Abstract
Abstract Machinery is provided for use in the building of structural panels and includes a first fixed conveyor, an adhesive-applying station situated relative to the fixed conveyor for applying bonding adhesive to concrete blocks from which the structural panels are to be formed, and a second conveyor having a conveying surface for conveying the blocks to which adhesive has been applied to a platform assembly located adjacent a panelization frame, the second conveyor and platform assembly being longitudinally drivably movable in articulated fashion relative to the first conveyor for longitudinal movement of the platform assembly relative to the panelization frame so that an operator may build a structural panel from blocks conveyed to the platform assembly. The platform assembly includes a vertically and horizontally movable platform. The speed of feed of blocks to the second conveyor from the first conveyor is controlled so that a constant but adjustable rate of delivery of blocks at the platform assembly may be provided.
