Abstract: In a spraycoating apparatus for round workpieces such as drums, the drums are supported on turning cones while being sprayed. The turning cones are supported on pins moved round in part of a circle from an inlet to an outlet about a horizontal axis. Spray units for putting on the spraycoating material are able to be changed in angle and to undergo adjustment.

Abstract: Disclosed is an apparatus and machine for center drilling rod or rod-like materials, and a method for simultaneous center drilling of both ends of a rod or rod-like materials by using the disclosed apparatus and machine having a frame supporting a first centering cone mounted stationary to said frame, a second centering cone movably mounted to said frame for movement along an axis extending between said first and second centering cones, an adjustable and movable workpiece rest mounted to said frame for supporting a rod-like member along said axis, first and second center drilling means each movably mounted to said frame and each adjacent to and cooperating with a centering cone for center drilling of the ends of a rod-like member, adjustable sensing means for controlling the extent of center drilling at each end of a rod-like member and means for hydropneumatic movement of said movable centering cone along said axis.
