Abstract
A film folding control apparatus of a wrapping machine is a type in which a length of film fed by a film feeding mechanism is extended at a predetermined section of the wrapping machine. An article to be wrapped is raised into taut engagement with the extended film from therebelow. The edges of the film are folded under the bottom of the article, thereby wrapping the article in the film, by a film folding mechanism comprising left, right and front folding plates. The control apparatus comprises a data setting device for setting film length data, film tension data and tray type data in dependence upon a number of an article to be wrapped. A preset memory stores this data in correspondence with the number of the article to be wrapped. A control unit is responsive to an input of the number of the article to be wrapped. The control unit reads the corresponding film length data, film tension data and tray type data out of the preset memory and controls, on the basis of the read data, the operating timing of such operating sections of the wrapping machine as the left, right and front folding plates and grippers for grasping both edges of the film.
