Abstract
Apparatus for expanding resilient tubing includes first and second pins, sized to be received into the tubing to be expanded. The second pin, extending from a carriage, is separated from the first pin by the movement of the carriage from a first position adjacent the first pin to a second position spaced apart from the first pin. The carriage is impelled by a foot-switch actuated air cylinder.
