  • Publication number: 20020121537
    Abstract: Dispenser for rolls of a web-shaped material, such as paper, said dispenser having space for at least two rolls (16, 17) arranged substantially horizontally, at which one space is located adjacent the outlet opening (14) and is intended for a first roll in a use position and the second space is located above the first space and is intended for a roll in standby position. A locking means (24, 25;27) is intended to keep the second roll in standby position. The first space is provided with a vertically arranged disk plate (18) having a flange (19) intended to grip around one end of the roll and keep it in use position. The disk plate is spring-loaded (23) and cooperates with the locking means in such a way that when a roll is located in place in the disk plate the locking means (24, 25;27) prevents the standby roll from falling down, but when the roll is removed from the disk plate the locking means can be released and permit the standby roll to fall down to use position in the disk plate.
