ABSTRACT:
A waterbed mattress is provided with a series of unitary baffles each comprising a web joined at opposite ends to circular attachment flanges. A floating die of substantially cylindrical form surrounds the central web during the welding process in which substantially flat parts of the welding machine close about top and bottom mattress layers with the baffle and floating die in position. A narrow axially extending slit in the die allows the die to be removed after the baffle is attached. After all baffles are suitably positioned, the mattress layers are closed.
