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.

Claims

1. A striped laminate material comprising a first polyvinyl chloride sheet having a thickness on the order of 6 mils, an open, flexible scrim sheet of serpentine interlaced strands, a second polyvinyl chloride flexible sheet having a thickness on the order of 6 mils, a plastisol bonding agent bonding the scrim between the first and second sheets, and at least one flexible stripe of polyvinyl chloride film having a thickness on the order of 21/2 mils and heat-bonded to the first sheet, the stripe being of a width less than the sheet to which the stripe is heat-bonded, and the stripe being impressed onto the sheet and into the laminate to provide a material having a striped surface of substantial planarity, and an embossed surface on the second sheet on a sheet side opposite the side upon which the stripe is heat-bonded.

2. A striped laminate material according to claim 1 wherein said bonding agent comprises dioctyl phthalate.

3. A striped laminate material according to claim 1 wherein said scrim sheet is a nylon sheet.

4. A striped laminate material according to claim 1, wherein said scrim sheet is a polyester sheet.

5. A striped laminate material according to claim 1, wherein at least one of said first or second sheets is a plasticized polyvinyl chloride sheet.
