US Patent 7857064 Insert sleeve forming device for a recess shoe

A recess shoe system includes a recess shoe an insert sleeve disposed radially inwardly adjacent of the recess shoe in a portion of the recess shoe. The insert sleeve includes a ring and a plurality of fingers extending from the ring, the fingers being radially outwardly deflectable in response to a radially outwardly directed force. The force is generated by a swage in a swaging position acting on an inside dimension of the insert sleeve, and the insert sleeve is radially inwardly retractable when the radially outwardly directed force is removed such that the fingers of the insert sleeve define a tubular structure having an outside dimension smaller than an outside dimension of the swage in the swaging position and method.
