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 the 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'.

Pigment-oil suspension ink images are fixed by transferring the images to a transfer paper containing an oil-absorbent masking agent and a physically discontinuous overcoating of a thermoplastic fusing material, and then heating the composite to fuse and fix the images.

Method for fixing ink images

Long hairs of fur pelts known as guard hairs are removed to reveal soft underfur by contacting the pelt with a substrate coated with adhesive and then pulling the substrate away from the pelt. Recoverable or non-recoverable adhesive systems may be used.
