Laminated hook fastener

Abstract

An extruded hook fastener strip is created on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll. The second strip is firmly bonded to the fastener strip on that side opposite the formed hooks.

         38 . The product of  claim 37  in which said printing, in pre-applied state on said second layer has been exposed to the conditions of said insitu lamination.  
     
     
         39 . The product of  claim 38  in which the printing lies of the face of said second layer joined to base layer.  
     
     
         40 . A product comprising a field of loop-engageable hooks having stems of molded plastic resin, the stems protruding from one side of a base layer of plastic resin and a second layer joined to the opposite side of said base layer, said second layer bearing printing, the material of which the hook material and base layer is formed being substantially transparent, and said printing being visible from the side of said product having said hooks.  
     
     
         41 . The product of  claim 40  in which said second layer comprises a preformed layer bearing printing on its side adjacent said plastic resin base layer.  
     
     
         42 . The product of  claim 40  in which said second layer is plastic film.  
     
     
         43 . The product of  claim 40  in which said second layer is paper.  
     
     
         44 . A product constructed to engage with material bearing hook-engageable loops, the product comprising a field of loop-engageable hooks having stems of molded plastic resin, the stems protruding from one side of a base layer of plastic resin, and a second layer joined to the opposite side of said base layer, said second layer joined to said base layer by an infusion or diffusion bond with the plastic resin of which said base layer is formed.  
     
     
         45 . The product of  claim 44  in which said second layer comprises preformed sheet of plastic resin.  
     
     
         46 . The product of  claim 44  in which said second layer comprises preformed sheet of paper.  
     
     
         47 . The product of  claim 44  in the form of an insitu laminate, the paper being adhered to the base layer.  
     
     
         48 . A method of making a strip-form product having an array of projections integrally molded with and extending from a side of the product, the method comprising 
 introducing molten resin into a pressure nip defined in part by a surface of a rotating molding roll, the molding roll defining an array of projection cavities extending inward from the surface of the roll, such that the resin is forced into the cavities to mold a corresponding array of projections extending from a base layer of resin solidified on the surface of the molding roll;    introducing a preformed sheet material into the nip with the molten resin, such that the sheet material is permanently bonded to the resin in regions located directly beneath at least some of said upstanding projections, by infusion or diffusion of the molten resin under pressure into the preformed sheet material; and    solidifying the resin on the molding roll; and    stripping the solidified resin and sheet material from the molding roll.    
     
     
         49 . The method of  claim 48  in which the projections overhang the base layer of resin as molded.  
     
     
         50 . The method of  claim 48  in which the projections comprise fastener elements.  
     
     
         51 . The method of  claim 50  wherein the fastener elements are configured to releasably engage loops.  
     
     
         52 . The method of  claim 48  in which the preformed sheet material comprises a non-woven fabric.  
     
     
         53 . The method of  claim 48  in which the base layer of resin forms a continuous layer along the product.  
     
     
         54 . The method of  claim 53  in which the base layer of resin is coextensive in width with the product.  
     
     
         55 . The method of  claim 48  in which the preformed sheet material is coextensive in width with the product.  
     
     
         56 . The method of  claim 48  in which the preformed sheet material forms a backing of the product.  
     
     
         57 . The method of  claim 56  in which the projections comprise fastener elements and in which the preformed sheet material carries engageable loops.  
     
     
         58 . The method of  claim 48  in which the preformed sheet material comprises paper.  
     
     
         59 . The method of  claim 48  in which the preformed sheet material comprises foam.  
     
     
         60 . The method of  claim 48  in which the resin base forms a broad sheet underlying all of the projections.
