Abstract:
1. A lamination apparatus, comprising: a frame including a base; a linear motion device attached to the frame opposite the base; a ram coupled to an end of the linear motion device, the ram including at least one air passage that provides an air evacuation path when the ram is working on a workpiece; a first elastomer attached to the ram attached only to a central portion of the ram, wherein the first elastomer functions as a plunger; a second elastomer attached to the ram, wherein the second elastomer contacts and covers the first elastomer such that an air gap is formed between the ram and second elastomer, and wherein the second elastomer has a convex outer surface; and wherein compressed air located between the ram and the second elastomer escapes though the evacuation path when the linear motion device is in an extended state.
