发明名称	Anordning och förfarande för framställning av hårdkartong av flerbelagt papper genom användning av relativ rörelse av motstående banor
摘要	<p>Apparatus and process for fabricating pressboard from shredded paper coated with a thermoplastic material and a pair of facing webs includes placing the shredded poly-coated paper (18) between the two travelling webs (12,14) to form a composite, the composite then being passed in a manner to differentially shift the travelling webs relative to each other for enhanced bonding of the shreds to themselves and to the facing webs, by pressing them through a series of heated rollers (46-52) defining a serpentine path while heating the thermoplastic material above its softening point, and pressing the composite together.</p>
