Claims

[Claims for Utility Model Registration] A presser roller row 4 consisting of a plurality of upper and lower pairs of presser rollers 3n facing or in contact with each other on a reference plane 5 through which the cardboard P to be formed passes, and an outer side of the presser roller row. a guide rail 6 that extends in the traveling direction of the cardboard along the reference plane and includes a table surface that slides and supports an inner portion of the folding line position of the end of the cardboard that passes through the reference plane; and a table of the guide rail. It consists of a plurality of folding rollers 7n that indirectly abut against the free end of the table from above the cardboard passing above, and each of the folding rollers roughly has a flange portion 7na and a flange portion 7na. , and a truncated conical drum part 7nb coaxially connected to the flange part at the bottom, and the arrangement of the plurality of folding rollers with respect to the free end of the table is such that the arrangement of the plurality of folding rollers with respect to the free end of the table is such that The angle α formed by the slope of the truncated conical drum portion with respect to the plane of each of the flange portions gradually changes from an obtuse angle to an acute angle.
