Definitions

  • the invention relates to all-steel sets for rolls and / or drums of cleaners, carding or carding, which rollers or drums have a higher peripheral speed than upstream in the fiber flow direction, the all-steel set having teeth with a positive breast angle of ⁇ 0 °, see, e.g. EP 1 099 783.
  • the rolls involved here are, for example, lickerin rolls, turning rolls or transfer rolls on carding machines or carding machines, as well as the drum of a carding machine or carding machine. These rolls or drums actively take fiber raw material with the front edge of the breast angle of the teeth of the corresponding all-steel set.
  • the invention has for its object to provide an all-steel set of the type mentioned above, which eliminates the disadvantages to be observed in the prior art while maintaining good takeover properties.
  • the teeth have a head angle which is> 85 °, preferably> 87 °, the length of at this angle extending from the tooth tip to the back of the tooth head at least 15% the length of the tooth pitch corresponds.
  • the head angle of the tooth is 90 °. This results in the same conditions being present on all teeth even after the set has been ground, which in turn leads to an improvement in the carding quality.
  • the length of the top surface corresponds to at least 25% of the tooth pitch.
  • the length of the top surface corresponds to at least three times, preferably five times its width.
  • the length of the head surface is greater than or equal to half the tooth height, measured from the tooth base to the tooth tip. This results in a relatively low set, which surprisingly leads to good Kardierönn. It is particularly preferred if the length of the top surface corresponds to the tooth height.
  • the tooth back adjacent to the head surface encloses an angle between 20 and 30 °, preferably 25 °, with the following tooth face.
  • This opening angle between tooth back and tooth face tends to be smaller than in the kits of the prior art; however, it is sufficient to ensure trouble-free transfer of the fibers from the upstream roller in the working direction.
  • FIG. 1 shows a schematic representation of a carding machine with a drum 1, feed rollers 2, a licker-in 3 and turning rollers 4.
  • the circumferential direction of rotation of the rollers is shown in FIG. 1 by arrows.
  • the clothing described below relates in each case to such rollers or drums which actively take over fibers from the rollers arranged upstream in the working direction.
  • the turning rollers 4 and in particular the drum 1 are shown.
  • Fig. 2 shows a section of a sawtooth wire of an all-steel clothing, as provided for the drum shown in Fig. 1. It is a sawtooth wire with a total height of 2mm and a pitch, measured from tooth tip 5 to the next 5 'of 1.7mm. The measured to the vertical breast angle ⁇ of the tooth face 6 is 40 ° in the embodiment shown here. Unlike previously known all-steel sets, the tooth tip does not directly adjoin the tooth back 7; Rather, a top surface 8 is initially provided. The angle of the head surface ⁇ , again measured to the vertical, is 87 ° in the embodiment shown in FIG. The length L of the top surface 8 is 0.5 mm, its width B (see Fig. 3) is 0.07 mm. The tooth height H, measured from the tooth root to the tooth tip 5, is slightly less than 0.5 mm.
  • the included by the tooth face 6 and the back of the teeth 7 angle ⁇ is 24 ° in the embodiment shown here.
  • FIGS. 4 and 5 show a further variant of a sawtooth wire for an all-steel clothing according to the invention.
  • the same reference numerals are used as for the previous embodiment.
  • the distance from the tooth tip 5 to the adjacent tooth tip 5 ' is only 1.5 mm.
  • the breast angle ⁇ is only 30 °.
  • the included between tooth face 6 and 7 tooth back angle ⁇ is 25 ° in this embodiment.
  • the two embodiments do not differ.
  • the sawtooth wire shown in Fig. 2 has a larger breast angle, which is basically favorable for a more active Faserübemahme.
  • a long head surface is provided which is almost not inclined and which therefore gives the tooth tip and the entire clothing increased stability.
  • the tooth geometry practically does not change even after blending the set, so that on the one hand on all teeth practically the same conditions exist, and on the other hand, the carding does not change even after grinding the trimmings.
  • the mounting of the sets is done in a conventional manner.
