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.
Claims5
A method of depositing a filament tow into a stationary can, comprising the steps of:
- conveying the filament tow in a conveyance direction and depositing the filament tow into the stationary can by a driven conveyance means;
- and
- guiding the filament tow such that the deposition position of the filament tow in the stationary can changes constantly;
- wherein for guiding the filament tow, the conveyance means performs a first oscillating motion transverse to the conveyance direction and a superimposed second oscillating motion transverse to the conveyance direction, the direction of the first oscillating motion being oriented transverse to the direction of the second oscillating motion;
- and
- wherein the filament tow is guided by the conveyance means formed by two driven reels which cooperate with one another for conveying the filament tow.
