<p>The invention relates to a paper roll holder with brake for dispensing use of paper rolls or the like. The paper roll holder comprises a heavy base (1) to which two column-like parts (2a) and (2b) 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 ring and wedge-shaped part (3) as well as a cover (5) with a spring (7) fixed to it are mounted in bearings to parts (2a) and (2b) and a spring (9) fixed to the base are all pressing the paper roll against the column-like parts (2a) and (2b). The form, roughness and weight of parts (3) and (5) and the spring forces of springs (7) and (9) are chosen so that by pulling the paper it easily unwinds but the paper breaks off with a little jerk using only one hand. In the roll holder also rolls without core can be used and then springs are not needed, or the holder can be built without the ring-shaped part (3), in which case only springs (7) and (9) press the paper roll against parts (2a) and (2b). The holder is normally placed on the table but can also by transforming the base be fixed to the wall.</p> |
