Abstract
A wrapping machine of the present invention comprises a wrapping portion for wrapping a material, a film feeder for feeding a wrapping material (film) to the wrapping portion from a film roller, a material feeder for feeding the material to the wrapping portion, a film folding device for wrapping the material with the film at the wrapping portion, and a material transfer device for transferring the wrapped material. When a material is placed on a conveyer of the material feeder, the material abuts on a stopper to temporarily stop, and then is transferred to a lift of the material feeder. The width and length of the material are detected during the transfer. The lift then moves upward to supply the material to the wrapping portion. The film drawn from the film roller by the film feeder is supplied to the wrapping portion where the material abuts on the film from below so that the upper portion of the material is covered with the film. The film is then folded under the material by the film folding device. The material is wrapped and then transferred by the material transfer device.
