An ambient batch-processing loader (no total count, only continuous throughput) built as a letter-facing and cancelling machine's orientation stage: mixed-orientation envelopes travel a single-file lane, a fixed gate reads each one's stamp corner, and any envelope not already stamp-corner-up-right rotates into that orientation as it crosses, picking up a brief tap of ink as it continues.
