摘要：

A method of and apparatus for folding carton flaps is provided which uses a folding rail having entry (114), transitional (116) and exit (118) sections that include vertical (120), curvilinear (134) and horizontal (124) surfaces, respectively. The curvilinear surface (134) has a curvature developed from three-dimensional modelling on a computer aided design system to consistently square the cartons. A leading folding rail (20) is mounted on a stationary mounting block (16) and a trailing folding rail (22) is mounted on a translatable mounting block (18) so that the folding rails may accommodate different width cartons. The folding rails have guide rails to guide the folded cartons into a compression finger assembly (28) where easily replaceable TeflonTM rails (154) compress the flaps to spread the glue. A transport rail assembly of TeflonTM rails follows to provide a smooth, nonabrasive surface for the cartons to slide along as the cartons set.
