Abstract

A bobbin exchange apparatus on a ring spinning or a ring twisting machine contains a transporting belt extending substantially horizontally in the longitudinal direction of the machine. The transporting belt is provided with bobbin holders and, viewed relative to the machine, is inclined downward towards the front. According to the invention, there are provided supporting means extending in the longitudinal direction of the machine. These supporting means are contacted by the front side of the empty bobbin tubes placed onto the transporting belt. The invention permits a considerable space saving to be achieved in such a manner that, in comparison to known machines, more space is available for the spindle bearings or bolsters and there can be used a spindle rail which fulfils the requirements of sufficient stability. Furthermore, the invention allows an improved spinning geometry to be chosen.
