Abstract
Rolls of paper are stacked in layers without any relative movement occurring between the surfaces brought into contact, using a transfer table which pivots about a horizontal axis, such that the end directed toward the wrapping machine can be swung vertically into different positions corresponding in number with the number of layers to be wrapped and matched in height with a set of tiered stacking tables, the lowest of which is also the longest; with each stacking table occupied by one layer of the paper rolls, the several layers move forward as one, in vertical alignment, to the point where the top layers run off the ends of the shorter tables together and each roll settles plumb on the roll beneath.
