ABSTRACT:
The present invention provides a device to be used in machines which mark workpieces with characters or other symbols and have marking tools for applying the symbols to the workpiece, and elements for selecting the symbols and controlling the movements of the tools to obtain a desired shape and size of the symbols. In the device of the present invention, a lower frame part (1) receives a workpiece (7), and an upper frame part (2) is arranged on the lower frame part. The upper frame is capable of being raised and lowered and supporting the marking tool (43) and the symbol selection and control elements (36-42, 47-52, 69-74) of the machine. During a marking operation, the upper frame part (2) is arranged to rest on the workpiece (7) and clamp it against the lower frame part (1). A marking tool can work on the workpiece through an opening (44) in the upper frame part (2) of the device.
