ROLL UP TARP ASSEMBLY ABSTRACT A roll up tarp assembly for a truck having a box with an open top. The assembly includes a tarp support system which is mounted on the open top of the box and a sheet which is located on the support system so that the top of the box is covered. A hollow tube extending longitudinally across the top of the box is provided such that the hollow tube is located substantially centrally with respect to the sides of the box. The hollow tube is placed on top of the sheet and affixed along its length to the sheet. A biasing device is provided within the hollow tube such that the hollow tube is urged to rotate towards a predetermined side of the box and thus roll up the sheet. A locking element couplable to the hollow tube is provided to restrain the hollow tube from rotating when the sheet covers the open top of the box. A drawing device interconnected between the sheet and the box is also provided for drawing the sheet from a rolled up position to an extended position in which the sheet extends over the open top of the box.
