Abstract
Abstract The shingling device includes a feeder, a rotating hub having grasping members thereon, a first conveyor, and a second conveyor adapted to move more slowly than the first conveyor. The grasping members are adapted to move by the feeder, grasp sheet members from said feeder, and deposit the sheet members on the first conveyor. The first conveyor carries the sheet members to the second conveyor and deposits them on the second conveyor. The sheet members stack up in shingle-like arrangement on the second conveyor because the second conveyor is moving substantially slower than the first conveyor.
