This wrapping apparatus comprises a belt nester for wrapping stacks of thin amorphous steel strips about ar arbor. The belt nester includes (a) a belt wrapped about the arbor and movable along its length to impart rotary motion to the arbor and (b) means for successively feeding individual ones of the stacks into the space between the belt and the arbor. The wrapping apparatus further comprises means defining a first substantially-flat surface upon which the stacks are supported as they are fed into the space between the belt and the arbor and additional means defining a second substantially-flat surface extending parallel to the first flat surface. Control means operates when a stack that is being wrapped on the arbor passes between said flat surfaces to bias one of the flat surfaces toward the other and to compress the stack between the two flat surfaces as the stack is wrapped. This compression removes wrinkles from the strips, removes air pockets from between the strips, and enables the stack to be more effectively guided by guide members at the longitudinal edges of the stack.
