Abstract
A print pad has a nearly spherical tip section having a first radius. A partially spherical first midsection is behind the tip section, the first midsection having a radius less that the radius of the tip section. A frustoconical second midsection is behind the first midsection. A bell shaped third midsection is behind the second midsection, and a frustoconical base is behind the third midsection.
Claims4
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.
