A paper board blank is formed into a tray having a double glued side wall construction for providing a desirable strength to the tray. A platen drives the blank through forming rails which fold the blank into a partially formed tray having bottom, end and side walls, and inside corner supports formed about the platen. After the platen is retracted, a first folding arm folds a top wall portion to a position generally parallel to the bottom panel. A second folding arm then folds end fold portions ...

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 station includes a magazine containing stacks of flat folded tubular blanks arranged horizontal. Each stack is supported by openable support pad pairs. A platform moves vertically below the magazine and receives, when set at a raised loading position, one stack released by opening a lowermost pad pair. The platform is subsequently lowered, together with the stack, to a waiting position. A withdrawing arm, mounted on a slide moving horizontally, has suction cups for picking up a blank from the ...

A machine for forming and gluing a three-part container having two wall panels and a body panel forming the bottom and the other two walls of the container. The body panel is sealed to the wall panels by flanges which are attached to the bottom and walls of the body panel, and which bend over and are contiguous with the faces of the wall panels. The apparatus carries the body panel into position between a mandrel and a die, and positions the wall panels with respect to the body panel. The mandre...

A slide loader is mounted over a vertical projection gate open at the top thereof. The slide loader includes supply and takeup magazines for supporting slides in face-to-face contact. A pair of members engage edge portions of the foremost slide in the supply magazine for rocking such slide to separate the same from the adjacent slide and to orient such foremost slide with a discharge opening at the outlet end of the supply magazine. A shiftable plate receives the foremost slide after it passes t...

A machine for forming cartons from pre-cut and pre-scored blanks comprising a carton blank storage and first feed subassembly for feeding blanks linearly from a stack thereof and which is adjustable to accommodate blanks of different lengths, widths and thicknesses; a second feed sub-assembly for accepting the blanks and including a pair of endless travelling belts for feeding the carton blanks linearly; a flap bending and glue or hot melt applicator subassembly for bending certain of the flaps ...

A machine for forming a precut paperboard blank into carton form with the lid extending vertically from its related back wall in unfolded condition. The forming means includes spring pressed rollers acting in cooperation with a mandrel to fold the carton side panels from horizontal to vertical and other means to cause interlocking of end tabs on the front and back panels with slits in the end panels. The structure also includes vertical slots enabling the unbent end flaps on the lid to pass down...

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...

A substantially rectangular stack of folded wet wipes having an improved dispensability and a method of producing the same are described. The stack of folded wet wipes includes a plurality of wet wipes which are individually folded and arranged in a stacked configuration. Each wet wipe includes a leading end edge which is folded about a fold line. The location of the leading end edge of each wet wipe is selectively varied throughout the stack of wet wipes to provide a more stable stack of wet wi...

In a machine for forming articles of sheet material, an orderly succession of flat blanks is fed along a forming path on a roller conveyor having powered rollers equally spaced with a given spacing; on the roller conveyor, the blanks are maintained contacting the rollers by idle-wheel pressure devices, and are deformed by folding devices; the pressure devices and folding devices being fitted to respective gantry-type frames having respective removable cross members, and which can be set to a num...
