ABSTRACT:
A machine and method for making a strip of dome arrays on a backup strip, wherein the dome arrays include a plurality of domes in a predetermined non-linear pattern and in oriented relation to each other that are adhesively mounted on a dome seal. The machine comprises a punch press or stamping machine capable of simultaneously stamping a pattern of domes in non-linear arrangement and oriented relative to each other and depositing those domes onto the adhesive side of a dome seal strip. The machine also includes means for feeding dome seals to the stamping machine and also for kiss-cutting the dome seal while on the backup strip to define a plurality of successively arranged dome arrays.
