Abstract
In assembling a three-layer sandwich for the manufacture of a laminated board, a first sheet designed to form the bottom layer is picked up by a horizontally movable gripper from a repository at one side of a stacking table and is pulled by the gripper across that table while a pronged carrier picks up a second sheet, designed to form the middle layer, from a roller track at the opposite side of the stacking table. As the gripper reaches the end of its transfer stroke, it magnetically links up with the pronged carrier to entrain same across the stacking table during the return stroke of the gripper so as to align the second sheet with the first one. Next, the gripper seizes a third sheet, designed to form the upper layer, at the repository and pulls it over the stacking table where the second sheet is being retained by stripping lugs as the carrier returns to its loading position. Finally, the carrier lowers its prongs preparatorily to picking up a further sheet from the roller track while the gripper, now decoupled from it, moves back toward the repository for the start of a new cycle as the three stacked sheets are engaged by edge-clamping jaws and removed from the table to a laminating press.
