Abstract: Crimping machines, including constructions thereof and methods for their manufacture and use. The crimping machines include at least a first load-bearing component that comprises a plurality of load-bearing laminates that are assembled and secured together. The first load-bearing component is installed in the crimping machine so that a crimping load of the crimping machine is imposed on the first load-bearing component during a crimping operation performed by the crimping machine.

Abstract: A method and apparatus suitable for safely and efficiently heating a hose for insertion therein of an attachment. The apparatus includes a heating assembly having at least one hose heater including an electric heating element. The hose heater is adapted to be collapsed, inserted, and expanded into an end of the hose to increase the temperature of the end of the hose.

Abstract: A die carrier assembly configured for use in a crimping machine. The assembly includes die carriers disposed in a circumferential arrangement and adapted for radially inward and outward travel. Each die carrier has oppositely-disposed circumferential extents that define circumferential gaps between adjacent pairs of the die carriers. Shoes are disposed radially inward from the die carriers and are adapted for radially inward and outward travel with the die carriers. The shoes travel radially inward and outward with the die carriers between positions in which the shoes define minimum and maximum openings, respectively, of the die carrier assembly. At least one of the shoes is disposed radially inward from one of the circumferential gaps between at least one adjacent pair of the die carriers. The circumferential extents of the adjacent pair of die carriers define interdigitated fingers that support the shoe when the die carrier assembly is at its maximum opening position.

Abstract: A system and process for performing a crimping operation by which a fitting is crimped to the end of a fluid conduit, and which automatically compensates for one or more variables that can lead to out-of-tolerance crimp diameters, particularly fitting spring-back and crimper deflection. The system and method use a device for inputting into the system a targeted crimp diameter for the fitting, and a crimper for crimping the fitting to the end of the fluid conduit. The crimper comprises a plurality of dies and an actuator for contracting the dies around the fitting to obtain the targeted crimp diameter for the fitting. The system and method further includes a unit for attaining the targeted crimp diameter by automatically compensating contraction of the dies for spring-back of the fitting during crimping and/or deflection of the crimper during crimping.
