Abstract:
1. A print pad for printing on a concave surface, with said print pad defining a longitudinal axis, comprising; a longitudinally extended tip section that in axial cross-section defines a pair of complementary converging arcs, with both of said arcs having a first radius R1 that is longer than a distance D1 an inner end of the complementary arcs is spaced from a peak of the printing pad toward which said complementary arcs converge, and with an inner end of the complementary converging arcs being a distance R4 from the longitudinal axis of said print pad, a first midsection behind said tip section, said first midsection diverging outward and away from said tip section and in axial cross-section defining an arc having a second radius R2 less than said first radius R1, with an inner end of the second radius R2 being disposed adjacent to the longitudinal axis of said pad, a frustoconical second midsection behind said first midsection, a third midsection behind said second midsection, said third midsection flaring radially outward of said second midsection and defining a fillet, a frustoconical base behind said third midsection, said frustoconical base diverging rearwardly from an outer circumference of said third midsection, and said tip section, said first, second and third midsections and said base all being symmetrical about the longitudinal axis of said pad.
