Abstract
A rolled paper embossing dispenser comprises a cabinet in which two parallel embossing rollers are rotatably arranged and spring-biased together to define a nip through which a paper web is pulled while being embossed. Each embossing roller comprises a metal axle embedded in a plastic embossing portion. The embossing portion comprises a plurality of axially spaced disks which are axially offset relative to the disks of the other roller. Each disk comprises a plurality of circumferentially successive knuckles interconnected by flats. The knuckles of axially adjacent disks of each roller are circumferentially offset. Both embossing rollers are formed simultaneously in a common mold whereby both plastic embossing portions are subjected to identical molding conditions to achieve identical dimensional tolerances. A threading roller is provided for automatically feeding a paper web into the nip.
