Abstract
At least one supply roll is conveyed by use of a roll support surface. The supply roll can be placed on the roll support surface with its longitudinal axis essentially horizontal. The supply roll can be rolled in at least one conveying direction with its lateral surface on the roll support surface. At least one transport element, with at least one rotating drive device can be brought into contact with the lateral surface of the supply roll from below. The drive device can be driven in at least one conveying direction.
Claims29
A device for conveying at least one supply roll comprising:
- a roll feeding surface, said roll feeding surface adapted to support a supply roll, with a longitudinal axis of the supply roll being horizontal, and with a surface of the supply roll being rollable on said roll feeding surface in at least a first supply roll conveying direction;
- at least first and second driving mechanisms positioned in said roll feeding surface;
- at least first and second conveying elements in each of said driving mechanisms, each said conveying element including an upper surface positioned to cooperate with a surface of a supply roll from beneath the supply roll, each said upper surface having a width, a leading end and a trailing end, said at least first and second conveying elements in each said driving mechanism being parallel to each other and extending in said at least first roll conveying direction;
- means for driving each of said at least first and second conveying elements in each of said driving mechanisms in at least a first driving direction parallel to said at least first supply roll conveying direction;
- a lateral offset between said trailing end of said upper surface in said first driving mechanism and said leading end of said upper surface in said second driving mechanism;
- and
- an overlap between said trailing end of said upper surface in said first driving mechanism and said leading end of said upper surface in said second driving mechanism, said overlap being arranged in said at least first supply roll conveying direction.
