[Also in Group XVI] Apparatus for producing moire or printed designs on a fabric comprises a pattern tool having patterned surface areas which are wetted or moistened with a liquid, and means whereby the fabric is passed first into contact with the wetted surface and then into contact with the spreading tool. The applied liquid is dried by the heated spreading tool before it is spread thereby; hence sharp designs are obtained on the treated fabric. As shown, in the production of a moire design, fabric 2 is drawn over a designing roll 7 provided with zig-zag raised portions 16 which apply a suitable liquid, e.g. water, sulphonic acid, a phosphate, a dextrin, an aniline dyestuff, or an organic liquid, from a trough 8, to corresponding zigzag areas of the fabric. The fabric then contacts a spreading bar 9 provided with ridges 10 which smooth and spread the fabric towards the sides. Bar 9 is heated by steam supplied through a conduit 11, or by other means such as electric resistors, to prevent smearing of the liquid over the borders of the design. Further smoothing and heating is provided as the fabric passes over the surface of a drum 12 provided with a V shaped ledge 13, or a series of such ledges arranged parallelly, and heated by steam supplied through a conduit 14. The treated fabric is then wound onto a rod 4. and subsequently folded and finished by application of heat and pressure in known manner.
