The invention provides an apparatus (26) for forming a box blank from a generally-rectangular sheet of material. The apparatus has a frame (28) for supporting and guiding the sheet; and endless advancement belt (31) for controllably moving the sheet relative to the frame through the apparatus; guide rails (32) extending generally across the sheet; a carriage (34) mounted on the guide rails for horizontal movement relative thereto; a cutting blade (35) mounted for horizontal movement with the carriage and operatively arranged to be rotated about an axis; a blade actuator (36) for selectively causing the blade to have a vertical component of movement relative to the carriage; a punch (38) mounted on the carriage and selectively operable to punch a hole in the sheet; a transverse creasing roller (39) mounted on the carriage; and a pair of adjustable longitudinal creasing rollers (40) mounted on the platform. As the sheet is moved relative to the frame, the transverse creasing roller may selectively crease the sheet in a transverse direction, the longitudinal creasing rollers may selectively crease the sheet in a longitudinal direction, and the cutting blade may selectively cut slots from both longitudinal edges.

An apparatus for forming a scored and slotted box blank from a generally rectangular sheet of material, comprising: a frame for supporting and guiding said sheet; advancement means for controllably moving said sheet relative to said frame through said apparatus along a longitudinal sheet travel direction; guide means extending generally transverse to said longitudinal sheet travel direction; a carriage mounted on said guide means for transverse movement along said guide means; transverse slot cutting means mounted on said carriage for transverse movement with said carriage to transversely cut and form respective slots in said sheet, each slot having a slot root; cutting actuator means mounted to said carriage for selectively causing said transverse slot cutting means to have a vertical component of movement relative to said carriage and said sheet; punch means mounted to said carriage for selectively punching holes at said slot roots; punch actuator means mounted to said carriage for selectively causing said punch means to have a vertical component of movement relative to said carriage and said sheet; a transverse creasing roller mounted on said carriage adapted to selectively engage and transversely crease said sheet at selected locations; and at least one longitudinal creasing roller means mounted on said guide means adapted to selectively engage and longitudinally crease said sheet at selected locations; whereby, as said sheet is moved relative to said frame, said transverse creasing roller selectively creases said sheet in a transverse direction, each longitudinal creasing roller selectively creases said sheet in a longitudinal direction, said transverse slot cutting means selectively cuts transverse slots in said sheet from both longitudinal edges and said punch means selectively punches holes at said slot roots.
