Abstract
A thermal stamping apparatus wherein the speed at which a heat transfer roll traverses the surface of an object can be varied in response to changes in the surface temperature of the transfer roll.
Claims3
A thermal stamping device for transferring a film from its carrier to the surface of an object to which said film is to be adhered, said device comprising:
- a heat transfer roll for pressing said film and its carrier toward said surface as said transfer roll rolls over said surface;
- a heater for heating said transfer roll;
- a temperature control means for controlling said heater;
- drive means for rotatably supporting said object adjacent said transfer roll, said drive means including speed control means for controlling the stamping speed at which said transfer roll traverses said surface;
- and,
- speed modifying means for controlling said speed control means to vary said stamping speed in accordance with variations in the surface temperature of said transfer roll.
