Claim:
A turn-up device for making a molded body of an airspring on a mechanical drum having an expandable end portion with segments that are radially spaced-apart from each other defining spaces when the end portion is in an expanded condition, said device comprising: a support member configured to be movable towards the end portion of the drum; a plurality of turning arms pivotally mounted to the support member, each turning configured to be moved between a radially outer position and a radially inner position and biased to the radially inner position; a sleeve mounted to the support member and moveable relative to the turning arms between a first position where the sleeve holds the turning arms in the radially outer position and a second position where the sleeve releases the turning arms so that they can be biased to the radially inner position, the sleeve includes fingers each having a cam surface, the fingers configured to be aligned with the turning arms for insertion into the spaces between the segments of the expandable end portion of the drum, the turning arms each include a roller which rides on the cam surface as the sleeve moves relative to the arms; and a guide tube mounted to the support member and configured to permit the sleeve to telescopically slide within the guide tube as it moves relative to the turning arms.
