METHOD FOR OPERATING A DRAW FRAME AND A DRAW FRAME FOR DRAWING A SLIVER

摘要

The invention relates to a method for operating a draw frame (1), in particular for starting and/or stopping a draw frame (1), for example, for replacing a barrel and/or for penetrating a sliver intoa sliver channel later. The method guides a sliver (2) to pass through drafting device rollers (4, 5, 6) of a drafting device (3); the drafting device draws the sliver (2). The method makes a thin section (7) generated in the sliver (2) so that the sliver (2) can be separated at the thin section (7). According to the invention, the thin section (7) of the sliver (2) is generated in a stop phase and/or start phase of the draw frame (1). The invention also provides a draw frame used for drawing a sliver (2). The draw frame comprises a controller which is used for at least controlling the drafting device rollers (4, 5, 6) of the drafting device (3). The controller can be arranged for implementing the method.
