According to the invention, in a sheet feeder for office machines, the feed shaft (11) and/or the integral feed members (12) have at least one outer peripheral annular friction band (12.1) consisting of a surface coating comprising at least one layer consisting of at least one synthetic resin or at least one water-based varnish, containing at least one evenly distributed surface roughening means in powder or granule form. The following stages are carried out in order to form the said band: a coating layer is deposited on part of the surface of the shaft and/or of each feed member, applying at least one synthetic resin in the liquid state or a solution of at least one water-based varnish, using conventional application means; at least one additive in powder or granule form and constituting the surface roughening means is then applied in a uniform layer onto the said coating layer while it is still wet and acts like an adhesive; it is then allowed to dry.
