Method and apparatus for the production of drive belts, with a small error in angle of rotation

摘要

In order to produce drive belts with small rotation-angle error, the rotation-angle error of a specific drive belt (6) is measured. Instead of the selection of low-error drive belts, the invention provides that, after the measurement has been performed, the drive belt is physically altered in a part of its length, in such a manner that the rotation-angle error is rendered more or less equal to zero. According to the invention, this physical alteration of the drive belt (6) is realized by the removal of material - effected, for example, by a grinding operation - from the contact surface (7) of the drive belt (6) according to the measured rotation-angle error. For every type of belt, there exists a clear relationship between the rotation-angle error and the amount of grinding required for the correction thereof, it being possible empirically to determine said relationship.
