Abstract

A device for gripping the underwinding yarn for a ring spinning frame comprises a collar (14) fixed to the spindle (2), a sleeve (24) able to slide axially and a bar (40) supported by a pair of pneumatic actuators.
The support axis (Z-Z) of the bar (40), defined by the points where the bar is supported by the actuators (70a,70b), intersects the active portions (42) of the bar (40) that engage with the sleeve (24) in order to stiffen the bar (40), and simultaneously open the sleeves (24) of the spindles of the spinning frame.
The engagement portions (70a,70b) of the bar (40) that engage with the actuators are longitudinally separated from its active portions (42) in order to make the spinning frame compact and make the presence of the actuators compatible with the wharves (10) of the spindles (2) and with the drive means by which they are turned.
The bar (40) moves vertically in order to engage/disengage the spindle (2).
