In the continuous production of laminates having a texture embossed onto the surface thereof, a pair of resin treated layered webs are brought together at equal speed and an embossed carrier member having a negative of the texture to be embossed thereon is fed between the webs while being unwound from a supply roll. The layered structure formed of the two webs and the carrier member is subjected to compression with subsequent cooling whereupon the outer sides of the laminates are roughened and the webs are formed with a positively embossed or textured surface and are detached from the carrier member and wound on rolls or cut into panels and stacked while the carrier member is simultaneously taken up upon a takeup roll or the like. The carrier member may be moved independently of the webs, i.e., in a reverse direction and the apparatus for manufacturing the webs with the embossed surfaces may comprise a continuously operating double belt press, a spray water cooling system, a grinding station, an unwinding unit with supply rolls, a winding station with rolls, a panel cutting station, a control cabinet having a data terminal and a texturing system consisting of the carrier member, embossing foil rolls and an embossing foil takeup coil.
A process for the manufacture of paper webs for use in the production of laminate materials having embossed surfaces comprising the steps of feeding together a pair of resin impregnated paper webs, feeding to between said webs a metallic carrier member consisting of a hard wear resistant material having two opposed surfaces with an embossing pattern on each of said opposed surfaces to form a layered structure consisting of said carrier member with said webs being applied one against each of said opposed surfaces thereof, compressing said layered structure by applying pressure on each of said webs from both sides of said carrier member, heating said layered structure, subsequently cooling said layered structure, roughening the outer sides of said paper webs and separating said paper webs from said carrier member.
Apparatus for the manufacture of laminate materials having embossed surfaces comprising an unwinding unit including supply rolls for feeding together a pair of resin impregnated paper webs, means including carrier rolls for feeding to between said webs a metallic carrier member having a hard wear resistant surface with an embossing pattern thereon to form a layered structure consisting of said carrier member with said webs on opposite sides thereof, a laminating machine for compressing said layered structure while applying pressure and heat thereto, a spray water cooling device for cooling said layered structure after passage thereof through said laminating machine, a grinding station located downstream of said spray water cooling device for roughening the outer sides of said paper webs, a winding station including rolls for winding thereon said paper webs after passage through said grinding station, a panel cutting station for cutting said paper webs to a desired size, a control cabinet including a data viewer for enabling control of said apparatus and for viewing information indicative of the operating parameters thereof, a carrier member takeup coil for having wound thereon said carrier member after removal thereof from between said webs, said carrier rolls and said takeup coil being arranged to permit forward and backward spooling of said carrier member to enable selective positioning thereof relative to said paper webs.
Apparatus for the manufacture of materials having embossed surfaces comprising:
