ABSTRACT:
A capping head for a core-capping apparatus adapted to fix conforming sleeves within tubular fiber cores is constructed from a one-piece cylindrical shell having a bore therethrough to accommodate axial sliding movement of a partially conical, power actuated, tapered ram. Independent, individual punches and crimping heads are extensibly and retractably seated within recesses formed in the periphery of the shell and operatively communicate with the tapered ram through respective ball bearings located in guide passages which extend radially outward from the bore of the shell so that linear axial movement of the tapered ram within the shell causes corresponding linear, radially outward movement of the ball bearings and their respective punches and crimping heads, extending the punches and crimping heads outside of the periphery of the shell. The punches and crimping heads have respective retraction devices to cause them to retract within the periphery of the shell when allowed to do so by the position of the tapered ram. The bore of the shell is substantially sealed from the outside of the shell so that the innermoving parts may operate in a lubricated environment.
