Abstract
There is disclosed an inflatable bladder for axially folding a ply at the shoulder of a drum, the body of which bladder carries ply-lifting fingers, as well as a ply-folding wedge in its surface. Inflating means causes the fingers and wedge, after initial expansion of the bladder, to establish and maintain fixed positions against the ply, whereupon the wedge turns a corner carrying the fabric with it. The method of operation is similarly disclosed.
