摘要

A device for printing in a continuous manner upon a web of textile material by sublimation of the dyestuff of a dyestuff carrier which is pressed against the web of textile material and which during the printing operation is by a pressure belt pressed into engagement with a heated surface of a drum over which the dyestuff carrier passes. The pressure belt is permeable to air and other gaseous substances whereas the heated engaging surface of the drum or the dyestuff carrier is air or gas impermeable. According to a particularly advantageous embodiment of the above mentioned device that region of the pressure belt which is in heating contact with the drum is in communication with a vacuum or is under atmospheric pressure.
