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) temperature. 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 instructions and the time, temperature and pressure readings necessary for operating the apparatus (10) in the language of choice.
A manually operated apparatus for thermally bonding indicia to fabric having relatively movable upper and lower platens with a heat source in one of the platens for heating it and mechanism for urging the platens together and for varying the pressure therebetween;
In apparatus for thermally bonding indicia to fabric having relatively movable upper and lower platens, the upper platen being carried by an arm, with a heat source in one of the platens for heating it and manually operable over-center mechanical locking mechanism for urging the platens together;
In apparatus for thermally bonding indicia to fabric having upper and lower platens one of which is manually movable between open and closed positions relative to the other;
In apparatus for thermally bonding indicia to fabric having upper and lower platens, the upper platen being manually pivotable to travel in both vertical and horizontal planes between open and closed positions relative to the lower platen;
In apparatus for thermally bonding indicia to fabric having upper and lower platens, the upper platen being manually movable between open and closed positions relative to the lower platen;
