Definitions

  • the invention relates to a milling head of a fiber bale milling machine with a milling drum, a grate through which the teeth of the milling drum reach, and a combing roller which runs parallel to and in the same direction with it and in the milling travel direction behind it, for combing fibers out of the milling drum.
  • a milling head with the generic features is known from a brochure B 12 666104401 7/82 from Marzoli. This has a combing roller parallel to the milling drum. Both rollers rotate in the same sense, and the milling roller plucks fiber material from the bale and conveys this to a suction hood, the grate lying between the two rollers and the fiber bale. The transfer rollers convey all fibers into the Suction channel, regardless of whether it is sufficiently dissolved, ie short enough.
  • the object of the invention is to design a generic milling head so that only fibers and associations of connected fibers that do not exceed a certain length of 80 mm, for example, are conveyed through it.
  • the grate in front of the area mentioned between the milling drum and the combing roller is preferably extended upward beyond the milling plane. It is also preferred that the grate above the combing roller is extended parallel to the milling plane up to the wall of the milling head.
  • the drawing shows an embodiment of the invention.
  • a milling head 2 which can be guided through a milling machine frame 3 along a row of fiber bales 4, contains a milling drum 5 which can be driven about an axis 5a and a grate 1 which is fastened to a milling head 2 at a position 1a at one end thereof and with one part 1c rests on the fiber bale 4 in such a way that the teeth of the milling drum 5 can pluck fibers out of the bale 4 between the parallel bars of the grate 1, which fibers are then thrown by these teeth to a suction hood B.
  • the milling head 2 also has a combing roller 7 which can be driven in the same direction of rotation about its axis 7a parallel to the axis 5a of the milling roller 5 and has such a distance from the fiber bales 4 that its teeth do not engage in it.
  • the rollers 5 and 7 are so close to one another that the teeth of the combing roller 7 can free the milling roller 5 from any fibers still remaining thereon; they are preferably such that the circumferential circles of the teeth of both rollers 5 and 7 touch or slightly overlap each other.
  • the grate 1 is extended beyond the point at which it rests on the bales 4 in such a way that it passes between the axes 5a and 7a of the rollers 5 and 7 and then on the side opposite the bale 4 the combing roller 7 runs and is attached at its end at 1b to the milling head 2.
  • the milling drum 5 When the milling drum 5 rotates, its teeth pluck individual fibers as well as fibers connected to fiber associations from the fiber bale 4 and throw the individual fibers and the light and shorter fiber associations to the suction hood 6. Longer and heavier fiber associations are removed by the combing roller 7 from the milling roller and onto the Thrown surface of the bales 4 When this fiber bale site is subsequently plucked off, such dressings are generally broken up by the milling drum 5.
