Abstract
A drum for forming relief patterns on a surface of a textile web has a tubular jacket rotatable about an axis and having a substantially cylindrical outer surface centered on the axis and formed with an array of raised portions separated by lands and with a multiplicity of radially throughgoing holes. The holes are elongated and extend at angles between 20° and 170° to midplanes extending perpendicular to the axis, the web engaging the drum. Liquid jets are directed radially inward at the web where it engages the drum for impressing the raised portions into a face of the web. Liquid is aspirated inward through the holes from the web where it engages the drum.
