Abstract

The present invention is drawn to an improvement in a joining device for joining ends of cord reinforced belt-shaped materials, in which elastic belt-shaped material having a large number of cords embedded therein at equal intervals with a predetermined inclination is cut in the direction of the cords into a length somewhat shorter than an outer circumferential length of a drum to be fed with the belt-shaped material, the cut length being wrapped around the outer circumference of the drum, and the opposite cut end planar surfaces of the material being drawn towards each other and butt-joined by a splicer. The improvement resides in a splicer having a lateral movement device that is movable in a direction parallel to a shaft of the drum, a press device supported by the lateral movement device, and a splice roller pivotably supported at the bottom end of the press device. Also, the improvement resides in the splice roller being in the form of a roller tapered in its radial direction, spring discs fixedly secured to the opposite sides of the tapered roller in which radial slits extend in their outer circumferential portions, and the outer circumferential portions tapered inclined towards the tapered roller. The device of the present invention maintains constant the force for drawing opposed ends of the wrapped material on the drum towards each other.
