A cutting and opening method for a rectangular package covered with packaging material is provided comprising the following steps: the packaging material of a rectangular package is cut from one edge to the other on two mutually opposing planes after forming a space between the packaging material and the packaged objects; the packaging material on the same two planes is cut from one of the two edges other than those passing the starting point and the end point of these cutting lines to the above mentioned cutting lines; the packaging material is cut on the plane adjacent to the above mentioned two planes and having two edges passing the two cutting lines in such a manner that the two cutting lines are connected after forming a space between the packaging material and the packaged objects; and thereafter, the packaging material is cut open at each area on the three planes where cutting lines are provided. According to a further aspect a cutting and opening device for a rectangular package covered with packaging material comprising: a platform (1), on which a rectangular package is placed, means for forming a space between the packaging material and the packaged objects on the two mutually opposing planes of the package on said platform (1); a pair of cutting blades (3, 3) cutting the packaging material from one edge to the other in the direction of height or width, whereby a space is formed between the packaging material and the packaged objects by said means; a pair of cutting blades (4, 4) cutting said packaging material from one of the two edges other than the edges passing the starting point and the end point of each of the two cutting lines cut by the pair of cutting blades (3, 3) to the above mentioned cutting lines; means for forming a space between the packaging material and the packaged objects on the plane with two edges that pass the ends of the two cutting lines made by the pair of cutting blades (4, 4); a cutting blade (5) for cutting the packaging material so as to connect the two cutting lines on the above plane; and a device for opening the packaging material from each area on the three planes provided with cutting lines. |
