The utility model has the advantages that: 1. the utility model provides a belted layer laminating drum mechanism that both sides supported, the both ends of the rubber belted layer that appears when having solved among the prior art laminating rubber belted layer can appear flagging problem, have improved the effect of laminating, have avoided the folding phenomenon at turn-up in-process rubber laminating layer both ends simultaneously. 2. The middle sliding seat is driven to move axially by the push rod, so as to drive the left sliding seat and the right sliding seat to move coaxially, further pushing the left slide block, the middle slide block and the right slide block to do radial motion simultaneously to realize the simultaneous radial expansion of the left drum plate, the middle drum plate and the right drum plate, then performing a winding procedure on the belted layer, inflating the air cylinder after winding, pushing the left slide seat to slide by the air cylinder, driving the right slide seat to slide together by the left slide seat under the action of the stop lever, further radially expanding the left drum plate and the right drum plate again, wherein the drum surfaces of the left drum plate and the right drum plate are higher than the middle drum surface and equal to the height of the belt layer after winding, when the tread layer is attached again, the width of the support lack at the two sides of the belted layer is filled, the two ends of the tread layer can be compressed, the reject ratio of tire production is reduced, the product quality is improved, and the product cost is reduced. 3. Through gag lever post and adjusting nut, can inject the difference in height of left drum plate and right drum plate 2 times when expanding with middle drum plate to the demand of adaptation not unidimensional product.
