Abstract
The specification discloses a crimping process for crimping a metal ferrule (19) onto a hose (17) including the steps of applying a radially inwardly directed crimping force to die elements (16) adapted to engage the ferrule (19) and increasing said crimping force to a first level over a first period of time, at least partially removing the crimping force from said die elements after said first period of time, and reapplying the radially directed crimping force to said die elements (16) and increasing said crimping force to a second level over a second period of time, said second crimping force level being equal to, higher or lower than said first level, and at an end of the crimping process, removing the crimping force fully from the die elements (16).
