A weigh hopper installation (10) includes a rigid support frame (14) and a hopper (16) having a center of gravity (42) situated laterally adjacent to the frame. Substantially all the weight of the hopper is supported through a load cell (54) carried by a rod (50) between the frame and the hopper, preferably in tension. Restraint members (62, 64, 74) are connected laterally between the frame and the hopper, for preventing horizontal movement of the hopper while permitting vertical movement of the hopper.

A starch based adhesive for use in manufacturing corrugated paper and board is prepared in a single preparation tank 20 by admixing, under high shear vortex mixing, a first portion of aqueous medium, a first starch portion, an aqueous sodium hydroxide, a borating additive, a second portion of aqueous medium and a second starch portion to produce a finished starch adhesive. At least one of the first and second portions of aqueous medium comprises a mixture of fresh water and recycled wash water selected from the group consisting essentially of untreated flexographic printing press wash water, untreated corrugator wash water, and mixtures thereof.
