Abstract
An improved machine for fabricating tire carcasses. The machine comprises in combination a rotatable main drum upon which ply material is laid up; auxiliary drums of a reduced diameter axially aligned at the ends of the main drum to define therebetween a step for the placement of bead rings; electro magnetic bead setters reciprocable from retracted positions axially exterior of the main and auxiliary drums and advanced positions to move magnetically supported bead rings to the step between the drums; bladders positionable between radially interior and exterior positions with regard to main drum whereby their inflation will turn up the edges of the ply material to encompass the bead rings at the steps and fabricate the tire carcass; bladder cages reciprocable to guide the inflation of the bladders; drive means to reciprocate the bladder cages between the retracted and advanced positions; and means to couple and uncouple the bladder cages and bead setters whereby the bead setters may reciprocate with the bladder cages during the bad setting and the bladder cages may reciprocate independently of the bead setters during edge turn up. Also disclosed is a method of fabricating tire carcasses.
