The lower straightening appliances (2) consists of an endless belt (52) driven and supported by the rollers (54) arranged on the axis of the rollers (36) of the pivoting levers (17). The shifting motion of the supports (16) on the horizontal plane results in the aligning of the box blanks along a lengthwise aligning rail. The present device is usable on folder-gluers designed for manufacturing folding boxes.
