ABSTRACT:
Machine for sequentially rotating and tilting a container having materials therein for wetting or impregnating a tape to be used for forming an orthopedic cast, the machine having a turntable rotatable about a horizontal axis, a platform on the turntable for receiving the container base and rotatable about an axis transverse to the turntable axis and a clamp on the turntable for clamping the container on the platform. The turntable is rotatable by a first motor and the platform is rotatable by a second motor mounted on the turntable. The first and second motors are sequentially energized by a motor driven timing means to (a) tilt the container from its upright position to a position 45.degree. from the vertical, (b) intermittently spin the container, (c) invert the container, (d) spin the container, (e) return the container to its upright position and (f) spin the container. To eliminate slip rings for energizing the second motor the turntable is rotated in opposite directions in steps (a) and (e) by a rack and gear drive between the first motor and the turntable.
