magnus rolls and magnus rolling drum

摘要

The magnus role a known manner, when – alone is used by diversion of a wind coming from the front a wind or of a wind (in the case of mounting on a vehicle) or the group consisting of two assembled in such a wind flows in their reactive resultant dahs not changed, a laterally ausscherende movement results, as has been exactly but rather a movement in the opposite direction of the thread coming from the front, whereby, however, due to the front partial cover the yield is initially lower than previously the force of the lateral coupled.When applying several magnus roles on a roll (: platen roller) we have an appropriate variation of covering and wind-diversion segments for the individual rollers of the rotating roll, the of the rollers is being cranked, in which in each case for the currently wind coming from the front half, in addition, the air stream is directed as a consequence of the rotation, it must be taken into consideration so dahs an addition of the two winch results, on the carrying rail-removing device 4, by means of covers, and by means of guide plates must be rotated further change in or reacts. This is realized by means of automatic control depending on the position of the rollers. Since, on the respective rear side of the twisted roller, the rollers move otherwise directed, we have, at this location, the (twisting) air stream of, for example, obliquely above, – on the front half of the roller – in the case of the same country wind – a (twisting) from below at an oblique angle of relative wind. demgemähs, the supply lines / detours and the opening parts that are changed or the rear, in the second half of the roller, only be adjusted to wind. The country wind, on the rear half of the total roll be prevented by lateral shield at each roller. Or, if required, by opening of a possibly only a part of the upper guide plate from above at an angle (relative wind, coming from the rotation of the roll) can also be used resulting.By use of the in the case of flows on the laminar half resulting inserting the in the brown''s movement of the molecules by means of a stored flow induced alignment of the same is no longer irregularly according to all sides, but upwardly in the direction of flow, so as to extend a good addition of suction in addition, the resultant of the rollers, which is amplified, thus also the rotation of the roll is accelerated.
