Abstract
The invention relates to a method and to a device for depositing a filament tow in a stationary can. To this end, the filament tow is conveyed to the can by a conveyance means, and for deposition into the can the filament tow is guided in such a way that the feed position of the filament tow in the can constantly changes. To allow the filament tow to be deposited with a high filling density, for deposition into the can the filament tow is guided according to the invention by oscillating motions of the conveyance means during conveying which are transverse to the conveyance direction. In this manner, undesired reactions on the filament tow are advantageously avoided during deposition.
