Abstract: An apparatus for applying tape to a moving press board web including a base for carrying a press board web, a slitter mounted on the base for cutting the web into three strips, a tape applicator for applying a strip of tape to the center strip, the tape being wide enough to overlap the edges of the adjacent strips, a second slitter for cutting the center strip in half and a die for cutting the strips into predetermined lengths.

Abstract: A control system for crane-excavators and the like wherein a metering valve is connected by fluid lines to the control cylinder for the load carrying member, such as a boom or dipper arm. A check valve and a spring biased relief valve are disposed in the fluid line on the down side of the external force created by the weight of the load carrying member on the cylinder. To prevent pressure peaking in both the upside and downside lines, as well as improper check and relief valve operation when the metering valve is moved to neutral, the metering valve is constructed to connect the downside line to the drain tank when the valve is in neutral position.
