Abstract
Abstract A device for feeding materials to be shaped to a shaping tool comprises a rotatable platform supported from its under side. In one embodiment, the device is provided with guide and biasing means which cooperates to provide reciprocal motion to the platform. A piece of shaped material which shape is to be reproduced on a material workpiece is attached to the platform. A guide member is maintained in abutment with the surface of the shaped material while a shaping tool maintained at a fixed distance from the guide member reproduces the shaped surface on the material workpiece.
