Abstract
An apparatus for braking and positioning a spinning or twisting spindle with the spindle rotor in a specified position, having a spindle brake which engages with a rotary part, preferably a wharve, of the spindle, and, separate from said brake, positioning means comprising an additional braking surface which extends over part of the periphery of a rotary part, preferably a wharve, of said spindle and up to which an additional brake member is movable. The apparatus provides a more simply constructed braking and positioning means where it is permissible for the spindle to be stopped within a certain angular range about a prescribed central position. In the illustrated embodiment, a spindle brake proper comprises shoe means 7 engageable with an inside periphery of a skirt 5 of wharve 4, and there is provided positioning means comprising an additional braking surface 9 which preferably extends over an angle from 15.degree. to 30.degree. and which is engageable by an additional brake shoe 12. Movement of a toggle device 14, 15 downwards to a substantially straight position applied the spindle brake proper to stop the spindle rotor, and also causes, through fluid operated means, inward m…
