Abstract

A ring-spinning or ring-twisting machine with a ring rail having rings and travelers for each spinning or twisting spindle. The horizontal ring rail is displaceable on rigid vertical rods, the lower ends of which are connected to vertical stretches of flexible traction elements which lie substantially in the vertical plane of the weight axis of the ring rail.

Claims

1. A textile machine comprising:

a machine frame;

a spindle rail on said machine frame having a multiplicity of spindle stations each provided with a respective spindle;

a horizontal ring rail displaceable vertically on said machine frame and having respective rings surrounding said spindles and adapted to receive respective travelers traversed by respective yarns to be wound on bobbins of the respective spindles, said ring rail having a longitudinal axis containing the center of gravity of the ring rail and lying in a plane of said center of gravity;

vertical guides on said machine frame below said ring rail;

rigid vertically displaceable drive elements guided in said vertical guides and connected to said ring rail for lifting and lowering said ring rail, said drive elements extending downwardly from said ring rail;

a bracket extending transversely from one of said drive elements toward said plane and affixed to said one of said drive elements below said ring rail; and

at least one flexible traction member upon which a pull is exerted to lift said ring rail, said traction member extending vertically parallel to said plane.

2. The textile machine defined in claim 1, further comprising a bobbin and core sleeve transporter extending along said frame and disposed outwardly from said plane in a direction away from a longitudinal central axis of the machine.

4. The textile machine defined in claim 1, claim 2 or claim 3 wherein said traction member has a downwardly extending end connected to said bracket.

5. The textile machine defined in claim 4 wherein said one of said drive elements is a rigid vertical rod, said bracket being connected to said rod at a bottom thereof.

6. The textile machine defined in claim 5, further comprising a roller on said frame, said traction member passing over said roller.

7. The textile machine defined in claim 6 wherein said traction member also lies in a plane perpendicular to said axis and is wound on another roller for applying said pull to said traction member.

8. The textile machine defined in claim 1 or claim 3 wherein said machine is a ring spinning machine.

9. The textile machine defined in claim 1 or claim 3 wherein said machine is a ring twisting machine.

3. A textile machine comprising:

a machine frame;

a spindle rail on said machine frame having a multiplicity of spindle stations each provided with a respective spindle;

a horizontal ring rail displaceable vertically on said machine frame and having respective rings surrounding said spindles and adapted to receive respective travelers traversed by respective yarns to be wound on bobbins of the respective spindles, said ring rail having a longitudinal axis containing the center of gravity of the ring rail and lying in a vertical plane of the center of gravity;

vertical guides on said machine frame below said ring rail;

rigid vertically displaceable drive elements guided in said vertical guides and connected to said ring rail for lifting and lowering said ring rail, said drive elements extending downwardly from said ring rail;

a bracket extending transversely from one of said drive elements toward said plane and affixed to said one of said drive elements below said ring rail; and

at least one flexible traction member upon which a pull is exerted to lift said ring rail, said traction member having a vertical stretch connected to said bracket and parallel to said vertical plane of said axis; and

a bobbin and core sleeve transporter extending along said frame and disposed in said plane, said traction member lying inwardly of said plane toward a longitudinal central axis of the machine.
