摘要： A fastening apparatus adapted for use with chock and a roll which locates within the chock such that a first end of the roll projects through and beyond a first end of the chock and a second end of the chock is located relative to the roll. The apparatus comprises a housing, a piston movably situated within the housing to allow a plurality of circumferentially spaced locating portions of the piston to be retained within the housing or to project through corresponding openings in the housing, pressure means provided within the housing to act on the piston, and at least one fastening member attached to the housing. In an operative position of the apparatus the housing is placed between the first end of the chock and the first end of the roll, and the pressure means acts between the piston, forcing the locating portions of the piston into location with the first end of the chock, and forcing the at least one fastening member into location with the first end of the roll. Thus the first end of the roll is forced away from the first end of the chock and, with location of the second end of the chock relative to the roll, the chock and roll are fastened relative to each other.
