Abstract
An improved ring spinning machine for making a filled bobbin of yarn, thread or the like comprises at least one ring rail which moves up and down near a plurality of spindles driven by a ring rail drive. A control for the ring rail drive in case of an unforeseen machine stoppage, is arrayed so as to cause the ring rail drive, when it would otherwise drive the ring rail in the upward direction on restart because the ring rail was moving up at the time of shut-off, to reverse so that the ring rail moves downward no later than the time of restart of the spindles, so that the ring rail moves downward after the unforeseen machine stoppage at the beginning of restart thus providing for a safer, more reliable spinning operation.
