  • the fastening means consists of at least one clamping element, which has holding means for fixed and positioned attachment to the spinning machine and is provided with a receiving slot that is open on one side and has a holding section with which a holding element attached to the carrier can form a positive clamping connection.
  • the fastening means or the clamping element is fastened to the spinning machine in a defined and predetermined position and is therefore precisely coordinated with the position of the respective drafting unit.
  • the carrier Via the receiving slot, which is open on one side, the carrier can be transferred into a fixed position via a holding element attached to the carrier, in which the holding element assumes a positive clamping connection with a holding section in the area of the receiving slot.
  • suction drums In the working position of the compaction module, suction drums rest on the circumference of the driven output rollers of the drafting unit, with the fiber material to be compacted being located and clamped between the suction drums and the output rollers.
  • the suction drums In order to obtain the desired contact force of the suction drums on the output roller, the suction drums are pressed onto the output roller with a leaf spring on a pressure arm.
  • the compression module After releasing the pressure arm and moving it to an upper position, the compression module is pivoted into a lower position by its own weight. In order to be able to start the spinning process again, the compression module must be lifted manually and brought into operative connection with the leaf spring of the pressure arm.
  • the object of the present invention is to create a compaction device with which a suction tube can be securely attached to the spinning machine and replaced, while still allowing uniform pressure on a roller of a drafting system and the drafting system can be opened and closed quickly and easily.

  • the spring device causes the suction tube to be pressed against gravity towards the stationary part of the drafting system.
  • the suction tube is pushed back into the spinning position. Due to the bearing, which is designed as a rotatable and/or tiltable floating bearing, the suction tube is able to lie precisely on the roller of the drafting system assigned to it.

The compression device 20, on the other hand, is removed from the pin 43 via the quick-release fastener, here by the clamping device using the receptacle 44. The compression device 20 can thus be replaced or cleaned. In order to be able to detach the compression device 20 from the machine, it is advantageous if the first part of the suction pipe 24 can be detached from the second part of the suction pipe 30.
