Abstract

Selective rapid stop device that at least one spindle in spinning machines and the like, such as ring twister and stretch and twist banks and equivalent textile machines, comprising plural spindles driven by groups, by means of transmission belts whose circuit materializes a closed path that includes contact and tangential arcs with at least one drive pulley and a plurality of pulleys coaxially associated with the individual spindles of the group, characterized in that it comprises, for each individual spindle, a support element that can, coaxially rotating about the axis of the respective spindle, a small idler or idler pulley being mounted on this element which normally occupies an internal position to the belt circuit and close to the corresponding spindle pulley, and means which act under the effect of a signal that sends the yarn break or other irregularity leading to non-feeding of the spindle thread or to execute the aforementioned support element execute a rotation that has the double effect of moving the associated sheave to the outside of the circuit, which results in crazily moving the transmission belt, so as to physically separate it from the pulley of the particular spindle before being stopped, and respectively to actuate a braking means that allows the rapid stop of the spindle thus separated from said belt. By a hook carried by an arm capable of oscillating and applied by an elastic means to its hooking position, because said block is in turn supported by the arm mentioned, and because the support thread presents (Machine-translation by Google Translate, not legally binding)
