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.

A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer formed from a fluorine resin, a substrate layer, an adhesive layer, and a release liner formed from polyethylene terephthalate (PET) in this order in a laminating direction. The process film is formed from at least of polyethylene terephthalate (PET), polyolefin, and polyvinyl chloride (PVC), and is thinner than the release liner.

A dunnage conversion apparatus for dispensing a cushioning wrap material from a roll of expandable slit sheet material is described. The roll of expandable slit sheet material includes an expandable slit sheet material in an unexpanded state. The expandable slit sheet material is pulled from the roll of expandable slit sheet material and expanded to a pre-expanded state and an expanded state. To expand the expandable slit sheet material and form the cushioning wrap material, a stretching force is applied to the expandable slit sheet material in a stretching direction as it is pulled from the roll of expandable slit sheet material. Accordingly, the dunnage conversion apparatus includes a tensioning device for assisting in the application of such stretching force.

A feed device includes: a feed tray configured to accommodate a roll, in which a medium is rolled in a roll shape, rotatably; a housing configured to support the feed tray installable; and a pull-back mechanism configured to pull back the medium unrolled from the roll in a direction orthogonal to a rotation axis of the roll in conjunction with an outward movement of the feed tray from the housing in the direction orthogonal to the rotation axis of the roll.

An apparatus for winding straps comprises a motor having a shaft extending therefrom to a distal end, the shaft being rotatable thereby along a shaft axis and having a slot extending longitudinally therealong from the distal end. The apparatus further comprises a spool guide located proximate to the distal end of the shaft adapted to retain a strap on the shaft and a strap guide extending parallel to and spaced apart from the shaft axis.

This invention provides a nip roller that has heat resistance and abrasion resistance, wherein a surface of a substantially cylindrical core is provided with a layer of a rubber, the rubber has a change in hardness in a heat aging test at 150 C. for 72 hours according to JIS K6257:2010 which is less than or equal to 15 degrees in type A durometer hardness according to JIS K6253:2012, and a surface of the layer of the rubber is provided with a layer of an amorphous carbon coat.

A defect inspection device includes: a radiation source configured to emit an electromagnetic wave radially to a separator roll; a TDI sensor configured to detect the electromagnetic wave which has passed through the separator roll; and a moving mechanism configured to move an inspection region of the separator roll with a distance kept substantially constant between the radiation source and the separator roll and with a distance kept substantially constant between the radiation source and the TDI sensor.

A packaging container includes an expandable plastic body having a front wall and a back wall, and a top, a bottom, and sides. Each side of the body has a gusset portion extending along a length thereof. Each gusset portion has gusset segments and a pair of adjacent gusset segments are joined along a common fold line. Each gusset segment has an inner surface and an outer surface. At least one of the gusset segments has an embossed section. The embossed section has a plurality of mounds protruding from one of the inner and outer surfaces and a plurality of depressions corresponding to the mounds within the other of said inner and outer surfaces. A roll for forming a packaging container, and method, are also disclosed.

A method for producing long-term bendable glass material includes: bending a glass material in a bending radius in a range of 1 mm to 10.sup.7 mm; storing the bent glass material for a time period of at least 1 day; inspecting at least a portion of the bent glass material for damage after the storing; and classifying the inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.

A media roll holder assembly a web-based printing system comprises a support for rotatably supporting the roll in an operative position, a holding element for rotatably holding the roll on the support, and a pivotable arm on which the holding element is provided. The pivotable arm is formed and positioned to position the holding element on the roll, such that a lifting force for lifting the roll from the support results in a holding force on the holding element in the first angular direction for holding the roll in the operative position on the support. The roll is then rotatably secured in its operative without excess angular forces acting on the roll. As the rotation of the roll is substantially unimpeded, the medium may be transported with great precision, resulting in high quality printing.
