Abstract
An apparatus for determining a point of regulation in a drafting unit includes a sensor for generating signals as a function of change in a quality-representing magnitude of the fiber material running through the drafting unit; a control device receiving the signals for varying a draft of the fiber material by the drafting unit; and an arrangement for continuously determining, during operation, optimal points of regulation based on the signals.
Claims17
A method of determining a point of regulation in a drafting unit, comprising the following steps:
- (a) passing fiber material through the drafting unit;
- (b) generating signals as a function of change in a quality-representing magnitude of the running fiber material;
- (c) applying said signals to a control device for varying a draft of the fiber material by the drafting unit;
- and
- (d) continuously determining during operation optimal points of regulation based on said signals.
