Definitions

  • the conventional spinning machine with flyer is composed of: a plurality of flyers mounted on a plurality of spindles, which are arranged in a pair of parallel rows; a bobbin rail movable upward and downward, so as to wind a roving onto a bobbin; a roller beam, on which a drafting roller assembly is mounted, arranged above and behind the top of the flyers; a plurality of walls or supports, which support said roller beam, are arranged withinthe area in back of said pair of parallel rows of flyers, and; a creel for feeding slivers from the sliver cams or similar package.
  • This spinning machine includes a plurality of flyers of the closed leg type, i.e., the bottom and the top of both legs are connected to the bottom flange and the top flange respectively, said top and bottom flanges are mounted on the flyer rail and bobbin rail respectively. Furthermore, movement of the bobbin rail upward and downward is dispensed with, and a new type of telescopic spindle is provided.
  • a twisting and winding drive mechanism is arranged within the gearing end frame which is situated at the end area of a pair of parallel rows of flyers and spindles. However, the arrangement of roller beam, supports and creel remain unchanged.
  • the principal object of the present invention is to provide a spinning machine having none of the above mentioned drawbacks of the doffing and donning operation, by providing a front alley and a back alley along the row of spindles, and making a similar arrangement of pillars, flyers and spindles on both sides of the frame, so that the doffing and donning operation from either 2 the front or back alleys can be accomplished with the same ease as in the case of a single row of flyers and spindles.
  • flyers of the spinning machine of the present invention are arranged so that the front and back rows are angularly displaced 180 from each other to minimize vibration, the above drawbacks in the doffing and donning operation are eliminated. That is, with the present invention, exactly the same relationships exists between the pressures and each spinner standing in the front or back alley and, therefore, rotation of the flyer is unnecessary. This condition is optimum for the doffing and donning operation of the spinning frame.
  • the spinning machine of the present invention provides a pillar with a round, smooth surface, instead of said walls or supports. Furthermore, the twisting and winding drive apparatus are arranged within the gearing end, which is arranged at the end of flyer rows, so there is no chance of accumulation of flies on these apparatus. In the present case, such flies will be conveyed to the floor which is outside the frame. As operation of flies tends to increase with high speed running and large package systems, the spinning machine of the present invention is very suitable for higher speed running and larger packages.
  • Another object of the present invention is to provide a machine which is more suitable for large packages.
  • the driving mechanism for the flyer is generally provided with a direct gear train.
  • the driving mechanism of the present invention is a belt driving arrangement. This means that there is no limitation on the distance between the front and back rows of flyers in the present invention.
  • the distance between the front and back rows of flyers must in general be shorter than the distance between adjacent flyers. This means that the arrangement of the belt drive of the present invention is more suitable for a larger package.
  • An additional characteristic feature of the spinning machine of the present invention is the provision of a draft mechanism positioned at a particular symmetrical position and mounted on the flyer rail directly.
  • the draft mechanism is mounted on the main frame behind the flyer.
  • the distance between the nip point of the front roller and the top of the corresponding flyer arranged in the back row differs from that between the nip point of the front roller and the top of the corresponding flyer arranged in the front row.
  • the leading angle of spinning material from the nip point of the front roller to the flyer top in connection with the back row differs from that of the front row. Consequently, products having two different numbers of twists and thickness in accordance with the position of flyer are inevitable whether it is arranged in the back row or front row.
  • the spinning machine is provided with: a bobbin rail or support member which holds a driving mechanism for driving and lifting each spindle so as to make a package upon a bobbin held by the corresponding spindle, and; a flyer rail or support member which suspends a plurality of flyers in their rotatable condition at corresponding positions facing the respective spindles, and the flyer rail is rigidly supported by means comprising a plurality of pillars vertically secured to the bobbin rail; means for rotationally driving the flyers; a gear end, which houses a twisting and winding drive apparatus and which is situated at the end of the flyer rows, and; a draft mechanism comprising the same number of drafting elements as spindles mounted on the flyer rail.
  • the spinning machine of the present invention can eliminate all of the drawbacks which exist in the conventional and the improved spinning machines. Consequently, the spinning machine of the present invention can have the characteristics of: ease in the doffing and donning operation; freedom from the trouble generated by flies; suitability for high speed running and; finally, suitability for use with large packages.
