Abstract: There is disclosed a machine for crimping a coupling onto the end of a hose over which the coupling is coaxially fitted. The hose and coupling are inserted through an annular crimping head and positioned on a coupling support. Two semicircular arrays of circumferentially spaced-apart crimping dies are respectively carried by two pivotally mounted part-cylindrical die-holding jaws which open to facilitate insertion of the hose and coupling and close to form a circular array of dies surrounding the coupling, each die being radially slidably movable with respect to the associated holding jaw. As a hydraulic drive cylinder draws the crimping head toward the dies, cam means close the die-holding jaws and the crimping head then moves into surrounding camming engagement with the dies for moving them radially inwardly into crimping engagement with the coupling. A safety valve limits the force applied to the crimping head until the die-holding jaws have closed.
