Abstract A machine for the colour printing of textile webs or structures such as carpets and tiles which are tufted or non-woven wherein the colour is sublimatic dyestuff carried by a printing foil and this is placed over the textile structure with the dyestuff facing the textile structure to form a sandwich. Heat is applied by a heating plate to vaporize the dyestuff, and an air flow through the sandwich is created by making the heating plate of sintered, air permeable metal, supporting the sandwich on an air permeable support, and by creating an air pressure differential across the sandwich. The support includes a grid plate on which the textile web is supported and there is an evacuation chamber under the grid plate to assist in producing or for producing the air flow. The chamber and heating plate are movable apart for loading and unloading of the machine.
A transfer printing press comprising a press platen in the form of an air permeable, sintered metal plate, an air permeable support platen means located in face-to-face relationship with the press platen, pressure means adapted to press a sandwich comprising an air permeable sheet structure to be printed and a sublimatic printing foil between the sintered metal plate and the support platen means, heating means for heating the sublimatic printing foil through the sintered metal plate to release the dyestuff from the printing foil, and means for creating a flow of air through the sintered metal plate, the sandwich of foil and sheet structure, and the support platen means when the dyestuff has been released from the printing foil.
