リップへのＶ形ブロック組付装置。A flexible endless strip and a receiving surface between a pair of stopper mounting protrusions are opposed to the inner circumferential surface of the endless strip, and both protrusions sandwich both side edges of the endless strip, and along the inner circumferential surface of the endless strip. A plurality of V-shaped blocks are arranged close to each other, and the V-shaped blocks are attached to both protrusions of each V-shaped block.
a plurality of elastic stoppers for assembling the shaped block to the endless strip, each stopper having a presser portion facing the outer circumferential surface of the endless strip, and a presser portion located at both ends of the presser portion and attached to the endless strip on the outer surface of both protrusions. A device for assembling the V-shaped block to the endless strip in an endless power transmission belt having a pair of engagement portions that engage in engagement grooves extending in the circumferential direction, the strip holding the endless strip in an annular shape. The holding mechanism holds the V-shaped block in a collapsed state on the inner circumferential side of the endless strip, so that the opposing inner surfaces of both protrusions are substantially parallel to the circumferential direction of the endless strip, and the receiving surface is approximately parallel to the generatrix of the circumferential surface of the endless strip. A plurality of block holders that are orthogonal to each other and can be raised and lowered to be transferred in the circumferential direction of the endless strip, and a plurality of block holders that are arranged on the outer circumferential side of the endless strip in correspondence with each block holder and that are in a laid down state, move the stopper to both engaging portions. a plurality of movable stopper holders which are positioned in a plane substantially parallel to the plane in which both the engaging grooves of the V-shaped block exist and are moved in the circumferential direction of the endless strip; and the corresponding block holders and the stopper holders. When the V-shaped block is stood up, both protrusions of the V-shaped block sandwich both side edges of the endless strip, and the tips of both engaging portions of the stopper are aligned with the V-shaped block.
A block holder erecting mechanism and a stopper holder erecting mechanism respectively engage the ends of both engagement grooves of the V-shaped block, and a block holder erecting mechanism and a stopper holder erecting mechanism are provided, which lower the stopper holder and collide with the stopper to cause both engaging portions to engage with both engagement grooves of the V-shaped block. A device for assembling V-shaped blocks to an endless strip in an endless power transmission belt, comprising: a stopper holder folding mechanism that is installed in each matching groove; and a block holder folding mechanism that folds down the block holder.
