A tarp deployment system for unwinding and taking up a flexible tarpaulin. The system includes a tarp deployment machine and a spool configured to receive and retain a flexible tarpaulin. A spool gear extends radially from at least one end of the spool. A cylindrical cage has a series of parallel shafts parallel to an axis shaft of the cage. A cage gear extends from the cage axis shaft and a drive mechanism drives the cage gear in order to rotate the spool. Power is transmitted to the cage gear which then rotates the cylindrical cage which engages and rotates the spool gear.

Discussed is an apparatus for notching an electrode sheet, the apparatus including a transfer unit having first and second transfer rollers provided on a bottom surface of the electrode sheet to transfer the electrode sheet at regular intervals, a jig unit provided below the electrode sheet, and supporting the bottom surface of the non-coating portion and a notching unit provided above the electrode sheet to notch the non-coating portion supported on the jig unit to provide the electrode tab, wherein the jig unit includes a rotation member provided between the first and second transfer rollers and rotated in a direction perpendicular to a transfer direction of the electrode sheet, two or more jigs provided on an outer circumferential surface of the rotation member to alternately support the non-coating portion disposed between the first and second transfer rollers when the rotation member is rotated.

Described herein is an array of finished products, each finished product in said array may have a Percent Compressibility of greater than 3.00% and an actual length ranging from about 10.955 inches to about 11.045 inches. The finished products may be paper towels, where the actual length is different for at least two finished products of the array and where at least one of the finished products of the array of finished products may comprise a protruding core and where at least one of the finished products may comprise a hidden core, and where each of the finished products are in a package.

A mask dispensing assembly includes a housing that is positionable in a public transportation vehicle and the housing has a dispensing slot extending into an interior of the housing to dispense face masks stored in the housing to the passengers. A lifting unit is positioned within the housing to lift a stack of disposable face masks in the housing thereby aligning a topmost one of the stack of disposable face masks with the slot. A dispenser is positioned in the housing to urge the topmost one of the stack of disposable face masks outwardly through the slot. A switch is positioned in the public transportation and the lifting unit is actuated when the switch is depressed to facilitate the driver to dispense a disposable mask for a passenger to wear.

Discussed is an apparatus for notching an electrode sheet for an electrode tab, the apparatus including: a transfer unit including first and second transfer rollers to continuously, transfer the electrode sheet at regular intervals; a jig unit disposed between the first and second transfer rollers, and supporting a non-coating portion of the electrode sheet; and a notching unit to notch the non-coating portion supported on the jig unit, wherein the jig unit includes: a rotation member provided between the first and second transfer rollers and rotated in a direction perpendicular to a transfer direction of the electrode sheet; and two or more jigs to support the non-coating portion disposed between the first and second transfer rollers, and the jig unit is able to improve a supporting force of the electrode sheet, to prevent the electrode sheet from vibrating, and accurately notch an electrode tab to the electrode sheet.

An apparatus for manufacturing the electrode assembly, in which an electrode and a separator are alternately stacked on a stack table, and the separator is folded in a zigzag shape so that the electrode is disposed between the folded separators to manufacture the electrode assembly, has a separator supplier configured to supply the separator to the stack table, and a separator tension adjuster configured to constantly adjust tension of the separator supplied to the stack table. The separator supplier comprises a separator winding roll around which the separator is wound, and the separator tension adjuster adjusts a. supply height of the separator winding roll to adjust the tension of the separator.

A winding machine for web-type materials, in particular film materials, comprises a feeding device and at least one winding shaft which is capable of being driven and designed to receive a winding core for the winding of the web-type film material, wherein the winding machine is allocated a system for regulating and/or reducing an electrostatic charge of the web-type material during the winding process.

Described herein is an array of finished products, each finished product in said array may have a Percent Compressibility of greater than 3.00% and an actual length ranging from about 10.955 inches to about 11.045 inches. The finished products may be paper towels, where the actual length is different for at least two finished products of the array and where at least one of the finished products of the array of finished products may comprise a protruding core and where at least one of the finished products may comprise a hidden core, and where each of the finished products are in a package.

A web splicing apparatus is disclosed that includes a web unwinding unit configured to hold a running web material roll and a new web material roll and to unwind webbing from the running web material roll and a web splicing unit operable with the web unwinding unit to selectively splice the webbing of the running web material roll with webbing of the new web material roll. The web splicing unit further includes a cutting assembly configured to selectively sever the webbing of the running web material roll, a web deflection device, an actuator system configured to linearly translate the web deflection device in a first direction and a second direction opposite the first direction, and a locking mechanism operable in a locked state and an unlocked state to selectively prohibit and enable movement of the web deflection device in the first direction and the second direction.

Described herein is an array of finished products, each finished product in the array having a length relative error of less than 0.81% of a target length, H is disclosed. The finished products, which may be toilet paper and kitchen towels, are formed from transversally cutting elongate logs of convolutely wound web materials.
