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. Each paddle has first and second curved surfaces which engage the linerless labels for stacking. A second conveyor having a generally horizontal supporting surface is disposed at approximately the same vertical position as the first conveyor axis, and a rotary cut off device, or a similar individual label cutter, feeds linerless labels to the first conveyor one at a time. After a stack of predetermined size is formed on a paddle, a controller (which receives input from a sensor associated with the rotary cut off) controls motors to rotate the first conveyor and operate the second conveyor to advance a stack of labels away from the cut off device.
