Abstract
A method for continuously feeding tire constituent materials in a tire fabricating machine includes the steps of positioning a second material truck holding a new roll of material at a standby location at the rear or to the side of a material feeder as aligned therewith, holding a trailing end portion of old rolled material being used for the tire production on a first material truck disposed in the material feeder before the material being used is consumed, delivering the first material truck when empty to the front, the side or the rear of the material feeder, transferring the second material truck holding the new roll of material into the material feeder from the rear or the side of the material feeder, delivering a leading end portion of the new rolled material on the second material truck once disposed in the material feeder up to a preselected position, splicing the trailing end portion of the old material being held to the leading end portion of the new material along a location where the respective end portions overlap with each other while releasing the trailing end portion, and successively repeating such steps. The present invention is also drawn to apparatus for carryin…
