Abstract
Abstract A striped, flexible laminate sheet is disclosed, together with a method and apparatus for making the sheet. The sheet can include first and second plies, and an intermediate open woven scrim bonded together by a plastisol bonding agent. Atop one ply are heat-bonded one or more relatively narrow and thin polyvinyl chloride stripes. This product is manufactured by paying out sheet webs and applying a bonding agent to an underside of the top ply. Stripe material is payed out atop the top ply from payout rolls journaled on mounting arms. A heat roll and opposing nip roll join the laminate plies and simultaneously heat bond the stripe material to the top ply. The striped laminate web is then directed through chilling rolls where a web surface can be embossed with a pebbled or grained surface. After inspection, the product is wound upon a takeup roll.
