Abstract
Official abstract text for this publication.
A bead member manufacturing method for manufacturing a bead member by forming an annular bead filler in an outer peripheral side of an annular bead core includes a step of arranging the bead core on a forming surface of a forming table, a step of forming a first bead filler portion by winding a first rubber in an area closer to an outer side in a width direction than a side surface which does not face toward the forming surface in the outer peripheral surface of the arranged bead core, a step of turning over and rearranging the bead core and the first bead filler portion on the forming surface, and a step of forming a second bead filler portion by winding a second rubber in the outer peripheral sides of the bead core and the first bead filler portion so as to form the bead filler.
First claim
Opening claim text (preview).
What is claimed is: 1. A bead member manufacturing method for manufacturing a bead member by forming an annular bead filler in an outer peripheral side of an annular bead core, the method comprising: a step of arranging the bead core on a forming surface of a forming table; a step of forming a first bead filler portion by discharging a first rubber from a mouth piece having a discharge port shape corresponding to a cross sectional shape of the formed first bead filler portion to the bead core, and winding the first rubber in an area circumscribed by the discharge port and a side surface which does not face toward the forming surface in the outer peripheral surface of the arranged bead core; a step of rearranging the bead core and the first bead filler portion on the forming surface of the forming table or a forming surface of another forming table by turning over the bead core and the first bead filler portion, the step of rearranging the bead core and the first bead filler portion including a step of detaching the bead core and the first bead filler portion from the forming table so as to turn over, and thereafter arranging the bead core and the first bead filler portion on the forming surface of the other forming table; and a step of forming a second bead filler portion by winding a second rubber in the outer peripheral sides of the bead core and the first bead filler portion so as to form the bead filler.
