Definitions

  • the invention relates to a roller for processing fiber masses in the textile industry, with sawtooth wire fastened to the roller circumference in thread-like grooves, which fills the grooves with its lower, approximately rectangular foot region in cross section and is held by caulking.
  • the object of the invention is to provide a fastening method for sawtooth wires in rolls of the type mentioned, which makes it possible to use very strong materials such as steel for the roll. It is also an object of the invention to provide a hollow cylinder with a particularly small wall thickness.
  • the roller can be made in particular of steel. It is particularly advantageous if the foot region protruding beyond the groove is deformed by caulking.
  • the foot can have a particularly low height, in particular 1 mm or less.
  • the sawtooth wire be made of steel and have a hardness of 160 to 250 HV in the base, in particular approximately 180 HV, and a hardness of 800-920 HV in the tooth tips.
  • the roller has the shape of a hollow cylinder which can be releasably attached to a cylindrical base body.
  • a particularly small wall thickness of the hollow cylinder is achieved if the hollow cylinder is made of steel.
  • the steel have a strength of at least 300 N / mm2, in particular at least 400 N / mm2.
  • the wall thickness of the hollow cylinder can thus be 1.0 to 3 mm. It is also advantageous if the groove depth is 0.2 to 0.7 mm, preferably 0.5 mm.
  • a roller in the form of a hollow cylinder ring, sleeve made of steel has a roller shell 1 of 1 to 3 mm wall thickness, in its peripheral surface thread-like or helical grooves or grooves 2 of 0.2-0.7 preferably about 0.5 mm depth are introduced at regular intervals.
  • a sawtooth wire 3 is inserted into these grooves 2 of rectangular cross section, the lower foot region 4 of which corresponds approximately to the cross section of the groove 2, the upper side 6 of the foot region 4 projecting somewhat beyond the webs 8 between the grooves.
  • the teeth 5 are formed eccentrically on the foot area 4, so that in addition to the teeth 5, an upper surface 6 on the foot area 4 remains free, which is deformed by a caulking roller 7, so that the foot area 4 is then clamped in the groove 2, see the left Area in the drawing.
  • the caulking roller 7 can not only deform the surface 6, but also an adjacent area of the webs 8 of the roll shell arranged between the grooves 2.
  • the inside diameter of the hollow cylinder is preferably 54 mm and the outside diameter is 56 to 60 mm.
  • the steel of the hollow cylinder has a strength of at least 300 N / mm2 (especially free cutting steel) and the steel of the saw tooth wire has hardness values in the base between 160 and 180 HV or 170 and 190 HV or between 180 and 200 HV or between 190 and 210 HV up to 250 HV. Values around 180 HV are favorable.
  • the hollow cylinder is preferably made of steel, in particular cast steel, cast bronze or brass.
