ABSTRACT:
An improvement in a contour copying machine having means for supporting at least one pattern and at least one workpiece rotatably about parallel respective pattern and workpiece longitudinal axes, means for synchronously rotating the pattern and the workpiece about the respective axes, at least one copying roller engageable with the pattern, and at least one tool engageable with the workpiece, the copying roller and the tool being rigidly interconnected and synchronously movable about the respective longitudinal axes, and means for urging the copying roller and the tool against the pattern and the workpiece, respectively, for machining the workpiece and accurately reproducing therein the contours of the pattern, the improvement comprising: a rigid support frame for supporting and rigidly interconnecting the copying roller and the tool in proximate relation to one another, traction means connected to the support frame at points thereon situated symmetrically with respect to the copying roller, and biasing means operatively connected to the traction means, the means for urging the copying roller and the tool against the pattern and the workpiece, respectively, including the support frame, the traction means and the biasing means.
