Abstract
A positioning and splicing device for paper rolls having at least one carriage arranged to be movable along guides and having an upright on one side provided with slide members for guiding a second carriage that is axially movable along the upright. The second carriage is provided with a spindle for engaging a roll. The roll is raised by a movement of the spindle protruding from the roll and the carriage is moved into engagement in a rotary coupling element that is fixedly mounted, so that the spindle is supported at both ends when the sheet is un-wound from the roll.
