Apparatus on a bench of drawing for strips of textile fibers, in which the rollers superiors of the system of drawing are charges and soulages of the load

摘要

In an apparatus on a drawing frame for strips of textile fibers, with charging of the upper rollers of successive pairs of rollers, with an upper roller and a lower roller, in which, during the operation, the upper rollers are pressed against the lower rollers by the presser members loaded in the arms of the pressing; when the operation is suspended, the bearings of the upper rollers are relieved of load by the arms of the pressing, during an interruption of the continuous operation, the exit roller is effective in relieving the load of such a way that it does not exert any pressure, or only a slight pressure on the strips of fibres.pour avoid or reduce the formation of loops, the elastically loaded which raise the bearings of the upper rollers, after having been effective in relieving the jacks of the load are associated with the bearings of an upper roller.
