ABSTRACT:
An apparatus for making a single face corrugated board having two fluted mediums bonded together at the flute tips has (a) mill roll stands for two mediums and one liner; (b) a carrier roll fluted to support a first fluted medium; (c) a single corrugating roll of diameter not larger than the carrier roll engaging with the carrier roll to corrugate the first fluted medium; (d) a pair of corrugating rolls of diameter no larger than the carrier roll adapted to produce a second fluted medium, the pair being located and driven relative to the carrier roll to enable the first and second fluted mediums to be brought into flute tip to flute tip contact and to be conveyed by the carrier roll, the axes of the corrugating rolls not lying in a plane common with the single corrugating roll or the carrier roll; (e) a first adhesive application station to apply adhesive to one of the fluted mediums prior to the flute tips of the first and second fluted mediums coming into contact; (f) a second adhesive application station to apply adhesive to the exposed flute tips of the bonded mediums or to a liner board; (g) a liner applicator roll located adjacent to the carrier roll downstream of the second adhesive applicator positioned to lead a liner board into contact with the bonded fluted mediums without application of pressure; and (h) an energy radiator unit located adjacent the carrier roll downsteam of the liner applicator to accelerate curing of the adhesive bond between the liner and the mediums.
