Abstract

PURPOSE: To efficiently mold a tread band of a high quality by pasting a continuous tread band on a molding drum, and thereafter cutting the tread band into a preselected length immediately bofore the pasting to bond the cut surfaces to each other.
CONSTITUTION: The molding device is provided with a molding drum 110 capable of expanding and contracting its diameter and intermittently rotating at a specific angle, and a holding mechanism 75 for holding a tread band in a manner approachable and separable to and from the drum. The molding device is further constituted by a cutting mechanism 143 for cutting the tread band in a predetermined length while the holding mechanism holds the tread band, a carrying mechanism 191 which is approachable and separable to and from the drum and carries the end parts of the cut tread, and a pressing roll 199 for press-fitting the tread band cut into a predetermined length, both cut surfaces are bonded immediately, and therefore the aging contraction of the tread pieces is prevented and the tread band of a high precision can be formed.
