ABSTRACT OF THE DISCLOSURE An enveloper system is disclosed which fabricates envelopes around a series of continuously moving single or multiple page letters. Very accurate registration or synchronization of the envelope web blank and letter at high speed is achieved by supplying envelope blanks from two separate stacks of envelope blanks to a pair of Bernoulli plates from which the blanks are fed alternately to continuously running take-away rollers. The accuracy of registration or synchronization is achieved by the fact that the alternate feeding takes place initially at only half the speed at which the letters are moving through the system.
