Stamping apparatus

A stamping apparatus comprising:

• a stamping head;
• a stamping pad;
• the stamping pad being replaceable and impregnated with an ink which is solid at room temperature and becomes workable upon heating;
• heating means for heating the stamping pad to a working temperature of the ink, wherein the heating means includes preheating means in heat conducting relationship with said heating means for storing a replacement disposable stamping pad in heat conducting relationship with said heating means for preheating of the replacement stamping pad.

A stamping apparatus comprising:

• a stamping head;
• a stamping pad;
• the stamping pad being replaceable and impregnated with an ink which is solid at room temperature and becomes workable upon heating;
• heating means for heating the stamping pad to a working temperature of the ink, wherein the heating means includes preheating means in heat conducting relationship with said heating means for storing a replacement disposable stamping pad in heat conducting relationship with said heating means for preheating of the replacement stamping pad.
• wherein said heating means includes a metal casing at least partially enclosing said stamping pad and wherein said preheating means further comprises a chamber for receiving said replacement disposable stamping pad to be heated, and a heating pin being arranged substantially centrally within the chamber and in heat conducting relationship with said metal casing with said heating pin sized to fit inside the replacement disposable stamping pad for heating thereof.

A stamping apparatus comprising:

• a stamping head including a metal type holder;
• a disposable stamping pad impregnated with ink which is solid at room temperature and becomes workable upon heating;
• heating means arranged for heating the stamping pad and being located in the vicinity of a wetting position for the stamping head;
• a displacement mechanism for moving the stamping head between the wetting position in engagement with the stamping pad and a stamping position for engagement with an object to be stamped wherein, in the wetting position, the metal type holder being located within the heating influence of the heating means for the stamping pad and being solely heated thereby while being in wetting contact with the heated stamping pad, whereby the thus heated metal type holder retaining sufficient heat to maintain the wetted ink on the stamping head in stamping condition.

A stamping apparatus comprising:

• a stamping head including a metal text holder;
• a roller shaped stamping pad;
• the stamping pad being replaceable and impregnated with an ink which is solid at room temperature and becomes workable upon heating.
• heating means, formed of a cylindrically shaped metal casing having and enclosing a heating element and surrounding the stamping pad for heating the stamping pad to a working temperature of the ink;
• the metal casing having an opening for allowing passage of the stamping the head;
• a displacement mechanism for moving the stamping head between a wetting position through said opening inside the metal casing and a stamping position for operative wetting engagement with an object to be stamped, wherein, in the wetting position, the metal text holder being located within the heating influence by said heating means and being heated thereby so that the heated metal text holder can retain sufficient heat during its movement between the wetting and stamping positions to maintain the ink in a working condition;
• wherein said stamping pad is mounted for free rotation about an axis and further comprising drive means mounted to said stamping head for rotating the roller shaped stamping pad when said stamping head is away from said wetting position;and
• wherein the drive means comprises a spring pin oriented to resiliently engage the roller-shaped stamping pad at an off-axis location when said stamping head engages the stamping pad, and with the location selected so that upon disengagement of the stamping head from the roller shaped stamping pad, spring action from said spring pin forces a movement of the freely rotating stamping pad.
