Under the laying unit, the depositing device for filing the filaments to the spunbonded web is provided, wherein part of the depositing device is the above-mentioned continuously movable Ablitissiebband. On this Ablitissiebband the filaments are deposited to spunbond.
  • the reject screen is an endless belt.
  • the filaments are sucked by means of air, which is sucked by the suction device through the wire, as it were sucked onto the Ablegesiebband and deposited there as spunbond or spunbonded web.
  • the Ablegesiebband is therefore permeable to air and the air is sucked through the Ablegesiebband to ensure a reliable storage of the spunbonded fabric.
  • a pressure roller or a pressure roller pair for the spunbonded fabric is usually arranged
