Abstract

1,202,238. Tyre building machines. CONTINENTAL GUMMI - WERKE A.G. 19 Sept., 1967 [6 Dec., 1966], No. 42664/67. Heading B7C. A tyre building machine comprises a drum having a hub 5, end walls 6, 7 and an inflatable diaphragm 8 fixed to walls 6 and 7, the walls being mutually axially adjustable symmetrically to remain evenly spaced from the drum midcircumferential plane, wall 6 by axial movement of support shaft 1 and wall 7 by sliding on hub 5. Shaft 11 with oppositely threaded parts 13, 14 engaging a disc 15 rotatable on shaft 1 and a sleeve 17 fixed to wall 7 is rotated by shaft 12 to move the walls. Member 22 carried by hub 5 is turned to engage wall 7 with bayonet connection by sleeve 23, whereafter sleeve 20 may be moved to the right freeing hooked ends 18 of sleeve 17 to spring out of groove 19 in wall 7. Thus the drum may be removed entire from the shaft 1 after removal of a lock ring 10.
