Definitions

  • the present invention relates to an improvement of a fiber combing and feeding device for a rotary spinning chamber into which fibers are sucked and deposited on an annular collecting surface where a yarn is formed.
  • a rotary combing roller combs fibers out of a sliver, and the fibers are carried by the combining roller into a suction channel communicating with the inlet of the rotary spinning chamber.
  • the combing roller is located in a cylindrical cavity of a body, and forms a gap with the same, except where a peripheral portion of the combing roller is located in the suction channel. Between the outlet portion of the suction channel and one end of the gap, a sharp edge it provided for guiding the fibers into the gap.
  • Another object of the invention is to blow air into the region of the feeding device where accumulations of fibers usually take place so that gathering fibers are blown into the suction channel before a substantial number can accumulate.
  • Another object of the invention is to use the air pressure produced by the rotary spinning chamber for producing pressure air used for preventing accumulations of fibers in the feeding device of the spinning chamber.
  • the present invention relates to a fiber feeding device for a rotary spinning chamber.
  • a body has a suction channel with an outlet portion for guiding air in one direction into the spinning chamber, and a rotary combing means for combining fibers out of a sliver and being disposed so that a peripheral portion thereof is located upstream of the outlet portion in the region of the suction channel so that fibers are drawn by suction from the peripheral portion into the spinning chamber.
  • clearing means are provided for blowing pressure air at the peripheral portion so that accumulations of fibers are blown into the suction channel and are sucked through the outlet portion of the same into the spinning chamber.
  • a diffuser casing surroundingthe spinning chamber and receiving pressure air from the same is connected by a conduit with a pressure channel opening at the end of the peripheral portion leading in the direction of rotation of the same, and extending in substantially tangential direction.
  • a sharp edge is disposed between the pressure channel and the outlet portion of the suction channel and forms the end of the part-circular gap surrounding a combing roller.
  • a rotary spinning chamber 6 of known construction has a shaft 6a mounted in a bearing and driven to rotate the spinning chamber about its axis.
  • the spinning chamber has a pair of frusto-conical walls forming a circular collecting surface 7 in the region of the greatest diameter of the spinning chamber.
  • Air escape openings 8 are provided through which air is outwardly discharged due to the action of the centrifugal force.
  • the air is under pressure in the diffuser casing 12. which surrounds the portion of the spinning chamber having escape openings 8.
  • the other axial end of the spinning chamber has a wide opening into which a portion 1a,. and a boss 1b of a body 1 project.
  • Body 1 has a cylindrical cavity in which a rotary combing roller 3 is located which forms a gap 3a in the cavity.
  • a feeding roller 2 is located in an adjacent communicating cylindrical cavity and transports a sliver 18 toward the gap 3a where the sliver is engaged by the teeth or needles on the periphery of the combing roller, and divided into fibers which are oriented in circumferential direction of combing roller 3 which transports the fibers in the direction of the arrow at a speed V
  • Combing roller 3 is disposed so that a peripheral portion 4 thereof projects slightly into a suction channel 5 which extends substantially in tangential direction of the trailing end 4a of the peripheral portion 4 whose leading end 4b is located in the region of a sharp straight edge 9 provided at the end of the part-circular gap 3a.
  • a pressure channel 1 1 passes through body 1 and opens adjacent edge 9 into gap 3a.
  • a conduit means 12a connects diffuser casing 12 through a throttling valve 29 with pressure channel 11 so that pressure air is blown at a speed V in the direction of the arrow into the end of gap 3 between edge 9 and the leading end 4b of the peripheral portion 4 of combing roller 3.
  • Pressure channel 11 extends in substantially tangential direction to the leading end 4b of the peripheral portion 4.
  • a withdrawing channel 13 extends coaxially with the axis of rotation of spinning chamber 6 through body 1.
  • the yarn 14 spun of the fibers collected on collecting surface 7 is guided through withdrawing channel 13 to a pair of transporting rollers 15 which transport the spun yarn to winding means 16 by which a bobbin 17 is formed.
  • a fiber feeding device for a rotary spinning chamber having a suction channel with an outlet portion for guiding air in one direction into said spinning chamher, and a rotary combing means for combing fibers out of a sliver and being disposed so that a peripheral portion thereof is located upstream of said outlet portion in the region of said suction channel so that fibers are drawn by suction from said peripheral portion through said outlet portion into said spinning chamber, in combination with an improvement comprising clearing means for blowing pressure air at said peripheral portion so that fibers escaping from said suction channel are blown into said suction channel and are sucked through said outlet portion into said spinning chamber whereby fiber accumulations are prevented.
  • said clearing means include a pressure channel opening at said peripheral portion, and air supply means for supplying pressure :air to said pressure channel.
  • said air supply means comprises a difiuser casing receiving pressure air from said spinning chamber, and conduit means connecting said diffuser casing with said pressure channel.
  • said combing means is a combing roller; wherein said peripheral portion has ends leading and trailing, respectively, in the direction of rotation of said combing roller; wherein said suction channel extends in substantially tangential direction of said trailing end; and wherein said pressure channel extends in substantially tangential direction of said leading end.
  • said clearing means comprise a diffuser casing receiving pressure air from said spinning chamber, a pressure channel opening at said peripheral portion, and conduit means connecting said diffuser casing with said pressure channel.
