Abstract: A linerless label stacking assembly and procedure utilize a paddle wheel first conveyor having a rotatable central portion with a number of paddles extending generally radially outward from the central portion. The central portion is along a generally horizontal axis and is rotated about that axis at spaced time intervals in a first direction.
