<p>The disclosed method and apparatus are related to the machine for and process of cutting a desired contour in a workpiece with an axially traveling elongate tool by relatively displacing the workpiece and the elongate tool transversely to the traveling axis of the latter along a predetermined cutting path describing the contour whereby the workpiece is progressively divided, along the cutting path, into a first portion held secured with a work support and a second portion tending, by its own gravity, to fall off the first. The fall-off is prevented according to the invention with a plurality of attractable members, e.g. permanent magnets, which are spacedly juxtaposed with the workpiece and releasably retained with respective support holders on a support assembly. During the course of cutting of the contour in the workpiece, these members are successively released and propelled from the respective support holders to deposit sequentially at spaced-apart locations on the advancing cutting path so that each of the members firmly bridges the first and second portions across the cut groove.</p> |
