Abstract
A manually fed folding machine comprising a horizontally reciprocal fold plate for making a first fold in an article, a pivotally movable fold bar clamps the leading edge of the article while the first fold is made and then unclamps the leading edge and carries it about a second predetermined fold line and into superposed relation with the first fold line. A vertically reciprocable fold knife is pivotally connected to spring-clip clamps and the vertically reciprocable fold knife is elevated to move the clamps into clamping position against the article during the second fold and the fold knife is then lowered against the article to impart a third fold while simultaneously lifting the clamps from the article.
