Abstract
A stacking apparatus includes a feed device that feeds a succession of elongated items to a pick-up station, and a rotating structure having first and second arms at different angles about a rotation axis of the rotating structure. The arms have receiving surfaces mounted thereto that receive the elongated items as a layer at the pick-up station during rotation of the rotating structure as the receiving surface travels past the pick-up station. The apparatus also includes a carriage having layer supporting forks that receive the layer from the receiving surface during rotation of the rotating structure as the receiving surface travels past a layer receiving station. The carriage carries the layer from the layer receiving station and deposits the layer at a layer stacking station from the forks to form the stack of superimposed layers.
