ABSTRACT:
A machine for wrapping an article with a belt-like wrapping material of film, synthetic resin laminate or the like, includes a folding and opening unit having a length about a half of the wrapping material. The unit comprises an inverting guide, a raising guide, and a folding guide. The inverting guide has a straight inverting and guiding section transversely crossing the wrapping material at a right angle and a virtually straight slant guiding section connected with one end of the inverting and guiding section and inclined by about 45.degree.. The raising guide is included in a fixed horizontal plane defined by the inverting guide and crosses a meeting point of both guiding sections at a right angle for raising the wrapping material at about a right angle. The folding guide is situated upwardly of a substantially vertical plane which includes the raising guide and has a virtually right-angled equilateral triangle which is located in a plane parallel to the fixed horizontal plane, and has one side extending between an apex on a straight line rising at about 45.degree. with respect to the meeting point and another apex which is right-angled and an inclined side. With this folding and opening unit, the wrapping material is folded and inverted longitudinally, and simultaneously the wrapping material is opened in U-shape cross section to receive the article. Then the wrapping material with the article is fed horizontally forwardly, and the openings of the folded material are fused and cut.
