The present invention relates to a method for manufacturing an aerogel sheet and comprises: a step (a) of impregnating an acid solution into a fiber sheet to clean the fiber sheet by using the acid solution and impregnating a binder solution into the fiber sheet that is cleaned by using the acid solution to manufacture a pre-processed fiber sheet; a step (b) of impregnating a silica precursor into the pre-processed fiber sheet; and a step (c) of a gelling catalyst into the fiber sheet into which the silica precursor is impregnated to gelate the silica precursor.

An electronic dispenser comprising a housing; a feed roller rotatably mounted within the housing; a motor operable to drive rotation of the feed roller, and wherein the motor is at least partially within the feed roller; and wherein actuation of the motor results in a noise level, external to the housing, of less than 53 A-weighted decibels.

The present invention relates to a method for unwinding a bobbin of a coiled sheet, the method comprising: providing a bobbin of a coiled sheet, the bobbin comprising a free portion of the sheet unwound from the bobbin; arranging a blade between the free portion of the sheet and the remaining of the sheet coiled in the bobbin in such a way that the blade is in contact to the sheet coiled in the bobbin; and vibrating the blade while unwinding the sheet from the bobbin. The present invention also relates to an unwinding apparatus for unwinding a bobbin.

To easily specify the position of a defect in a separator, a method for producing a separator original sheet (12b) includes the steps of: forming a separator original sheet (12b) including a separator original sheet (12c) and a heat-resistant layer coated on the separator original sheet (12c); detecting a defect (D) in the separator original sheet (12b); and recording information including information on a position of the defect (D) which position is a position in the width direction of the separator original sheet (12b).

Disclosed is a sealing device for securing a packaging material. The sealing device for securing the packaging material comprises: a tape supply reel for supplying a sealing tape to which an RFID tag has been coupled; and a sealing part for sealing, with the sealing tape, an opening of a plastic packaging material holding a product, wherein the sealing part adheres the RFID tag, which is coupled to one end of the sealing tape having the length for one use, to an adhesive positioned on the other end portion of the sealing tape having the length for one use, wherein the RFID tag is broken by the adhesive strength with respect to the other end portion when the sealing tape sealing the plastic packaging material is torn.
