Abstract

A method for dry heat transfer printing a wall covering material utilizing a system comprising at least one transfer cylinder having a heated working surface, comprising processing a non-woven fibrous web material in paper form in overlapping contact with a sublimation dye transfer paper having a decorative pattern to be printed, around a portion of the working surface of the transfer cylinder between a first location and a nip roller engaged against the working surface which exerts a rolling force against the web material, the transfer paper and the working surface as the transfer cylinder rotates about a central axis thereof, at a processing temperature to effect transfer of the decorative pattern from the transfer paper to the web material, the system including a tensioning mechanism disposed proximal the first location, which, in combination with the nip roller, maintains the web material at a sufficient tension to preclude lateral movement of the web material during processing of the web material and the transfer paper on the cylinder, and separating the web material containing, the printed decorative pattern from the transfer paper at a second location proximal to the nip roller.
