Abstract
A wool card has at least one burr-beater morel unit (15a, 15b) for the removal of vegetable matter, the morel roller (16, 20) of which is fitted with a plurality of burr-beaters (30, 31), preferably two, arranged about the morel roller (16, 20) so that, in operation of the card, the fibre web is fed directly along the morel roller from one burr-beater (31) to the other (30) substantially without intervening inversion of the web or displacement of vegetable matter in the web.

Disclos~ire_o~ ~ke Invention .
It has been surprisingly found, in accordance with the invention, that enhanced vegetable matter removal efficiency can be obtained by fitting one or 10 both morel units of a card with a pair of burr-beaters in which the web travels directly from one burr-beater to the other without intervening treatment by a worker/stripper carding unit. It has been further found that, contrary to the expectation that vegetable matter removal efficiency must inevitably deterioratewith substantial increases in card speed, the provision of such an arrangement 15 results in the restoration of VM removal efficiency to a value close to the efficiency of conventional cards working.at conventional card speeds.: .
The invention accordingly provides a wool card having at least one and . : preferably tvo burr-beater morel units for the removal of vegetable matter, characterised in that the morel roller of said at least one unit, or one or each of .20i said units, is fitted with a pluralityof burr-beatersj preferably two, arranged about .the morel r.oller so that the fibre web.is fed directly along the morel roller from one burr-beater to the other substantiallywithout intervening inversion of the web .n:f ~i or: displacement of vegetablè matter thereinsi .

, The invention will now be further described, by way of example only, with 10 - reference to the accompanying drawing, which is a diagrammatic side elevation of a worsted card in accordance with the invention.
The illustrated card 10 is of known general configuration and comprises a series of main cylinders including, in sequence, a licker 14, a breast 18, a first morel 16, a second morel 20 and a swift 22. The licker, breast and swift have the 15 ~ usual stripper/worker carding units 24 and doffing from the swift is achieved with a double doffer arrangement 26. The fibre web is fed along the sequence of cylinders, doffed as two mats by the successive doffer rollers 26a, 26b, and then converged from the double doffer by a cone (not shown) to form. sliver. ..
The double dofferj which is in contrast to the single doffer conventionally 20 found on wool cards, is found to be necessary if adequate doffing efflciency is to ~ ,be achieved. at card speeds substantially.above- normal. speeds.~; lt has also been . found.that double doffing helps overcome:.problems arising from increased layer thickness.or fibre density at~higher card speeds, and:enhances~.card.production r~at.e~o,,r~transf,er5eKlcien,cy~by lO,to 25.~o~reladve.to single.:doKmg.

acts to sweep the expos`ed vegetable matter into an adjacent tray for recovery and disposal. In accordance with the present invention, however, each unit 15a, 15b is fitted with a second burr-beater 31a, 31b located between the take-up point on 5 the morel and the other burr-beater 30a, 30b.
Most conveniently, the two burr-beaters 31 a, 30a; 31b,30b of each pair are of substantially conventional construction and are typically identical, including the usual longitudinally bladed hollow cylinder and an adjacent longitudinally extending tray. To physically accommodate the additional burr-beater, the morel 10 rollers 16, 20 are typicallymade larger than is usual in current or previous carding practice, for example at least 450mm in diameter.
It will be noted that the fibre web is fed directly along each morel roller 16, 20 from the first burr-beater 31a, 31b to the second 30a, 30b. No intervening provision is made to invert the web or otherwise displace the vegetable matter 15 among the fibres, as in French patent publication 2232626, or indeed to modify the web in any way.
Experiments have been conducted to ascertain the effect of a second burr-beater on the VM removal efficiency of a morel unit in a wool card operated at ~ .. a card speed substantially above normal card speed. More specifically, a t~vo swift 20 .Thibeau card was modified by substituting a 510 mm diameter morel roller for..: the roller of the second morel (normally 360 mm) and fftting two instead of one burr-.beaters to this second-morel. For the purposes of the experiment, the - modified second morel:was operated as a first morel by increasing the fibre loading to..that o'a normal first mo'rel while disconnecting the first morel burr-..25~t .beater. In a series of experiments, the morel roller was successfully operated at a norm'al speed of .95 m/min and at a'substantially higher speed of :207 'm/min.Two~burr-beater~speeds, 1200 and~2200 rpm .were used.~Therresults are n summarised separateily in ~able l for shive and burr. ~
