Abstract: Apparatus for preparing a single starch component corrugating adhesive. An aqueous slurry of starch is treated with caustic under controlled temperature conditions, so as to produce a partially swollen starch corrugating adhesive mixture. Swelling of the starch granules is terminated at a preselected viscosity by the addition of a material such as alum, boric acid, ice, other acid material or the like.
