Abstract: A self-mailer machine for producing self-adhered mailers from single sheets has improved vacuum feed for high operating speed and larger batch loading than has been previously available. The machine also has an improved glue reservoir system wherein glue is provided in sealed containers to be punctured at the time of loading the glue to the reservoir. Optional features are a forms compactor to keep glued forms together until glue sets, and a rotator/perforator for rotating forms at high speed to perforate lines at a right angle to previously perforated lines.
