Abstract
An apparatus wherein a hot stamp transfer roller can be quickly removed from the metal core after the hot stamp transfer roller is used up and immediately replaced with another hot stamp transfer roller so that the process can continue without having to return the central hub and the remaining portion of the hot stamp transfer roller to a facility where the hot stamp transfer roller is ground away from the central hub.
Claims12
A hot stamp transfer roller assembly comprising:
- a. a central hub including a body with an upper surface having a central opening and including a multiplicity of attachment receiving members at spaced apart locations on and extending from the upper surface into the central hub, a bottom plate, an exterior circumference including a multiplicity of mating interlocking members extending around at least a portion of an exterior circumference of the central hub and affixed to the bottom plate;
- b. a replaceable hot stamp transfer roller having an exterior circumferential surface retaining hot stamp transfer foil thereon, the hot stamp transfer roller including a central opening surrounded by an interior circumferential surface which includes a multiplicity of mating interlocking members extending around at least a portion of the interior circumferential surface;
- c. a cover plate having a body with a central opening aligned with the central openings in the hot stamp transfer roller and the central hub, the cover plate including a multiplicity of openings aligned with the multiplicity of attachment receiving members in the central hub, a multiplicity of attachment members, with a respective one of the multiplicity of attachment members extending through a respective one of the multiplicity of openings in the cover plate and extending into and affixed into a respective one of the multiplicity of attachment receiving members in the central hub aligned with the respective one opening the cover plate;
- d. the multiplicity of mating interlocking members of the removable hot stamp transfer roller removably interlocked with the multiplicity of mating interlocking members of the central hub;
- and
- e. the cover plate removably affixed to the central hub to sandwich the removable hot stamp transfer roller between the cover plate and the plate of the central hub, the cover plate covering the mating interlocking members of the hot stamp roller and the central hub.

An apparatus comprising:
- a. a central hub having a bottom fixed plate and an extending cylindrical section affixed to the bottom fixed plate, the extending cylindrical section including a multiplicity of spaced apart tongue and groove members extending around an exterior circumference of the cylindrical section with a respective groove adjacent opposite sides of each respective tongue and a center area including a multiplicity of threaded mating members, and a central opening;
- b. a removable hot stamp transfer roller containing a multiplicity of tongue-and-groove members on an interior circumferential surface, a respective tongue of the central hub aligns with a respective groove of the hot stamp transfer roller and a groove in the central hub aligns with a respective interior facing tongue of the hot stamp transfer roller to removably engage and retain the central hub and hot stamp transfer roller together;
- and
- c. a cover plate having a multiplicity of openings, a respective threaded bolt inserted through a respective opening in the cover plate and threaded into a respective aligned threaded opening in the central hub so that the cover plate serves to retain the hot stamp transfer roller to the center hub, the hot stamp transfer roller removably affixed to the central hub to facilitate replacement of a used hot stamp transfer roller by removing the cover plate, disengaging the tongue-and-groove members of the central hub and the hot stamp transfer roller and replacing the used hot stamp transfer roller with a new hot stamp transfer roller having mating tongue-and-groove members which mate with respective tongue-and-groove members of the central hub.
