ABSTRACT:
A guide rail for a drawing machine carriage has a single part or multipart rack configuration for guiding a carriage with a longitudinally extending slot through which projects the supporting arm of the carriage. In order to achieve simple and reliable dust protection, the slot is provided with a covering element which extends over the slot without impeding the mounting arm. The covering element may be a dustproof sealing lip or a continuous band which is attached to the carriage.
