Abstract
The present invention provides a process and device for the reduction of energy consumption in operating spinning elements in driving spinning rotors of open-spinning machines or the spindle drive of ring spinning machine or the roving frame. It is the object of the invention to constantly keep energy consumption in the operation of spinning element at a minimum. Contact pressure between each spinning element and the indirect driving device is adjusted as a function of the momentary difference between the rotational speed of the spinning element and of its driving device in stationary operation while rotational speeds only nominally change, so that the slippage between indirect driving device and spinning element remains constant in time.

A process for controlling driving of textile machine spinning elements during all operations in which they are driven through direct contact with a driven device, said process reducing the energy consumption required for operation of the spinning elements, said process comprising the steps of:
- determining the actual rotational speed difference between a spinning element and the driven device;
- and
- varying the contact pressure between the spinning element and driven device as a function of the actual difference of the rotational speeds thereof.
A textile machine having a spinning element driving control device for controlling contact pressure between a spinning element and an associated driven device through essentially all phases of operation of said spinning element, said device significantly reducing the energy consumption required for operation of the spinning element, said spinning element driving control device further comprising:
- a contact pressure adjusting device, said adjusting device operably configured to maintain the contact pressure between said spinning element and said driven device;
- and
- control means operably configured with said adjusting device for varying the contact pressure between said spinning element and said associated driven device as a function of the actual rotational speed difference between the spinning element and the driven device.
A textile machine, said machine comprising:
- a plurality of spinning elements;
- a driven device operably configured to contact said spinning elements for rotating said spinning elements;
- adjusting means for adjusting the contact pressure between said spinning elements and said driven device;
- control means operably configured with said adjusting device for varying the contact pressure between said spinning elements and said associated driven device as a function of the actual rotational speed difference between the spinning elements and the driven device.
