Definitions

  • This invention is concerned with the carding of wool and is concerned in one aspect with modifications of a wool card to facilitate the operation of the card at a speed substantially higher than conventional card speed.
  • worsted card productivity may be doubled or even tripled without detriment to sliver quality or card yield by simply substantially increasing the card speed above the conventional level (Gravolin et al, Proceedings of the Textile Institute Annual World Conference, Sydney, 1988,
  • French patent publication 2232626 discloses a VM removal unit in which
  • an enlarged morel roller accommodates a pair of burr-beaters separated by a reverse worker/ stripper carding unit which functions to invert the web on the
  • SUBSTITUTE SHEET morel mesh to bring the shives and burrs which lie on the inside of the web at the first burr-beater to the outside of the web for dislodgement by the second burr- beater.
  • the invention accordingly provides a wool card having at least one and preferably two 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 said units, is fitted with a plurality of burr-beaters, preferably two, arranged about the morel roller so that the fibre web is fed directly along the morel roller from one burr-beater to the other substantially without intervening inversion of the web or displacement of vegetable matter therein.
  • the wool card further includes a swift and an associated double doffer arrangement including a pair of doffer rollers by means of which the fibre web is doffed from the card.
  • the invention also provides a method of wool carding comprising directing a fibre web along a wool card which includes at least one burr-beater morel unit for the removal of vegetable matter, characterised in that the morel roller of said at least one burr-beater morel unit is fitted with a plurality of burr-beaters and in that said fibre web is fed directly along the morel roller from one burr-beater to the other substantially without intervening inversion of the web or displacement
  • the method preferably further includes doffing the fibre web from the card by double doffing the fibre web as two mats by means of a pair of doffer rollers associated with the swift of the card.
  • 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 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 doffer which is in contrast to the single doffer conventionally found on wool cards, is found to be necessary if adequate doffing efficiency is to be achieved at card speeds substantially above normal speeds. It 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 rate or transfer efficiency by 10 to 25% relative to single doffing.
  • the morel rollers 16, 20 are respective components of a pair of vegetable matter removal units 15a, 15b which are depicted in a tandem configuration but may well be separated by one or more intervening rollers. Each morel roller is of conventional construction and has a cylindrical surface defined by a very fine mesh designed to accommodate the fibres of the web but to leave shives, burrs and other vegetable matter exposed.
  • a singe burr-beater 30a, 30b is disposed adjacent the surface mesh at the top of the roller and includes a longitudinally bladed hollow cylinder which rotates very rapidly and
  • each unit 15a, 15b is fitted with a second burr-beater 31a, 31b located between the take-up point on the morel and the other burr-beater 30a, 30b.
  • the two burr-beaters 31a, 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.
  • the morel rollers 16, 20 are typically made larger than is usual in current or previous carding practice, for example at least 450mm in diameter.
  • 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 among the fibres, as in French patent publication 2232626, or indeed to modify the web in any way.
  • the table also shows that the wool loss for the tandem burr-beaters is low and comparable to that of a morel after the first swift or licker. This suggests that wool loss should not be an impediment to operating tandem burr-beater pairs commercially.
