A machine for automatically setting up boxes, having a frame which supports a bed and a magazine above the bed for holding box blanks. A pneumatic system draws the blanks one at a time down to the bed, and a plurality of plates sequentially fold the various blank walls and flaps into position.

Below a stack of blanks in a receiving frame is arranged an upwardly and downwardly movable piston which engages and sucks in the bottom forming portion of the lowermost blank and moves it downwardly past stationary guide members which fold the side wall forming portions and cover upwardly. A control piston actuates pivotally mounted grippers which enter into corner slots at the bottom forming portion of the blank and clamp the bottom of the box against the suction piston during its downward mov...

An apparatus for removing folding box blanks from a folding box magazine and transferring them to between drivers of a conveyor system has a suction rotor with suction cups. The suction rotor is coupled to a four-bar mechanism, which erects the folding box blank along a stationary erecting shunt. By the engagement of the suction cups with a trailing side wall of the folding box blank, which wall stands vertically with reference to the feeding direction, and because of the disposition of the erec...

A long seam gluer for folding a carton blank into cylindrical form and forming a glued seam between the outer surface of a glue flap and a glued area on an overlying side panel includes a magazine for holding a stack of carton blanks, feed mechanism for feeding carton blanks one at a time from the magazine in a predetermined direction with a longitudinal extent of the glue flap in the side panel normal to the predetermined direction, first folding mechanism for folding a first portion of the car...

A preferred embodiment of the invention comprises a box forming machine operable to raise folded box material to a box frame, and to fold the edges that comprise the box bottom into a bottom area and to tape the folded edges. The forming equipment is equipped with a box material supply that stores folded box stock material. The apparatus withdraws a piece of box material from the box material supply station by means of a vacuum chuck. The box stock material is raised to a box frame by means of a...

An apparatus is disclosed for forming planar sheets into containers for containing a flowable food or like product. The container-forming apparatus has an apparatus frame with a plurality of treating stations including a planar sheet feed station. The apparatus also has a rotary body having radial mandrels which are rotatable so as to stop at each of the plurality of treating stations. A holding device is provided on each of the mandrels for holding the planar sheets to the mandrel, and a feeder...

Flat carton blanks having front and rear pairs of side panels, each panel having an associated top and bottom flap, are stored on edge in a magazine. The endmost blank is fed from the magazine in its own plane to a folding station, thence to an erection station, and finally through a gluing station to a compression station. The folding station has upper and lower pivoted plows for folding the top and bottom flaps respectively to the same side of the plane defined by the flat carton blank. Certai...

In the method for feeding blanks in the container-forming unit, the blank is advanced onto the wrapping mandrel which is attached to a moving structure, which moves the wrapping mandrel between the different processing stations of the container-forming unit. Blanks are advanced as a continuous blank web to the wrapping mandrel of the wrapping station, where they are detached from the end of the blank web and advanced onto the wrapping mandrel. The blank web is fed by means of a conveyor situated...

A method and apparatus for squaring knocked down slotted boxes employs an L-shaped support and forming platform onto which a partially opened box is applied so that the junction of the two legs of the L-shape is received within the box and a leading flap (and its fold line connection to the box) and a trailing flap (and its fold line connection to the box) each contact one of the legs to fold these flaps outward and tend to square the box. The trailing flap is moved from one leg onto the other w...

A machine for forming cardboard boxes of the double-plinth type provides for the supply to the machine of flat punched sheets, already partially glued, intended to constitute the bottom, the side walls and the hinged lid with a first attached plinth of the box, in parallel with the supply of auxiliary punched sheets for defining, after gluing to the bottom of the box, the second plinth of the box itself. The machine forms the box and automatically glues the auxiliary punched sheets to the box it...
