Patent ID: 7140218

Claim:
A rolling apparatus which performs rolling processing of a ring in an endless metallic belt formed by annularly arranging multiple elements in a plate thickness direction, and passing the ring through each of saddle portions of the elements, comprising: a pair of rollers which hold the ring with the ring being sandwiched therebetween, and which roll the ring, and a roller which applies tension to the ring; a measuring device that measures a temperature of the ring before rolling; a rolling load controlling device that controls a rolling load which the pair of rollers apply to the ring; a tension controlling device that controls a tension which the roller applies to the ring; a storing device that stores, in advance, a relation between the temperature of the ring, the rolling load and the tension; and a controller that calculates the rolling load and the tension based on the measured temperature of the ring and the relation, and that controls the rolling load controlling device and the tension controlling device.
