Definitions

  • the present invention relates to twisting machines for twisting pairs or quads for telephone cables.
  • the main feature of the present invention is that the twisting die is rotated alternately left and right relatively to the pair or quad.
  • the pair or quad is thereby alternately subjected to the left and right rotation of the die and due to uneven tangential friction of the different conductors, the imbalances will be alternately plus and minus. This results in lower imbalances such as side to side, phantom to side, side to earth and phantom to earth.
  • FIG. 1 schematically shows a star quad twisting machine with rotating pay-off and non-rotation take-up
  • FIG. 2 schematically shows a star quad twisting machine with rotation take-up and non-rotation pay-oil.
  • FIG. 1 indicates that the pay-off arrangement including the lay-plate 2 is rotated at the rotational speed W
  • the quad is therefore also rotated at the rotational speed W and the twisting die should therefore be rotated alternately left and right relative to this rotational speed.
  • the rotational speed of the twisting die W should therefore alternately be W W +W and W W -W.,.
  • the values W and W may e.g., be chosen so that both values are equal to W in that case the twisting die is alternately rotated at twice the speed of and in the same direction as the pay-off arrangement and alternately is not rotated.
  • Any suitable known driving means 6 may be used to rotate die 3. Similar driving means may be used to rotate the pay-off arrangement including the lay plate 2.
  • FIG. 2 it is indicated that the take-up arrangement is rotated at the rotational speed W
  • the quad and lay plate 2 are not rotated, i.e. the four conductors 1 always enter the twisting die at the same position and are merely screwed through the die, so that the twisting die in this case should be rotatably alternately left and right relative to zero speed.
  • the twisting die would then be alternately rotated at the same speed and in the same direction as the take-up arrangement and alternately be rotated at the same speed but in the opposite direction as the take-up arrangement.
  • the invention may also be used in connection with twisting machines comprising rotating take-up as well as rotating pay-off.
  • the time period including one right and one left rotation period may also be varied.
  • a twisting machine for twisting cable conductor pairs and quads comprising a lay plate member supporting and guiding said conductors, a twisting die, and a take-up bobbin member, one of said members being stationary and the other being rotatable to rotary said conductors, and means for rotating the twisting die left and right alternately relative to the rotation of the conductors thereby reducing the capacitance and inductance imbalances imparted to the conductors.
  • a twisting machine including means for rotating said lay plate with respect to a nonrotating take-up bobbin and means alternately rotating the twisting die at twice the speed of and in the same direction as the lay plate and alternately not rotating said die.
  • a twisting machine comprising means rotating said take-up bobbin with respect to a 2,162,131 6/1939 So1;1e1 vi11e 5 7 -58 36 XR non-rotating lay plate end nieans alteinatelg rotating the V 2,238,496 4/1941 McDonald 5715 XR twisting die at the same speed and in the same direction 2,412,196 12/1946 Ashbaugh et a1 5759 'as the take-up bobbin and alternately rotating the die at 2,924,930 2/1960 Crosby et a].
