Abstract
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.
