Abstract

In a device for the automatic production of dental replacement parts, a blank 13 is fitted in a substantially plate-shaped carrier body 10 which is so dimensioned that the blank 13 does not exceed the carrier body 10 in any direction. The carrier body 10 serves not only for holding the blank 13 in the working machine but also for protecting it during its automatic handling in magazines or the like. The carrier body 10 is provided with a bar code 20 which relates to the material and dimensions of the blank 13 and may identify data according to which the blank 13 is to be worked The bar code 20 is adapted to be changed by the working machine so as to prevent the carrier body 10 from being reused with the same or a different blank 13.
