Patent ID: 7798795

Claim:
An apparatus for depositing synthetic filaments on an advancing deposit belt to form a non-woven web, comprising a drawing unit arranged below a filament spinneret and comprising a guide channel having a slot-shaped filament inlet and a slot-shaped filament outlet, a plurality of fluid inlets communicating with the guide channel and which are connected to a fluid source, and so that the fluid and entrained filaments leave the guide channel through the filament outlet as a filament stream, a deposit belt arranged below the filament outlet with a free distance (A) between the filament outlet and the deposit belt, with the deposit belt being driven for movement in a direction transverse to the filament outlet, and deflecting means for deflecting the filament stream leaving the filament outlet unilaterally in the advancing direction of the deposit belt in such a manner that the filaments impact upon the deposit belt at an angle of <90° due to a Coanda effect, wherein the deflecting means comprises a shaped body that extends laterally to the filaments above the deposit belt on the side of the deposit belt upon which the filaments impact and the deflecting means extends substantially over the free distance (A) between the filament outlet and the deposit belt, wherein the deflecting means is positioned relative to the belt such that the filaments impact the belt proximate the tip of the deflecting means, and wherein the position of the deflecting means is adjustable such that its distance and height can be changed relative to the filament stream.
