Definitions

  • the invention relates to a flock storage and a flock feed according Oberr concept of claims 1 and 19.
  • the way in which a card is fed with fiber material has a significant influence on the card sliver produced. Irregularities in the feeding of the carding machine are expressed in the formation of thick or thin areas in the produced sliver. These defects in the strip can only be partially corrected in the subsequent further processing of the fibers up to the finished yarn. They therefore have a direct influence on the final yarn quality.
  • the fiber flakes in the hopper must form a uniform cotton wool. Ie. The fiber flakes must be distributed evenly over the entire width of the hopper to thereby form a homogeneous wadding of uniform density. The fiber flakes are fed pneumatically to the filling shafts.
  • the feeding of the carding machines with the aid of a pneumatic fluff feed does not, however, guarantee a sufficiently uniform feed of the carding machine or of the associated filling chute.
  • This problem has long been known and has been solved in that the filling shaft of the card was equipped with a feed device, which divided the actual hopper into two superimposed manholes (top and bottom shaft). Thanks to the feeding device, the fiber flakes move evenly from the upper shaft into the lower shaft, regardless of the uniformity of the delivery of the flakes, when the filling shaft is fed with fiber flakes via the pneumatic fluff feed. This results in the lower part of the filling shaft, a homogeneous Wattenvorlage, which is suitable for feeding the card.
  • Flake reservoirs which are formed from an upper and a lower shaft part, represent a well-known state of the art in spinning plants. Examples of such reservoirs can be taken from the following patents: US 4499633; US 4593436; US 4656694; US 4697309; US 4731909; US 4776066; US 4968188; DE 2939968; DE 3904853; DE 3904878; EP894878.
  • Such Flocken agenda are today usually provided with a feed roller, which is provided between the shaft parts and the template passes in the upper part of the shaft from an opener or opening roller. The at least partially dissolved flakes are passed from the opener roller to the lower shaft part.
  • the lower shaft part is normally arranged substantially vertically, wherein a horizontal arrangement z. As proposed in DE-C-3928280.
  • EP-B-866153 and / or EP-A-989213 In the period before 2020 it is unlikely that a carding machine for the spinning mill will have a working width> 2m.
  • the carding of a spinning works but with several cards, which must therefore be produced as inexpensively.
  • These machines are designed to process cotton. They are therefore normally used as traveling Ckel-cards executed in order to fulfill a Schmutzausscheidungsfunktion.
  • the present invention relates to a filling shaft for the carding of a spinning plant, d. H. a plant designed for the production of yarn.
  • the carding machine supplied from the hopper must produce a sliver that is suitable for further processing into a yarn.
  • the terms "carding” and “spinning” are accordingly limited here - "carding” for the production of nonwovens are excluded
  • it is not always easy to determine from the patent literature whether the stated hopper constructions are really suitable for yarn production and / or for the Nonwoven production are suitable - many design principles are generally claimed (these remarks are also valid for different examples in the previous chapter).
