Patent ID: 7156020

Claim:
A composite stamp pad comprising; a stamping face portion and an ink reservoir portion, said stamping face portion comprising a first plurality of fibers, said first plurality of fibers comprising low denier bicomponent fibers, said bicomponent fibers being cohesively bonded together and/or to other fibers, contained in said first plurality of fibers, at inter-fiber crossover points, said ink reservoir portion comprising a second plurality of fibers comprising bicomponent fibers, said second plurality of fibers being, on the average, coarser than said bicomponent fibers of said first plurality of fibers by at least 2 denier, said fibers of the second plurality of fibers being bonded together cohesively at interfiber crossover points, said stamping face portion and said ink reservoir portion being joined together at their interface as a two-layer composite structure, thereby providing a stamp pad with a high-capacity ink reservoir and high precision of ink transfer to raised points of a stamp.
