Definitions

  • the present invention relates to a card with one, an all-steel clothing having drum and a revolving lid apparatus with a garnish having Flat bars, the flat set having check marks.
  • the angle is between a parallel to the flat bar level and the rear grinding surface the check mark measured.
  • the advantage lies in the simpler one Regrind the check marks and secondly that over the entire service life a flat set the Kardiermusic is consistently high.
  • the term Schuschleiff Chemistry is used in the present application also when the Angle is 0 degrees and thus actually no relief is present.
  • the regrinding is particularly simple if the relief bevel angle is even is formed, that is 0 degrees. Designed due to the geometrically simple contour the manufacture or regrinding, especially with regard to easy used grinding tools, relatively simple and inexpensive.
  • the back fin surfaces of several side by side on the flat bar attached check mark lie substantially in a plane has this has the advantage of allowing uniform carding.
  • a particularly advantageous geometrical aspect consists in a variant, that a Hinterschliff Colour a length of at least 0.5 times the largest Has cross-sectional dimension of the check mark.
  • Below the largest check cross section dimension can e.g. in a flat fitting the wire diameter or at oval wires meant the long cross-sectional dimension.
  • the cross-section is considered perpendicular to the center axis of the wire. In small Angles for the rear surface make their length particularly positive, because much more material is available.
  • the back ground area can be a length / width ratio of larger 3.5 have. This also ensures that sufficient in the top area Material is available.
  • the back ground area may have a width of less than 0.1, preferably 0.07 mm.
  • the processing resistance in the carding zone be kept as low as possible.
  • the hooks can in the direction of the back ground surface converging side surfaces having a vertical height of at least 1.5 mm to Hinterschleife Chemistry respectively. Partly it is also possible to have this height about 2.5mm or even 3,2 mm to enlarge. This is usually done by a smaller one Angle ⁇ is reached, in which the side surfaces run. This allows regrinding achieve the flat set over a much larger area, without the Conditions at the top of the check mark become unacceptable.
  • Be particularly favorable has been found according to an embodiment, when one between the back ground surface and the front working surface of the hook spanned angle greater than 60 degrees, preferably greater than 70 degrees.
  • the front working surface is the opposite to the machining directions of the drum pointing surface of the check mark.
  • the angle should be less than 90 degrees, preferably 80 Degree, amounts. This further ensures that a tip for carding forms on the hook.
  • Hook made of a carbide alloyed carbon steel used.
  • carbon steel is preferably heat-treatable such that e.g. By the heat treatment carbides form in the surface area, which is the hardening support.
  • the invention is particularly effective if, according to a variant, the total height of the hooks is less than 9 mm. hereby results in an optimal ratio between the cross sections commonly used and the overall height and the expected load.
  • the drum peripheral speed is greater than 1300 m / min
  • a height of the drum set is smaller than 3 mm
  • a breast angle of the teeth of the drum set is greater than 25 ° and in particular greater than or equal to 30 °
  • the foot width of the drum set smaller than 0.8 mm, in particular smaller than 0.7 mm.
  • the invention relates to a flat fitting for insertion into a card according to one of claims 1 to 15.
  • a card 1 is shown. It consists inter alia of a drum 2, which rotates about a center of rotation A in the direction of arrow B.
  • On her surface 7 is an all-steel set. At least part of the surface 7 is with a lid apparatus 3 in operative relationship.
  • the flat rod migrates by means of deflection rollers 4 opposite or in Rotational movement with its flat bars 23 along the drum 2. Between cover set and a drum set a machining gap 4 is present.
  • the check marks 8 are shown enlarged in Fig. 2 in the machining gap 4.
  • the check marks 8 are angled and therefore have a so-called knee.
  • a Longitudinal axis 9 of the hook 8 has opposite to the direction of rotation B of the drum 2.
  • Die Saw teeth, which are mounted on the drum 2 point in the other direction as the prongs 8, which are attached to the flat bar 23.
  • the check marks 8 form in each case a part of the clothing 6 from the flat bar 23.
  • Fig. 2 is in each case one Checkmark 8 symbolic of a flat bar. Inside the flat bar are the tips the check mark 8 arranged substantially in one plane.
  • Fig. 3 is a check mark 8, which in the set 6 of the flat bar 23 of the lid apparatus 3 application is shown, which is made of an oval wire is.
  • the check mark 8 comprises a main body 10, on which a Abkantteil 11 with the top 12 connects.
  • the bending part 11 By the bending part 11, the said longitudinal axis 9 runs.
  • the bending part 11 has at least two areas, wherein the front portion of the tip 12 with the sharp makes a sharp end.
  • the base body 10 and folding part 11, up to a machining edge 14 have an oval cross-section.
  • the tip 12 has a top on the top Schuschleife Chemistry 13 on.
  • the tip 12 has side surfaces 15.
  • the Side surfaces 15 are made flat by a side grinding.
  • the back ground area 13 is precisely ground in a relief angle of 0 degrees. The Schuschliff vom all hooks are thus in a plane parallel to a flat-top plane is stretched.
  • An undercut angle ⁇ becomes between one through the front tip end of two successively arranged check mark 8 extending axis and one through the front tip end extending tangent 18 of the back ground surface 13 measured.
  • the fiber material to be processed is fed to the card or carding machine via feed rollers guided. There it gets into the machining gap 4 between the drum 2 and the flat bar 23. Hooks 8 of a set 6 and a steel set, on the surface 7 of drum 2, separate the fibers and align them.
  • the relief angle ⁇ 0 ° ensures that despite re-sharpening the flat cover remain over the entire life consistent Kardiertownen.
  • the check mark 8 shown in FIGS. 4 and 5 is designed as a double check mark and manufactured by U-shaped bending of a clothing wire.
  • the U-shaped Garniturdraht Cambodia is anchored in a multi-layer fabric construction 19.
  • a metro 20 of the piece of wire extends along the underside of the fabric construction 19.
  • Above the knee 21 each has a check mark to the Schuschliffs Design 13 converging side surfaces 15.
  • the side surfaces 15 run in one Angle ⁇ of about 7 degrees towards each other. It remains at the end of the top 12th a substantially rectangular Hinterschliff Chemistry 13 with a width in the New condition of approx. 0.03 mm.
  • An angle ⁇ , located between the back ground surface 13 and a processing surface 22 spans on the front of the hook 8 is in the present case about 76 degrees.
  • the Schuschleiff Structure 13 is flat designed. Several juxtaposed Hinterschliff vom 13 within a clothing area are arranged in a common plane.
  • the side surfaces 15 have a vertical length from the undercut surface 13 measured from 2 mm up. At this point it should be mentioned that the vertical height at least 1.5 mm and the angle ⁇ greater than 60 degrees, preferably greater than 70 degrees should be. Furthermore, care should be taken that the angle ⁇ is smaller should be 90 degrees, preferably 80 degrees.
  • the length of the Schuschleiff Structure 13 at least 0.5 times the largest cross-sectional dimension equivalent.
  • This cross-sectional dimension is determined by the length of the oval cross-section Are defined.
  • a length / width ratio of the back ground surface 13 greater than 3.5. In the following case, the length is about 0.4 mm, so that a ratio of about 12.5 results.
  • the back ground surface has a width of less 0.1 mm, preferably 0.07 mm.
  • this requirement should be in a New furniture or a reground set in the unused condition available his.
  • the set shown in FIGS. 4 and 5 has an angle ⁇ of 0 Degree on, so that actually no relief is present.
  • the check marks are through Formed pieces of wire.
  • the check mark by means of a sawtooth wire as a whole emulate as all-steel set.
