Definitions

  • the present invention relates to a combing machine for cotton, wool and the like with improved sliver forming device.
  • the invention relates to a combing machine provided with a device for forming sliver of combed material, that has a higher combed material production rate than known types of solutions.
  • US-A-5 022 122 discloses a combing machine with at least one detaching roller.
  • the aim of the present invention is to provide a combing machine for cotton and the like with an improved sliver forming device that allows to perform an accurate and optimum overlap of the cotton tufts.
  • an object of the present invention is to provide a combing machine for cotton and the like with a sliver forming device that allows to vary the overlap of the cotton tufts while the combing machine is operating, though having a reduced mechanical complexity.
  • Another object of the present invention is to provide a combing machine for cotton and the like that allows to achieve further removal of dust from the material, in addition to the dust removal performed during the combing of the head tufts.
  • Another object of the present invention is to provide a combing machine for cotton and the like with an improved sliver forming device that is highly reliable, relatively simple to provide, and at competitive costs.
  • the combing machine generally designated by the reference numeral 1
  • the combing machine comprises a combing section, which is disclosed in a copending patent application by the same Applicant, which is not described here in detail, followed by a sliver forming section 2, to which the present invention relates.
  • the combing section designated by the reference numeral 3, comprises a roller 4 for feeding tufts 5 of cotton to be combed, which are passed between two jaws 6 and 7, which are provided with at least one comb that is adapted to comb the cotton tufts 5.
  • the combed tufts in which therefore all the fibers have the same length, since fibers that are shorter than the preset length have been rejected earlier, are sent to a fixed comb 8, which combs the tails of the cotton tufts 5 and provides the combed cotton to the sliver forming section 2, which comprises at least one pair of rollers 9 and 10 through which the combed material 5 is passed continuously.
  • the combed material 5 in output from the rollers 9 and 10 is conveniently sent to a device 11 for forming the combed sliver, comprising a box-like body 12, which comprises at least one opening 13 on each side for the emission of air at negative pressure and, at the upper region of the box-like body 12, at least one, and preferably a plurality of, suction holes or notches 14, adapted to act by negative pressure, above which a mat or belt 15, conveniently made of permeable material, is arranged; said mat conveys the material that arrives from the rollers 9 and 10.
  • the mat 15 is operated by actuation means 19.
  • the box-like body 12 can be easily removed/positioned, since it is pivoted in a point 17 and kept under traction by means of a spring 18, so that it is in contact with the actuation means 19.
  • suction is used; said suction is generated by means of the holes 14, which allow to keep the belt, and therefore the combed material 5 arranged thereon, in contact with the box-like body 12 of the sliver forming device.
  • the rollers 16 are actually two output rollers 16, which unload the combed material 5 formed into a sliver onto a collection surface, not shown.
  • the material 5 deposited on the belt or mat 15, which is preferably of the permeable type, is formed into a sliver by using the mat that provides the overlap of the tufts of combed material, utilizing the ratio between the length of the material 5 that arrives from the rollers 9 and 10 and the advancement speed of the mat 15.
  • the holes 14 are used to provide a negative pressure and thus keep the material 5 in contact with the mat 15.
  • the number, position and cross-section of the holes 14 are extremely important factors for the optimum overlap of the tufts 5 and accordingly for the quality of the sliver of resulting combed material.
  • the rate of advancement of the material 5 determines its degree of overlap.
  • the advantages that can be achieved by the sliver forming section according to the present invention are the fact that the various lever systems and/or differential devices typical of the background art are eliminated completely. Moreover, the overlap of the material is considerably more precise, and it is possible to vary the overlap while the combing machine is operating, varying for example the conveyance rate of the combed material 5.
  • the materials used may be any according to requirements and to the state of the art.
