CARDING ENGINE FOR CARDING ARTIFICIAL SILK ANDSUGH LIKE MATERIAL.

Application filcd'Novcinber 10, 1926, Serial No.

Our improvements have reference to carding engines for carding artificial silk, or it might be artificial wool or the like, where the fibres are cut to one uniform length and where it is not requisite that the card shall exercise any particular cleaning effect or have to deal with very short and long fibres at one time.

The object of the invention is to save waste or prevent loss of' the valuable material being dealt with, and we effect this by providing and utilizing a revolving covered roller or brush covered with wire or dents or bristles or fibres and which we locate near to the licker-in and there use on the travelling chain of flats. This roller is set to the flats and the cylinder wire. that is contiguous to the dents and is set-in to the same if required, and, by its action, fibres remaining on the travelling flats after leaving the cylinder are not stripped off so as to become waste but are returned by said covered roller to the main cylinder for incorporation or blending with fibres entering the card and not yet operated on by the flats. As thus, the fibers stripped from the flats are put back onto the incoming new material. The flats which are in carding contact with the main cylinder travel towards the licker-in, or they may travel in the contrary direction. Such a single roller arrangement serves for working with some classes of fibre but with other classes of fibre we use in combination with the before described covered roller (and to effectively deal with any fibre still remaining on the flats and depending or hanging down) a revolving brush which is set to the revolving flats and the before described roller, the same having bristles, dents or wires, fibre or other clothing and the bristles may be set slightly into the flats and be cleared of' any fibre by the before described roller and the fibre returned to the main cylinder.

Provision is made for driving both roller and brush, the latter lying in front of the former looking from `the front of the card. Plain under sheetings for the licker-in and main cylinder are also preferably provided with advantage, as later indicated.

The drawing accompanying and forming part of.' this specification is a diagrammatic side view of a machine illustrating one embodiment of our invention.

Referring' to the drawing, according to our invest-rari aus. in aannemen with mi/arf 147,430, and in Great Britain January 5, 1926;

ing` flat cards :for the indicated purposes, we no longer use a [iat stripping comb which ren'rovcs the material in the form of flat strippingsf7 but we apply :i revolving covered roller, or revolving brush (t suitably clothed and this is located near to the lickerin and intermediate of the flats c and main cylinder d and this covered roller a. is mounted and driven so as to strip the flats and deposit the material on the main cylinder whereby the valuable strippings are deposited on the new material being carried up by the main cylinder. In combination with the covered roller a. just described, and in connection with same and the flats we employ a revolving brush or stripper ai', the covered roller fr and the brush (1, revolving in the same or either direction. The flats over the cylinder in this case revolve towards the licher-in.

iVith the nocd for economy we can with advantage return the artificial silk or material of' regular or oven length of fibre and 'free Afrom impurities by a revolving covered device a. which simultaneously strips the flats and feeds the saved material for blending or combining with fresh supplied material. In the arrangement herein illustrated. however. the action of the combined revolving brush a along with the covered roller a deals effectively with any fibres cscaping the first stripping action.

Also, with the object of effecting further economies. we prefer to dispense with mote knives and grids below the licker-in 7) and to use a plain bent sheet or sheets 7) of metal plate in lieu thereof, the same being supported from setting brackets and being adjusted to leave a narrow space between the plain sheet and the revolving lickenin so that again material cannot escape. and economies are effected. Also, for the purpose of' preventing waste of fibres, a plain bent sheet or sheets d of metal plate in lieu of a grid may be used below the main cylinder (l and supported in any convenient manner.

The features of our invention become feasible for effective working by reason of' the fact that the material dealt with carries no impurities and there is no great variation in the length of fibres being carded at any one time. The arrangement described allows us to save and Tri-introduce automatically into timpani. runter-ini whim vente iran-'eist tra aaa-,rai
