Abstract
Abstract A layup machine for assembling panels having a pair of skins and a honeycomb core having a table for stacking panels during assembly which table moves in a vertical direction in increments as the panels are stacked thereon and which table may be raised to remove the assembled panels. A pair of skins, such as sheets of plywood, are fed to the layup machine on knife rollers, after adhesive has been applied thereto and honeycomb core material is placed in the machine. The skins and panels are aligned relative to each other and to the table and at the same time are placed on the table so that the bottom skin will contact and become the top skin of one panel on the table, while the top skin will become the bottom skin for the next panel. Once a stack of panels has been accumulated on the table, they are removed and placed in presses for curing of the adhesive to form a stack of panels. The table is provided with a horizontal feed for removing stacks of panels and the apparatus provides for each of the dropping and aligning means to be moved out of the way for removing a stack of panels from the layup machine.
