Abstract: A rotating tucking device for securing a wrapper to a roll in a roll packaging system comprises a tucking arm for insertion into a hollow cavity of a roll and a rotating insertion system connected to the tucking arm for moving the tucking arm in a rotational pattern coordinated with the movement of the roll through the roll packaging system such that the tucking arm and the rotating insertion system tuck a wrapper into the hollow cavity of the roll as the roll moves continuously through the roll packaging system. Also provided is a roll packaging system having a rotating tucking device, as well as a rotating tucking method for securing a wrapper to a roll as the roll moves continuously through the roll packaging system.

Abstract: The invention relates to a packaging machine for inserting articles which are prepackaged in bags, into folding boxes in an insertion area. The bags can be inserted via an opening cross-section of the box which is able to be at least partially covered by an essentially flat top flap. A device having a receiving area for a top flap of a box is provided in the insertion area. The top flap is, in the insertion area, positioned in the receiving area and is kept in a convex shape so that, at least during the insertion of the bag and of the box when the top flap is convexly shaped, the opening cross-section of the box is larger than when the top flap is flat.

Abstract: A packaging machine having a folding apparatus for closing an end of an end loaded carton that includes leading and trailing side end flaps. The packaging machine includes a carton conveyor for transporting a carton in a flow direction along a carton path. The folding apparatus includes a lug assembly that has at least one folding lug that travels along an endless lug path. The folding lug travels in the flow direction and in parallel to the carton path along at least a portion of the lug path such that the folding lug can operate in concert with separation guide and a combination guide to fold the leading and trailing side end flaps in the desired sequence.

Abstract: A method and machine for wrapping an article, whereby the article is fed through a feed station, where the article is applied with a respective sheet of wrapping material which is folded into an L about the article, so as to have a free edge not contacting the article, and through a follow-up wrapping station, where the sheet of wrapping material is folded about the article to form a tubular wrapping by applying the free edge onto the article; between the feed station and the wrapping station, the free edge of the L-folded sheet of wrapping material is subjected to traction in substantially the opposite direction to the travelling direction of the article by subjecting the first free edge to suction, so as to smooth the sheet of wrapping material onto the article.

Abstract: An automatic packaging machine has mandrels with a plurality of fingers for gripping an object. A cam track has contours which defines the location of positions along a conveyor carrying the mandrels. The fingers are closed by a spring and opened by a cam follower encountering a contour of cam track. This way a plurality of objects having a variety of widths may be carried by the fingers without requiring a readjustment of the machine.

Abstract: A container-forming device comprises a container conveyor (21) having a plurality of holders (34) which each include a bottom plate (51) and side plates (52) projecting upwardly from the bottom plate for receiving the container body M1 and intermittently drivable so as to halt the holders (34) at an ear bonding station (S3) in succession, and upper ear pressing member (61) disposed above the ear bonding station (S3) and being moveable upward or downward for pressing upper ears (U1) against an upper wall of a container body (M1), and a pair of lower ear pressing members (62) arranged at opposite sides of the ear bonding station (S3) and being openable or closable for pressing lower ears (L1) against respective side walls of the container body (M1).

Abstract: A flap folding assembly for engaging a work piece, such as a paperboard carton flap, and moving that flap into a desired position. The flap folding apparatus can be used in a continuous motion packaging machine to engage a sleeve type carton flap as the carton is transported downstream through the package machine. The apparatus is operated in timed relationship with the machine's carton conveyor either by mechanically interlinking the apparatus to the main machine drive, or by the use of a servo drive operated from and controlled by the packaging machine's main controller. The flap folding apparatus includes a vacuum cup driven in a circular path by a drive mechanism comprised of two spaced gears which are driven in the same direction of rotation.

Abstract: A unitary panel sorting and packing machine receives vinyl siding panels from an extruded production line. The machine includes a panel receiving section which includes lifting and flipper arms for selectively inverting panels for packing efficiency. From the panel receiving section, the panels are transferred to a panel accumulation section. The machine also includes a box folding section for folding corrugated paper box blanks along predetermined score lines. The box folding section is preferably parallel and adjacent to the panel receiving section and the panel accumulation section and includes retractable arms which selectively position the box in a ready position for packing panels therein. After the box is full, conveyor mechanisms carry the box from the box folding section through a box lid glue applying station and then into a box end folding and gluing station. This machine can substantially reduce repetitive stress caused injury to the operator.
