An apparatus and method for depositing synthetic fibers to form a non-woven web includes guiding the synthetic fibers by a blowing stream through a drawing unit for depositing on a deposit belt. Multiple guidance elements are arranged inside the guidance distance between a blast opening of the drawing unit and the deposit belt, and form a guidance channel above the deposit belt. The guidance elements form a channel opening at a distance from the blast opening of the drawing unit. In order to achieve constant strength in the deposition of the fiber strands, the distance between the outlet of the drawing unit and the channel opening of the guidance channel is larger than half the guidance distance, and the guidance width of an open space formed between the outlet of the drawing unit and the channel opening of the guidance channel is larger than the guidance channel.

A device for melt extrusion spinning and cooling of a filament bundle comprises a spinning device with an annular spinning jet for extruding the filament bundle as well as a cooling device arranged below the spinning device. The cooling device comprises a holding device and a blowing chamber connected to the holding device. The blowing chamber is held in an operating position substantially centrally to the spinning jet in contact between the spinning device and the holding device. The blowing chamber can be axially displaced relative to the holding device between the operating position and a replacement position.
