  • Apparatus for transferring paper napkins or similar products from the production machine to stacker means
    Patent number: 5356131
    Abstract: The apparatus for transferring individual articles (M) in sheet form and placing them in stacks (P1, P2) of pre-determined numbers includes a conveyor (17, 23) which picks up the articles from a delivery system (11) by gripping them along their edges. Along said conveyor at least two reciprocating expellers (27, 29) disposed in series remove said articles from the conveyor and lay them down onto a stacker device (31, 35; 33, 37). Each expeller (27, 29) operates with continuous, reciprocating motion at all times. The expeller (27) which is closest to the delivery system (11) may selectively be moved, in the direction of its reciprocating motion, so as to take a position (27X, 27Y) in the trajectory of the manufactured articles fed by said conveyor means, and, alternately, a position (27X', 27Y'), in which it is not in the article-feeding trajectory.
