An apparatus and method for bundling shingles includes a sorting mechanism for separating and stacking shingles into multiple bundles of sorted shingles such that each bundle has a different repeating sequence of shingles.

Three-around cutting pattern for title roofing material

In a method of cutting roofing shingles, multiple webs of roofing material are moved to a cutter. The webs are positioned in stacked relationship prior to the cutter. The webs have distinct portions such as tabs. The locations of the distinct portions of the moving webs are sensed by sensors. End cuts are simultaneously cut through the multiple stacked webs with the cutter to produce separate roofing shingles from the webs. The movements of the webs are controlled, based on the sensed locations of the distinct portions, so that the end cuts of the roofing shingles are positioned at predetermined locations relative to the distinct portions.

Controlled cutting of multiple webs to produce roofing shingles

An apparatus for dispensing granules onto a moving asphalt coated sheet includes first and second granule feed chambers containing granules that are fed to a discharge slot by first and second pockets. The pockets are formed in a slidable divider positioned between the feed chambers and the discharge slot. The divider is slid between a first position and a second position by a fluid powered actuator via an actuator rod. In the first position, the first pocket is in communication with the first granule feed chamber to receive granules from the feed chamber and the second pocket is in communication with the discharge slot for discharging the granules contained in the second pocket. In the second position the first pocket is in communication with the discharge slot for discharging the granules contained in the first pocket and the second pocket is in communication with the second feed chamber to receive granules from the feed chamber.
