- the invention relates to a system for the continuous production of a spunbonded web of aerodynamically stretched filaments made of thermoplastic material, with a spinnerette donating the filaments, below the spinnerette a continuously movable Ablegesiebband is arranged, on which the filaments can be stored for spunbond and wherein the Ablegesiebband a Suction device is provided for sucking air through the Ablegesiebband.
- the spinnerette has spinneret holes from which the filaments of thermoplastic material can emerge. It is within the scope of the invention that the filaments are first passed through a cooling chamber into which process air for cooling the filaments can be inserted from an air feed booth. Furthermore, the filaments pass expediently into a drawing unit with a draw-down channel, which is followed by a laying unit, which preferably consists of at least one diffuser. 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
- spunbonded nonwovens are produced whose properties do not meet all requirements.
- the spunbonded nonwovens produced with the known system often exhibit inhomogeneities with respect to their filament density and mesh size. Such inhomogeneities cause undesirable irregularities, in particular with regard to the nonwoven strength, the nonwoven elongation and the permeability of the nonwoven.
- the known system is in need of improvement for this reason.
- the invention is the technical problem of specifying a system of the type mentioned above, with the most uniform spunbonded filing and the most uniform arrangement of the filaments can be achieved in the filing.
