Abstract: Arrangement for cutting notches in box blanks fed along a feeding direction. A feeding portion feeds box blanks. At least a first-fourth cutting devices along the feeding direction. The first is arranged most upstream and the fourth is arranged most downstream. Each device includes: a first wheel rotating around a first axis transverse to the feeding direction, the first wheel being on a first side of the blanks; a second wheel rotating around a second axis extending transverse to the feeding direction parallel to the first axis, the second wheel being in the same plane as the first wheel on an opposite side of the blank; and a cutting element cutting notches. The cutting element extends from either the first or the second wheel towards the other. A control unit controls the operation of the first-fourth devices for different operation combinations.
