<p>An improved apparatus (10) for thermally bonding indicia to caps comprises relatively movable upper and lower platens (12, 14) with a heat source in one of the platens for heating it. A handle (18) pivotal in a vertical plane raises and lowers the upper platen (12) swinging it through virtually a 90 DEG arc to permit easy positioning of a cap between the platens where they are open. Both platens (12, 14) have curved nesting pressing surfaces (20, 20'), the upper platen pressing surface (20) having a concave shape and the lower platen pressing surface (20') having a convex shape with the radius of curvature of the upper platen pressing surface (20) being greater than the radius of curvature of the lower platen pressing surface (20') so that the platens (12, 14) apply equal pressure across a cap disposed between them. Apparatus (10) further includes a keypad (40) and digital readout screen on the handle for ready viewing and access by the operator and further includes a microprocessor controller for regulating temperature of the heat source and time of the heat cycle.</p> |
