Abstract
A carriage and track assembly for transferring paper and paperboard rolls along an inclined track. The assembly is useful for the transfer of paper rolls of slippery grades and is based on using a dual track (5, 6) over the length of the inclined section of the transfer track and having compatible wheel sets (3, 4) on the transfer carriage. The front end of the carriage is provided with a wheel assembly (3, 4) in which the rolling perimeter varies at different trackwidths of the assembly. The wheel assembly can be made to run along the inclined sections of said tracks (5, 6) so that in said wheel assembly the rolling perimeters of its wheel sets (3, 4) running on different tracks are vertically located at different heights from the loading platform (1) of the carriage. Thus, the loading platform remains substantially horizontal while the carriage travels along the inclined track.
