Abstract
A machine for automatically applying stamps onto successive envelopes at a precise location and without distorting or marring the stamps or envelopes comprises vacuum devices for picking off the stamps and envelopes from respective magazines, feeding each envelope into an exact position below a backing pad, and concurrently feeding a respective stamp past a moistening device into an exact position below the envelope, then pressing the envelope against the backing pad and concurrently pressing the stamp upwardly against the envelope, and thereupon releasing the vacuum devices and knocking out the stamped envelope into a receptacle as the machine is returned to a start position for another application cycle.
Claims8
A machine for automatically applying stamps to envelopes comprising respective magazines for said stamps and envelopes mounted in parallel arrangement, respective vacuum pads for picking off said stamps and envelopes one by one from the same ends of said respective magazines, a main carriage for said vacuum pads mounted for back and forth shifting movement in the directions of said magazines, means yieldably mounting said pads on said main carriage for independent movement relative to the carriage in directions of said shifting movement, means mounting said respective pads on said carriage for traveling movement at right angles to the carriage movement to and from a stamping station whereat a stamp from the stamp magazine is placed in overlapping relation to an envelope from the envelope magazine, and power means cyclically operable for imparting a first reciprocation to said main carriage towards and from said magazines to cause said pads to pick off a stamp and an envelope from the respective magazines, to impart then a traveling movement to each of said pads to said stamping station, and to impart next a second reciprocation to said carriage in the directions of said shifting movement to cause said stamp to be pressed against said envelope.
