Abstract
ABSTRACT
TITLE: WALLCOVERINGS
Pieces (15) of prepasted foamed wallcovering are made in a two-location process. At the first location a web of paper substrata (10a) with a formable coat (10b) is given a print (10c). At the second location the printed web is given a pre-paste coat (10d) with an adhesive capable of providing remoistanable features after tolera-ting heat conditions to be encountered during a subsequent foaming step, and the pasted, printed web is then given at the same location any subsequent treatment required (such as embossing) including heat-ing to generate the foam.

(a) providing the paper substrate with a ground coat.
(a) providing the paper substrate with a ground coat.
5. A process as claimed in Claim 3 or 4 further including:
(a) embossing the printed and pasted web prior to the said heating-to-foam step.
(a) embossing the printed and pasted web prior to the said heating-to-foam step.
6. A process as claimed in Claim 1, 2 or 3 in which:
(a) foaming the web in a temperature range of between 180° C to 220° C for 15 to 40 seconds.
