ABSTRACT:
An apparatus for effecting the coloration of synthetic textile materials, at a reduced pressure, by a transfer process which comprises a pair of opposed rigid platens mounted for relative movement towards and away from each other, means for heating at least one of said platens to a temperature above 100.degree. C, means for enclosing at least a portion of the space between the opposed surfaces of said platens when the platens have been moved towards each other into a closed position and means for reducing the pressure, within said portion, when the platens are in closed position, to below 100 mm of mercury, one of said platens being supported from at least one flexible diaphragm which is supported and sealed at its edges, the space on the side of the diaphragm from which the platen is supported being connected to the gas tight region between the platens whereby relative motion between the platens is effected by the differential pressure that is established across the diaphragm when the pressure in the gas tight region is reduced.
