Abstract
Abstract Disclosed is a method and apparatus for providing surface replication in a coating on a sheet material. The method comprises the steps of: A. applying a flowable coating of a settable composition or material to one side of a web of sheet material; B. pressing the coated side of the sheet material against a replicative surface having a desired contoured surface effect of peaks and valleys to cause the surface of the coating to conform to the replicative surface; C. setting the coating to a nonflowable state at least sufficiently to enable it to be removed from the replicative surface securely attached to the sheet material and with the replicated surface effect in the coating being maintained; and D. stripping the sheet material from the replicative surface with the at least partially set coating adhered to the sheet material, characterized by the replicative surface comprising a cylinder having the desired surface effect in the central portion of its outer cylindrical surface and extending laterally less than the width of the sheet material on both sides and being bordered on both sides by cylindrical bands of a smooth surface extending beyond the width of the sheet material and having a diameter no less than the diameter of the valleys of the contoured surface effect area, and the coating extending laterally into the area of the smooth surface bands, whereby the set coating material fills all of the desired surface effect area and is stripped cleanly from the replicative surface and the smooth surface bands.

A method of providing surface replication in a coating on a sheet material, comprising the steps of: A. applying a flowable coating of a settable composition or material to one side of a web of sheet material; B. pressing the coated side of the sheet material against a replicative surface having a desired contoured surface effect having peaks and valleys to cause the surface of the coating to conform to the replicative surface; C. setting the coating to a nonflowable state at least sufficiently to enable it to be removed from the replicative surface securely attached to the sheet material and with the replicated surface effect in the coating being maintained; and D. stripping the sheet material from the replicative surface with the at least partially set coating adhered to the sheet material, characterized by the replicative surface comprising a cylinder having the desired surface effect in the central portion of its outer cylindrical surface, said surface effect extending laterally less than the width of the sheet material on both sides and being bordered on both sides by cylindrical bands of a smooth surface extending beyond the width of the sheet material and having a diameter no less than the diameter of the valleys of the contoured surface effect area, and the coating extending laterally into the area of the smooth surface bands, whereby the set coating material fills all of the desired surface effect area and is stripped cleanly from the replicative surface and the smooth surface bands.
