Abstract
A winding station in a traverse winding frame for winding thread on a package comprises a belt drive for rotating a cheese or bobbin via a driving roller and a grooved drum for thread laying. The grooved drum drive has a continuously variable gear, whose speed is continuously variable by an adjusting linkage. The speed of the cheese and the grooved drum is measured by two tachometers and supplied as a corresponding signal to a computer, in which the actual value calculated from the two signals is compared with a desired value stored in the computer and a correction signal is then fed to a control element for adjusting the adjusting linkage. Thus, the cheese can be wound with a thread winding, which combines the advantages of a random winding with a constant pitch angle and a precision winding with a substantially constant turns ratio during partial windings, without suffering from their disadvantages.
