A rotating member for a wrap dispenser includes a first portion defining a first outer surface and a first inner surface, the first inner surface defining a first inner diameter; a second portion defining a second inner surface, the second inner surface defining a second inner diameter, wherein the first inner diameter is less than the second inner diameter; and an upset protruding radially outwardly from the first outer surface of the first portion, the upset oriented distal to the second portion, wherein a slot extends longitudinally through the upset to allow the upset to flex radially inward.

A sheet dispenser system having a roll of sheet material and a housing to receive the roll. The roll of sheet material comprises a first end portion incorporating a key, and the housing comprises a mounting portion arranged to support the first end portion of the roll. The mounting portion comprises a lock arrangement which is movable between a locked condition and a free condition. The lock arrangement comprises a rotatable element configured for rotation about an axis, and a locking element configured for engagement with the rotatable element to inhibit rotation of the rotatable element, such that, when the locking element and the rotatable element are engaged, the lock arrangement occupies the locked condition, and when the locking element and the rotatable element are disengaged, the lock arrangement occupies the free condition. The mounting portion is arranged such that the roll is movable between an engaged condition, in which the key engages the mounting portion, and a disengaged condition, in which the key is disengaged from the mounting portion, such that, when the roll is moved from the disengaged to the engaged condition, the first end portion of the roll moves the lock arrangement into the free condition, thereby permitting rotation of the rotatable element. The locking element and the rotatable element are configured for engagement by relative movement of the locking element and the rotatable element towards each other in a direction along the axis of rotation of the rotatable element.

There is provided a film dispenser including a pre-stretch assembly, a dancer bar and a dancer bar control assembly. In response to a variation of a film feed requirement, the dancer bar is movable over a displacement range between a first position and at least one second position. The dancer bar is in the first position when a tension in the material web is below a threshold and in the at least one second position when the tension in the material web is equal to or above the threshold. The dancer bar control assembly is connected to the pre-stretch assembly and the dancer bar and is configured to bias the dancer bar with a constant force over the displacement range, monitor a displacement of the dancer bar and generate a speed command based thereon, and send the speed command to a motor to adjust the film delivery speed.

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 the 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.

An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.

A method for providing rolls of material for use in sheet form, particularly aluminum for food uses, comprising a step of rewinding the material for use in sheet form in order to form a roll; the rewinding step is provided by winding the material for use in sheet form directly on a rewinding shaft, with the material for use in sheet form in contact with a cylindrical outer lateral surface of the rewinding shaft, which is actuated with a rotary motion about its longitudinal axis, so as to obtain a coreless roll.

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.

Disclosed herein are protective packaging stock material units that are used in a dunnage system. A dunnage system includes a dunnage conversion machine and a supply station. The supply station is a cart that includes a biased support that is connected to a vertical side support. The biased support is movable from an open position to a closed position with respect to opposing vertical side supports. In the closed position, the biased support is configured to at least partially block the opening between the opposing vertical side supports. In the open position, the biased support leaves the opening between the opposing vertical side supports sufficiently open to load fanfold stock material therein. The biased support is biased towards the closed position and the open position. The supply station also includes an alignment device forming a funnel positioned under its base. The alignment device receives a dunnage machine stand base causing the supply cart to consistently align with the stand base in response to the stand base being slid into engagement with the alignment device.

A film dispenser includes a holding member and a rotating member, the holding member including a first end including a handle, the handle including a plurality of lobes and a plurality of web portions, each web portion extending between a pair of adjacent lobes of the plurality of lobes; and a second end defining a brake portion defined by a slot, the holding member defining a longitudinal axis that extends from the first end to the second end, the slot including a first portion extending in a circumferential direction across a full width of the brake portion and two opposing portions extending at an angle from the first portion; each of the plurality of web portions extending outward beyond an outermost edge of the rotating member relative to the longitudinal axis.

A film dispenser for dispensing stretch wrap or other flexible materials. The film dispenser is comprised of paper or cardboard. The film dispenser being inserted into an extended core or having the extended core inserted into the film dispenser.
