Abstract
Abstract In this tire making drum of the rind type, described in the copending application Ser. No. 617,658, now abandoned in favor of applicant''s continuation application Ser. No. 28,281, filed Apr. 22, 1970, entitled "Tire Building Machine," each one of the two ends of each spring blade is shaped for receiving a rigid sliding pull member of which the outer end carries means for pivotally connecting the same to a pivot pin carried by the edge of the corresponding flange. The cavity receiving said rigid pull member is formed at either end of the spring blade by a shorter spring blade secured to the former and extending parallel thereto along a distance determined by a small distance piece, said pull member being flat and having a width preferably equal to that of said spring blades; it is guided for longitudinal sliding movement therebetween and retained in either of two end positions by the distance-piece engaging an elongated aperture formed in said pull member.
