Definitions

  • DE 199 64 595 B4 shows a pneumatic compression device in which the output lower roller of the drafting system is followed by a suctioned, stationary hollow profile, over which a perforated conveyor belt runs. Above the hollow profile, a pinch roller is provided, which is driven by a gear from the output top roller of the drafting system and which presses the conveyor belt from above against the stationary hollow profile and thereby drives it.
  • the pinch roller and thus the conveyor belt must always run for technological reasons in a certain ratio to the peripheral speed of the driven output lower roller. If the covers of the drafting rollers are reground due to wear, the pinch roller is also correspondingly nachzuschleifen, otherwise the ratio would be changed by the diameter reduction. The maintenance of this compacting device is complicated due to this structure.
  • compaction devices is disposed between an output roller pair and a delivery roller pair of the drafting system.
  • the upper rollers of the drafting system are arranged in a conventional manner on a load carrier or load arm.
