Abstract

The invention relates to a drafting system, particularly a high-capacity drafting system for fabricating staple fibers. In order to keep clean and prevent unwanted linters, filler pieces (17, 18) are provided preferably between all upper and lower rollers (3a to 6a; 3b to 6b), these filler pieces forming a conveying channel (17a, 18a) the shields the fibrous material (2). In addition, a flow channel (10, 11) is effectively assigned to the upper and lower rollers (3a to 6a; 3b to 6b), and an air flow, which is parallel to the fibrous material (2) and preferably directed counter to the direction of conveyance (1) of the fibrous material (2) is led through the flow channel in order to lead away a somewhat resulting fiber/air mixture.
