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.
A scanning device for scanning a moulding which has at least one first holding part for fastening the moulding, a tool for cutting a blank, said tool cuts along a circular line of a particular diameter, a scanner having a scanning edge of exactly the same diameter as said circular line, and a second holding part which extends towards the first holding part for fixing the moulding, said scanning edge of the scanner having a recess therein that is of a depth necessary to receive at least half of said second holding part therein.
