Definitions

  • the invention relates to a double-wire twisting machine with a plurality of twisting spindles arranged next to one another and having a bobbin and with an automatic maintenance machine that can be produced on the individual twisting spindles.
  • a double wire twisting machine is e.g. known from DE-A-3 824 998.
  • Cross-wound bobbins with a long thread length are produced on double-wire twisting machines.
  • the operating times for a full untwisted bobbin are between 4 and 44 hours and more.
  • Double wire twisting machine associated work processes inevitable dust and sometimes also contamination of the double wire twisting machine. It is therefore common to equip such and other machines, such as spinning machines, with traveling blowers, which come past every working or twisting point at certain intervals and keep certain areas of the machine free of excessive dust or contamination by blowing or suction flows. Although these measures are helpful, they are usually inadequate in the case of double-wire twisting spindles, because certain thread areas cannot be reached due to the thread balloon resulting from the double-wire twisting. This is particularly true for the spindle area and especially for the coil pot and the balloon limiter, but also for the spindle rotor itself.
