Abstract
An automated process of making reinforced roof and wall sheets for trucks and trailers employs step-by-step advancement of the sheet rock and lateral infeed of the structural reinforcing members. As the reinforcing members are sequentially fed into registry with the sheet stock, two kinds of adhesive are applied to them, one being a hot melt adhesive and the other being a catalyzed room temperature curing adhesive. The hot melt adhesive sets to provide an initial bonding which allows normal handling while the room temperature curing adhesive cures in the joint ultimately to augment the hot melt and provide a high strength joint.
