  • Patent number: 5788136
    Abstract: The invention relates to a paper roll holder with a brake for dispensing use of paper rolls or the like. The paper roll holder comprises a heavy base to which two column-like parts are fixed, against which the paper roll rests and in between which the paper runs and which at their ends have suitably shaped cutting edges or serration, if the paper web is not perforated. A split ring member including ring and wedge-shaped parts as well as a cover with a spring fixed to it are mounted in bearings to the column-like parts and a spring fixed to the base are all pressing the paper roll against the column-like parts. The form, roughness and weight of the cover and column-like parts the split ring member and the the spring forces of the springs are chosen so that by pulling the paper it easily unwinds but the paper breaks off with a little jerk using only one hand.
