Abstract
Transfer apparatus and method are provided from first (15A, 16A) to second (15B, 16B) stations of tooling in a cap (11) making press. This cap is biased against the first upper tools by a first airstream (50) introduced under the cap and moves upward with the first station punch (45). As the punch approaches its top location, a transfer airstream (52) begins while the first airstream is still on, and moves the cap out through a transfer chute (18) to the second station. The cap departs the chute and passes detents (67) on a pair of closed retention fingers (60) which define an extension of the transfer path from the chute into the open second station tools. A vacuum (85) applied to a port in the second station punch then holds the cup against the rising upper tools. When the punch clears the closing fingers and approaches its top location, an ejection airstream (87) commences to propel the finished cup via a discharge chute (19).
