An improved apparatus (10) for thermally bonding indicia to fabric disclosed comprises relatively movable upper and lower platens (12,14) with a heat source in one of the platens for heating it. A lift lever (18) with an over-center locking assembly (20) is operated to urge the platens (12,14) together and a pressure adjustment assembly (40) is adjustable for varying the pressure therebetween. A pressure sensor (54) senses pressure between the platens (12,14) during closure. A temperature sensor (69) responds to the temperature of the heated platen (12) for controlling heat source (16) to regulate the platen (12) tempera- ture. An optical switch (70) is responsive to platen (12,14) closure for initiating a timing sequence. A programmable controller (48) is programmable to monitor sets of temperature, pressure and platen closure combinations and a visual display (46) displays instruc- tions and the time, temperature and pressure readings necessary for operating the apparatus (10) in the language of choice.
