Abstract
Radial compression mechanism includes a housing defining an inner chamber and a central opening for insertion and removal of product. A plurality of elongated compression dies are movably mounted for reciprocal movement within the inner chamber and define a central product receiving cavity coaxial with the axis of the central opening. Cam followers are affixed to the dies. First cam surfaces are affixed relative to the housing and second cam surfaces are movably mounted relative to the housing. Each cam follower engages a first cam surface to define a first position control constraint, and a second cam surface to define a second position control constraint. Each die has a position relative to each adjacent die and the coaxial central cavity that is controlled by the first position control constraint and the second position control constraint.
