Abstract:
The invention is directed to an apparatus for making conical bellows for air springs. The apparatus includes a clamping/spreading device transferable between first and second end positions corresponding to an introduction position and a vulcanization position, respectively. The external diameter of the device in the first end position is less than the external diameter thereof of the second end position. The device has clamping segments which in the introduction position are converged so that the external diameter of the device enables an air spring bellows preform to be pushed over the device, and the clamping segments in the vulcanization position are diverged increasing the external diameter of the device so that the bellows preform is pressed tightly against the corresponding external form from the inside. Open gaps because of the enlargement of the external diameter of the device remain between the clamping segments.

Claim (Index 1):
An apparatus for making a conical bellows for an air spring, the apparatus comprising:\n a tool defining a conical surface for receiving said conical bellows thereagainst; a clamping/spreading device transferable between first and second end positions; said device having a plurality of clamping segments which are converged in said first end position to conjointly define a first outer diameter of a magnitude to permit pushing a conical bellows preform over said device thereby introducing said device into said conical bellows preform; said plurality of clamping segments being movable so as to be diverged in said second end position wherein said segments conjointly define a second outer diameter greater than said first outer diameter so as to permit said bellows preform to be pressed by said clamping segments tightly against said conical surface from within said bellows preform during vulcanization; and, each two mutually adjacent ones of said clamping segments conjointly defining an open gap therebetween because of the enlargement to said second outer diameter in said second end position.
