Definitions

  • the invention relates to a flat bar for carding machines, which consists of a hollow profile formed from sheet metal, which has a clothing receiving part and a back part arranged in a T-shape.
  • Flat bars are usually made of cast iron and have a T-shaped cross section for stiffening. These flat bars are heavy and, especially in the case of oversized carding machines, bend under their own weight, which impairs the carding work. In addition, the flat drive for revolving flat cards is subject to special loads due to the high weight of the flat bars.
  • the object of the present invention is to avoid these disadvantages and to create a flat rod which can be produced easily and with high precision with low weight.
  • the object is achieved in that the clothing receiving part and the back part are made in one piece from a tubular material piece which is drawn into the predetermined profile shape.
  • the flat bar according to the invention is characterized in that the tolerances required for a good carding result are reliably achieved in a simple manner and the flat bar also maintains the shape given to it with these tolerances when it is used later. This is true even for flat bars, the length of which is longer than the normal one.
  • the flat rod is made from a seamless tube.
  • a high rigidity of the flat rod is achieved in that the back part, which is formed from two longitudinal walls, consists of a rectangular part which tapers towards the free end in a roof shape.
  • This design of the back part allows the flat bar to be kept narrower than was previously possible for reasons of rigidity, so that the number of flat bars involved in the carding work can be increased. This has a favorable effect on the carding result.
  • the height of the rectangular part and the height of the tapering part are advantageously chosen so that they are in a ratio of about 1: 1.
  • the rigidity of the flat bar is further improved in that the width of the rectangular part is about 1/2 to 3/4 of the width of the clothing receiving part.
  • a secure attachment of the clothing to the lid by means of so-called "clips" is achieved in that the clothing receiving part has inclined inwardly extending holding surfaces for clothing clips which connect the clothing receiving part to the back part. It has been shown that it is particularly favorable with regard to the load on the flat bar under its own weight and the carding work if the ratio of height to width of the flat bar is 2: 1 to 4: 1.
  • Sheet steel is preferred as the material for the hollow profile, since it has a high modulus of elasticity and its coefficient of thermal expansion corresponds to that of the carding machine. A further reduction in weight with a sufficiently high rigidity of the flat bar in the longitudinal and transverse directions is achieved in that the thickness of the sheet is 1 to 3 mm.
  • the underside of the clothing receiving part is coated with a synthetic resin.
  • the interior of the hollow profile is filled with foam to dampen vibrations and noise.
  • the drawing shows in cross section a flat rod designed as a hollow profile, which is made in one piece from a tubular material piece.
  • the tubular material piece which is preferably made of sheet steel, has been brought to the cross section shown in the drawing process.
  • the tubular material piece subjected to the drawing process is expediently a seamless tube, but a tube which has a weld seam can also be used.
  • the flat bar consists of a clothing receiving part 1 and an adjoining back part 2, which is formed from longitudinal walls 3 and 4.
  • the longitudinal walls 3 and 4 lie parallel to one another and form a rectangular part 2a, which then tapers towards the free end in a roof shape.
  • the height of the rectangular part 2a and the height of the roof-shaped part 2b are preferably in a ratio of about 1: 1.
  • the width a of the rectangular part 2a is approximately 1/2 to 3/4 of the width b of the clothing receiving part 1.
  • the sheet thickness is 1 to 3 mm, preferably 2 mm, while the ratio of height h to width b of the flat bar 1 is in the range from 2: 1 to 4: 1.
  • the profile shape shown is preferred because it gives the flat bar high stability with a small width.
  • the interior of the hollow profile is expediently foamed in order to dampen vibrations and noise.
  • the underside 5 of the clothing receiving part 1 is coated with a synthetic resin.
  • the clothing can be fastened to the clothing receiving part 1 in any manner, for example by means of the usual fastening clips (clips) or a screw connection.
  • clips fastening clips
  • the clothing receiving part 1 has holding surfaces 6 and 7 for the clips which run obliquely inwards. These holding surfaces connect the clothing receiving part 1 to the back part 2.
  • the flat bar according to the invention can be used both as a revolving lid and as a stationary carding element. When used as a revolving lid, it ensures smooth running.
