Abstract

An auxiliary device is intended to be added to an injection moulding device for manufacturing disc-like information carriers, which injection moulding device comprises: a mould (3) having at least two mould parts (4, 5) displaceable relative to each other, which in a first relative position bound a mould cavity (10), the form of which corrsponds with the form of the information carriers for manufacture, into which mould cavity debouches a feed for heated plastic, and which in a second relative position are located at a distance from each other such that the mould cavity is accessible; positioning means for holding in a desired position an information component (13), for example a plate for placing against an end wall of the mould cavity, on which plate is found the information to be recorded onto the information carrier, which information component (13) remains in position relative to the mould cavity when a formed information carrier is removed; which auxiliary device comprises: a supply holder (15) in which can be received at least one information component (13); transporting means (20, 21) for transporting successive information components (13) between the supply holder (15) and the mould (3).
