Abstract
A turn-up device () for making a molded body of an airspring on a mechanical drum having expandable end portions. The device () comprises a support member (), a plurality of turning arms () pivotally mounted to the support member (), and a sleeve () resiliently mounted to the support member (). The turning arms () are movable between radially inner and outer positions and are biased to the radially inner position. The sleeve () is movable relative to the arms () between a position whereat it holds the arms () in the radially outer position and a position whereat it releases the arms () so that they can be biased to the radially inner position. The airspring can be used in a large vehicle wheel suspension (i.e., a bus or a truck) and/or can be used to manipulate the lift axle of, for example, a large dump truck.
