Abstract
A device for supplying a long length of a material such as a metal strip, wire, thread, and the like, having an accumulator between a material supply source which holds and supplies the material and a feeding mechanism which feeds the material to the following process. The accumulator is provided with first rollers pivotally mounted on a fixed bridge, and second rollers pivotally mounted on a movable bridge. The movable bridge moves up and down relative to the fixed bridge. The material supplied from the supply source is passed alternately over the first rollers and second rollers in such a manner that it is led straight up and down, and is then fed to the feeding mechanism. A controlling mechanism controls the material supply source to feed the material, or to stop the feeding, according to the position of the movable bridge.
