitting roller 4. The course of the cloth of fibres being indicated at 5. This arrangement being of special interest when the speed of the drawing-cleaner is too high to allow, in the case of Fig. 2, the auxiliary stripper to be given a speed whereby it may first strip the cleaner and then restore the fibrous material to the drum or main cylinder rotating at an ordinary speed; in this case the combing action of the transmitting roller rotating at an intermediate speed will allow the material to be returned to the drum or swift.

In Fig. 5 is a modification of Fig. 4: in which the stripper roller 3 and transmitting roller 4t are placed in front of the drawingcleaner roller 2. The course of the cloth of fibres is shown at 5.

In Fig.6 is shown a modification of Fig. l, where the combing action is performed at the point of contact between the auxiliary stripper and the drawing cleaner. In this case the stripper rotates slowly and the transmitting roller is covered with any suitable cardclothing, either an ordinary one or a brushclothing, metallic or not.

In Fig. 7 in which the stripper roller 3 and the driving roller 4 are placed in front of the drawing-cleaner roller 2, the course of the cloth of fibres being indicated at 5.

As already stated the arrangements shown may be used either alone or in any suitable number, the arrangements being similar or not on the several carding machine main-cylinders or drums.

lVhat I claim is:

1. In a carding machine, the combination with a rotating fibre treating element of a carding machine, of a supplemental brush roller adapted to act as a cleaner to cooperate with the fleece on a carding machine to sep arate the trash therefrom, and cooperating with such element and rotating in the same direction as the said element, the brush roller acting on the part of the surface of the treating element which carries the fibrous material to be treated and a receptacle to receive and hold such trash. 2. In a carding machine as claimed in claim 1 1n whlch the supplemental brush roller com prises a fabric having thereon brush bristles 1n groups, sald groups being spaced from each other. a

In testimony whereof I aflix my signature.

GUSTAVE GLARISSE.
