Provided is an adhesive film production apparatus for producing an adhesive film having an adhesive layer on a base material layer, the adhesive film production apparatus including: a feeding roller that continuously feeds a raw film of the adhesive film; a cutting part that cuts the raw film of the adhesive film into a plurality of adhesive films having predetermined widths; and a plurality of winding cores that wind each of the plurality of adhesive films, wherein each of the plurality of winding cores has a width larger than a width of the adhesive film as an object of winding.

Various embodiments of the present disclosure provide a random case sealer. The case sealer includes a top-head-actuating assembly configured to vary the speed of the top-head assembly when ascending (to make room for the case beneath the top-head assembly) and when descending onto the case (to engage the top surface of the case during sealing). This maximizes the speed of the top-head assembly while limiting overshoot (when ascending) and preventing damage to the case (when descending). In certain embodiments the case sealer includes a tape cartridge configured to limit the forces imparted onto the leading and top surfaces of the case during sealing. These features result in increased throughput as compared to prior art random case sealers without requiring stronger cases or more protective dunnage.

A device for dispensing rolled items, such as tape. The hand-held or mounted tape dispensing device is designed to accommodate variously sized or shaped rolls of tape. The tape dispensing device for dispensing a tape may comprise a support structure and one or more tape holder sliders configured to be moveable from a first position to at least one second position. The tape dispensing device may also include one or more tape holder sliders, which may move simultaneously in a single direction. The tape dispensing device may also include a tape dispenser blade having a cutting edge and configured to be moveable from a first position to at least one second position and to rotate to a position along the cutting edge at different angles.

A Support for adhesive tape, including: a cylindrical, or substantially cylindrical, body configured to be inserted inside the tubular core of the adhesive tape; a base, associated with the cylindrical body, to which, in turn, a connecting element to an operator’s garment, or to an operator’s accessory, or to further parts of the operator’s equipment, is associated; at least a retractable element, provided along the lateral surface of said cylindrical body, including a control suitable for selectively actuating said retractable element from a retention configuration of the adhesive tape on the cylindrical body, to a configuration of free removal of the adhesive tape from the cylindrical body, and vice versa.

Provided is a roll body capable of effectively suppressing the occurrence of a telescope phenomenon even if the ambient temperature during transportation and storage of the roll body becomes higher than that during production of the roll body. A roll body RB according to the present invention configured by winding a belt-shaped web around a winding core that thermally expands or contracts due to an influence of a surrounding environment is characterized in that a linear expansion coefficient of the web in a thickness direction is in a range of 60 to 150 times a linear expansion coefficient of the web in a longitudinal direction, and the winding core has a linear expansion coefficient in a range of 20×10.sup.−6/K to 100×10.sup.−6/K and a Young's modulus in a range of 0.2 GPa to 0.5 GPa.

A spool unloading device comprising: a spindle; a first bulk spool of material is mounted on the spindle, wherein the spindle is rotatably controlled to dispense the material; a series of pulleys for receiving the unspooled material such that a variable length of the material is stored within the device before exiting the device to an upstream equipment; and a drive mechanism for indexing the unspooled material exiting the spool unloading machine at a controlled rate.

A binding device binds a material strip reel on which a contact material strip is wound. The binding device includes a frame, a tape supply unit installed on the frame for supplying an adhesive tape, a first damper and a second damper mounted on the frame for clamping the adhesive tape, and a first roller and a second roller installed on the frame. The first roller and the second roller push and paste the adhesive tape between the first damper and the second damper onto a pair of opposite sides of the material strip reel.

Methods and apparatus to form elevated profiles in mounted turn-up transfer tapes for paper processing. In some embodiments, the transfer tape may be a combination of a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and an affixed cord or cordlike feature, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer. In some embodiments an elevated profile, similar to that resulting from the incorporated cord or cordlike feature, may be formed during the application of the transfer tape with specialized apparatus.

A tape machine includes a base, one or more wheels connected to the base, one or more uprights extending upwards from the base, a roller connected to the base, and a tape roll housing connected to the uprights and configured to receive a roll of tape therein to allow for rotational unwinding of the roll of tape. A cutter connected to the base and moveable between an idle position and a cut position. A blade on the cutter is moveable to cut the tape when in cut position.

A tape attachment apparatus includes a tape supply unit configured to provide a tape to be attached to a tip of an electrode roll, a tape attachment unit configured to attach the tape provided by the tape supply unit to the electrode roll, and a frame configured to allow the tape attachment unit to be mounted to the frame. A tape attachment process to prevent unwinding of the electrode roll is automatically performed.
