A method and a device for optimal use of windable material during winding up onto and/or unwinding from storage drums operates in conjunction with feeding to winding machines. The windable material can be a textile web, a fabric web, a wire or the like. A counterforce necessary for keeping the tension force acting on the windable material constant is maintained until all of the windable material has been fed into subsequent processing. The counterforce may be maintained by a connecting element that is connected to the windable material and to the storage drum, is able to be wound up, and is of lower quality than the windable material. In the device, controllable means generate the counterforce counteracting the tension force until all of the windable material has been drawn into the subsequent processing device.

A coil feeding device and a graphic machine thereof are provided. The coil feeding device includes a roller mechanism for carrying a coiled material, a base mechanism, and a compression rod mechanism. The roller mechanism includes a shaft penetrating through the shaft hole and a tension structure disposed on the shaft. The tension structure includes a first sleeve, a second sleeve and a tapered fixing member. When the first sleeve and the second sleeve are fixed to each other, the tapered fixing member holds the shaft to achieve mutual fixation of the coiled material and the shaft. By providing the second sleeve, the first sleeve and the tapered fixing member that cooperate with each other, the coiled material and the shaft are fastened to each other quickly, thereby improving production efficiency. Through the base mechanism, the coil feeding device is directly used on existing graphic machine for material processing.
