Abstract
Abstract A work position or station including a suctioning device incorporating a suctioning opening for the aspiration of suctionable material which is produced during the processing of workpieces, and a protective plate which guides the suctionable material into the suctioning opening. The protective plate concurrently screens the working personnel carrying out the processing, in particular the head of the person, against the incident suctionable material. The protective plate which is carried by a special mounting support can be moved upwardly prior to the implementing of work without the formation of suctionable material, upwardly away from the suctioning opening in a simple manner into a non-hindering inoperative position.
