  • Patent number: 5911846
    Abstract: The invention eliminates the drawbacks that strip-like members develop curling sets during storage and that the amounts of shrink of strip-like members vary, and minimizes the amounts of remnants of strip-like members after formation of one lot and the number of length measuring and cutting devices for strip-like members. A strip-like member 12 is formed in long size and cut into predetermined lengths during transfer on conveyers 13 an 14. The resulting strip-like members 12 of predetermined length are placed one by one on smooth-surfaced pallets 20, the latter being transferred to a tire building machine. One end of such strip-like member 12 on the pallet is brought into contact with the lower surface of the building drum 30. The building drum is rotated while the pallet is moved in the direction of the length.
