Abstract: A paper feed device for use with a rotary press for printing newspapers includes a plurality of guide rails connected together so as to extend along any of different paper feed paths. A linear member is inserted into the guide rail so as to be fed through guide rails extending along a predetermined paper feed path. A lever has its one end secured to one side of the linear member and is provided at its other end with a clip for detachably engaging a paper coupling adaptor holding the leading end of a web of a paper roll stored in a paper feed unit of the rotary press. The linear member is moved along the guide rails by pairs of driving and driven wheels arranged at equal intervals along the guide rails. The linear member has a length slightly larger than the distance between the adjacent pairs of wheels.
