Machine frame for a ring spinning or ring twisting machine

A machine frame for a ring spinning machine having on each side stationary spindle rails, ring rails that can be moved up and down and yarn guide rails that can also be moved up and down, the machine frame comprising:

• a plurality of vertical supporting columns that extend to a floor surface and support the spindle rails of the machine, and which are arranged on each side of the machine opposite one another in pairs,
• intermediate pieces for connecting the vertical columns with one another, said intermediate pieces holding the spindle rails of the machine and extending transversely to the longitudinal direction of the machine.
• ring rail holders for holding the ring rails of the machine,
• a roller guide having rollers offset with respect to height and riding on the vertical columns, the roller guide being coupled to the ring rail holders to provide guided vertical movement of the ring rail holders on the vertical columns, and
• yarn guide rail holders, guidingly vertically movably coupled to the vertical columns, for holding the yarn guide rails of the machine, wherein the yarn guide rail holders and the ring rail holders are movable on the vertical columns independently of one another,
• and wherein the intermediate pieces have recesses substantially adjacent said vertical columns at the upper surface of said intermediate pieces for accommodating the ring rail holders when said ring rail holders are moved downward to the spindle rails of the machine.
