The present disclosure relates to an apparatus (100) or a reusable dispenser adaptable for mounting coreless stretch film (106) comprising a hollow cylindrical body (101) with at least one elongated slit (102) along the length of the cylindrical body wherein, the body has a right portion (107a) and a left portion (107b), and an outer wall (104) in which at least one of the left or right portion (107a, 107b) is compressed for slotting into an opening of the film roll (106), such that the outer wall (104) mounts firmly onto inner wall (105) of the opening for grasping the surface of inner sheet of the film roll during dispensing.

A plastic film roll includes: a convolute cardboard tube including a tubular body having a tubular body wall formed by a plurality of layers of a straight rolled cardboard sheet having a weight equal to or less than 300 gsm; a plastic film wound about the convolute cardboard tube to form a plurality of plastic film windings around the convolute cardboard tube, the plastic film windings creating a radial compression force equal to or greater than 10 bar on the tubular body wall, wherein the cardboard sheet includes a plurality of fibers, at least a majority of the fibers being substantially aligned in a tangential direction relative to the tubular body to allow the convolute cardboard tube to resist the radial compression force.

A cord containment adaptor can be adaptively anchored or fixed to or removed from an earphone cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that may have multiple earphone cord entrapment chambers and/or an offset or non-linear path leading to an earphone cord entrapment chamber or chambers to help anchor the cord containment adaptor on the cord segment to prevent inadvertent dislodgement of the cord containment adaptor from the earphones. The structure of the anchor slot can be rigid and serves to firmly grip or compress earphone cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. Entrapment chambers of the anchor slot are connected to every other entrapment chamber via cord passageways through which an earphone cord segment can pass. The cord containment adaptor may contain cord containment slots separate from the anchor slot. When a cord containment adaptor is anchored via the anchor slot, earphone cord segments can be gripped into slots in a manner that contains loose cord ends and helps prevent tangling of earphone cords when the earphones are stored or not in use. The adaptor can remain fixed to an earphone cord segment during audio listening by a user and during storage of an earphone set.

The present disclosure is directed to a reusable yarn carrier tube around which yarn may be wound at high speeds (e.g., within winding machines). The yarn carrier tube may include a pick-up groove having structural features configured to better snag yarn to initiate winding of the yarn around the cylindrical body of the yarn carrier tube. The structural features may include an adaptable snagging feature that is adaptable to many different yarn types (e.g., diameter, denier, texture, material). The structural features may include projections (e.g., teeth) with incremental narrowing therebetween in the direction opposite to the rotational winding direction. The teeth may increase in sharpness (e.g., decreasing radii of curvature) as the yarn moves further into the pick-up groove.

The present disclosure relates to an apparatus for accommodating copper foil. The apparatus includes an accommodation body having an accommodation space which accommodates copper foil wound on a core, a support portion coupled to the accommodation body and configured to support both ends of the core, and an elastic member disposed between the support portion and the core and configured to support the core. Here, the elastic member includes a body portion, a plurality of first protrusions arranged on a top surface of the body portion and extending in a longitudinal direction of the core, and a plurality of second protrusions arranged on a bottom surface of the body portion and extending in a direction perpendicular to the extending direction of the plurality of first protrusions. Accordingly, vibrations may be buffered in a frequency band of vibrations occurring in a transportation process.

Rolls of battery separator material and related methods are disclosed. A roll of battery separator material includes a core including an outside surface, a separator material rolled around the core, and a friction enhancing surface on at least a portion of the outside surface of the core to prevent the separator material from lateral migration relative to the outside surface of the core.

A packaged film for masking an aircraft component, wherein the packaged film is configured to form a tubular sleeve when unpackaged. The packaged film is formed by performing a longitudinal telescopic folding operation on a longitudinal portion of a film to provide a longitudinally parallelogram-shaped stacked film; and performing at least a first transverse folding operation on a first portion of the longitudinally parallelogram-shaped stacked film, the first transverse folding operation comprising an operation selected from accordion folding and roll folding to provide the packaged film. The packaged film is capable of being unfolded in a reverse order of the longitudinal telescopic folding operation and the first transverse folding operation to cover said aircraft component.

Provided are an adhesive tape pasting device, mechanism and method for zero-tension double-faced adhesive tape pasting, which belong to foil adhesive tape pasting apparatuses. The adhesive tape pasting device comprises an unwinding station, a winding station, a winding electric motor and an adhesive tape pasting assembly, where after the unwinding station unwinds a double-faced adhesive tape and the adhesive tape pasting assembly pastes an adhesive tape of the double-faced adhesive tape onto a foil, the winding electric motor drives the winding station to wind a remaining release paper of the double-faced adhesive tape. The adhesive tape pasting device further comprises an unwinding driving assembly, where the unwinding driving assembly drives the unwinding station to carry out unwinding work, and in the adhesive tape pasting process, the unwinding work and winding work are carried out synchronously.
