ABSTRACT:
A method and apparatus for starch adhesive bonding of paper, paperboard, and natural cellulosic-fiber materials, especially liner and fluted corrugating medium, into manufactured items, particularly corrugated board. The method includes applying an adhesive coating, comprising starch and water, to a first substrate (e.g. tips of flutes of a corrugated medium), contacting the applied coating with another substrate (e.g. liner) and while so positioned contacting an exterior surface of at least one of the substrates with an ultrasonic energy generating means so as to transmit ultrasonic energy to the adhesive coating to increase coating adhesion to the substrates. The apparatus includes ultrasound means (10, or 37,37', or 43,43', or 55,55', or 61,61') forming a nip with an anvil 16, or roll 35 or 44, or drive means 57 or 62, with the nip including therebetween paper 17/ starch adhesive 19/ paper 18, or liner 30 or 50/ starch adhesive 32/corrugated medium 31 or 51, or liner 40 or 60/ starch adhesive 32'/ single faced corrugated board 34' or 52'.
