(54)	Adhesive binding of paper

(57) A method of forming an adhesively bound block of paper sheets is described, in which the binding edge margins (7') of the sheets are abraded to a rough surface by a rotating wire brush 3, or abrasive belt or roller, before binding to provide a good key for the adhesive. The binding edge margins of the sheets may simply be roughened, or they may be abraded to a desired profile.
