Abstract
The upward twisting machine, in particular double twisting machine, comprises for each twisting point a creel (3) and an associated take-up cylinder (6) as well as a carrying arm which is pivotable about a pivot axis arranged on the vertical longitudinal centre plane (M) and extending parallel thereto, which carries the creel (3). The pivot axis (5) of the carrying arm (4) is provided in the region below the conveyor belt (2). The pivot radius (R) of the bobbin axis (S) of a take-up bobbin (7) held in the creel (3) is dimensioned relative to the pivot axis (5) in such a way that the line of contact (B) between the bobbin winding and the take-up cylinder (6) is always located on the side facing towards the vertical longitudinal center plane (M), of a vertical plane (V) passing through the axis (A) of the take-up cylinder (6). Furthermore, a cover plate (9) sloping downwards the conveyor belt (2) is provided between the take-up cylinder (6) and the conveyor belt (2 ).
