Abstract (en)

[origin: WO2008025767A1] The invention relates to a process and apparatus for extrusion of synthetic fibres to produce a fibrous nonwoven web wherein a plurality of spinning means are provided to extrude a multiplicity of fibrous strands in a plurality of fibre groups. The spinning means are connected to one or more sources of polymer melt. To collect and lay down the fibrous strands, a moveable lay-down means is provided, so that the fibrous strands can be continuously collected and moved. To achieve very high manufacturing capacity utilization coupled with flexible use, the invention provides that one of the spinning means is guided from an operating position into a quiescent position independently of any adjacent spinning means, by a horizontal movement essentially transversely to the transport direction of the lay-down means. In the quiescent position, retrofitting and/or maintenance work can be carried out on the spinning means.
