ABSTRACT:
A method and apparatus are disclosed for wrapping a load conforming generally to a rectangular solid, such as a cotton bale. Lengths of wrapping film from two rolls are welded to form a predraped wall of such film, into which the load is conveyed to cover its front face and its lateral faces, whereupon the welded lengths are welded again behind the bale and are severed from such rolls. As the load is conveyed, a length of wrapping film from a third roll is wrapped in a spiral pattern so as to cover the upper, lower, and lateral faces of the load. Moreover, generally V-shaped perforations pointing toward the front face are formed in the lateral faces, by means of perforating mechanisms. Each mechanism comprises a pivotal arm biased toward the load, a wheel rotatable on the arm, and perforating cutters extending radially from the wheel, in two circumferential arrays.
