A device for inserting an aperture in a film wrapping of a goods stack arranged on a pallet, where the film wrapping is a film hood drawn over the goods stack or as a film sleeve surrounding the goods stack is disclosed.

A piercing element has a rotatably attached actuation arm. The piercing element exhibits first and second part-regions. The first part-region is mounted rotatably on the actuation arm and the second part-region includes the piercing region. The second part-region is pivotable relative to the first part-region from an original position against a restoring force. A corresponding system and a method for inserting an aperture in a part-region of a film wrapping of a goods stack arranged on a pallet is disclosed, where the film wrapping is configured as a film hood drawn over the goods stack or as a film sleeve surrounding the goods stack.

A packaging machine includes a conveying device for advancing a packaging material web at least to a tube forming station at which the web is formed into a tube and for advancing the tube to a tube forming and sealing device to form and longitudinally seal the tube, a tensioning device to control tension of the web and/or of the tube and a control unit to control operation of the packaging machine. The tensioning device has at least one tensioning assembly having at least first and second drive rollers, a first drive motor connected to the first drive roller to rotate the first drive roller and a second drive motor connected to the second drive roller to rotate the second drive roller. The control unit controls the first and second drive motors such that a free loop of the web expands and/or advances between the first and second drive rollers.

A carriage for a stretch wrap assembly including a base, a top housing, and a pre-stretch assembly. A bottom portion of the film is formed into a roped or creased portion between an area wherein the film leaves a roll of stretch wrap and the pre-stretch assembly.

Dispenser with bearings for dispensing a roll of tension activated expandable sheet material, as well as methods for using the same.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.

A handling device having a holder for gripping web-shaped packaging material, which holder has a curvature in the longitudinal direction of the holder. When the packaging material is gripped by the handling device, a free end section of the packaging material is arched in the transverse direction of the packaging material and projects out from the handling device to be inserted into a processing station of a packaging machine.

A tension-inducing shaft system includes a shaft, two shaft caps, and a biasing mechanism. A bore extends through the shaft between two ends of the shaft. The shaft caps are positioned on the two ends of the shaft. Each shaft cap includes a collar having a size that is larger than the bore, a keyed end, and an anchor. The biasing mechanism is arranged inside the bore and is coupled to the anchors of the shaft caps so that the biasing mechanism exerts inward forces on the shaft cap. The keyed ends of the shaft caps can be coupled to a housing so that the shaft caps do not rotate with respect to the housing. The shaft is configured to rotate with respect to the shaft caps such that, when the keyed ends are coupled to the housing, the shaft is capable of rotating with respect to the housing.

A supply roll for a wrap system of a baler implement includes a core having a circumferential wall surface forming a cylindrical shape concentric with a central longitudinal axis. A wrap material includes a length wound about the circumferential wall surface of the core, and defines an exterior circumference. The core and the wrap material cooperate to define a combined center of gravity. An axial position identifier is disposed on the exterior circumference of the wrap material, and is positioned relative to the combined center of gravity to define a desired lift location.

A container cover and dispenser system is disclosed herein. The cover fits over a container and allows a user to access contents through an opening. The cover may include a notch to leave an open section for a user to access the contents. The dispenser may hold a roll of container covers that may be pulled out and individually removed from the roll. The dispenser may include a protrusion to create a tab and notch design on the removed covers to facilitate users' access of the contents.

A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.
