Abstract

Floor panel, which on the bottom side is provided with a factory-applied glue which substantially consists of synthetic rubber. The invention also relates to a method for manufacturing such floor panels, wherein the glue is applied by means of a roller device.

Claims

exact text as granted — not AI-modified
1 . Floor panel, characterized in that this floor panel on the bottom side is provided with a factory-applied glue substantially consisting of synthetic rubber. 
     
     
         2 . Floor panel according to  claim 1 , characterized in that the glue substantially consists of butyl rubber. 
     
     
         3 . Floor panel according to  claim 1  or  2 , characterized in that said glue is covered by means of a foil. 
     
     
         4 . Floor panel according to any of the preceding claims, characterized in that said glue forms a layer on the back side of the panel concerned. 
     
     
         5 . Floor panel according to any of the preceding claims, characterized in that said glue has a maximum thickness of 1 millimeter or less. 
     
     
         6 . Floor panel according to any of the preceding claims, characterized in that this floor panel has a thickness of 5 millimeters or less. 
     
     
         7 . Floor panel according to any of the preceding claims, characterized in that this floor panel substantially consists of synthetic material. 
     
     
         8 . Floor panel according to  claim 7 , characterized in that this floor panel substantially consists of compact laminate. 
     
     
         9 . Floor panel according to  claim 7 , characterized in that this floor panel substantially consists of thermoplastic material, such as polyvinyl chloride or polyurethane or polypropylene. 
     
     
         10 . Floor panel according to any of the preceding claims, characterized in that this floor panel is waterproof. 
     
     
         11 . Floor panel according to any of the preceding claims, characterized in that this floor panel is provided with a profile on at least two opposite edges, wherein the profiles of these edges allow aligning two of such floor panels in mutual respect in a vertical direction perpendicular to the plane of the floor panels and/or in a horizontal direction perpendicular to the respective edge and in the plane of the floor panels. 
     
     
         12 . Method for manufacturing floor panels according to any of the preceding claims, characterized in that said glue is applied by means of a roller device.
