Abstract
A roll of wound material is upended or turned 90° by a pivotable cart and a conventional forklift apparatus. The roll is supported on a pallet and has a central opening which extends substantially vertically. The cart includes a pair of perpendicular walls and a roller which is mounted on the walls adjacent the intersection between the walls. The forklift first loads the pallet and the roll onto one of the walls of the cart which extends horizontally. The forklift is then arranged so that one of its tines is below said one horizontal wall and a second tine is laterally outward of the roller. The forklift is raised to pivot said one wall about the roller until the second wall pivots into engagement with the second tine. The fork lift is then lowered so that the second wall pivots into a horizontal position. The roll is then supported on the second wall with the central opening extending horizontally.
