Abstract

A moulding is contacted by two end pieces of a rotatable first holding part and is scanned by a disk. For the suppression of relatively large elastic deformations of the moulding by the pressure exerted by the disk, the moulding is also contacted by a second holding part which is located opposite the first holding part, extends into two tips and is mounted so as to be rotatable. For allowing an uninterrupted scanning, the disk is provided with a radial slot which, when the surroundings of the area contacted by the second holding part are scanned, receives said second holding part. The scanning device can be used for the direct copying of the moulding, rotations of the first holding part being transmitted via bevel gears and a shaft to a fastening bearing a blank and a rotating grinding disk of the same dimension as the disk being moved analogously to said disk.
