Abstract

In order to easily ensure sealing properties, a gas sealing structure (30) is provided with: a sealing roller (40) which divides a drying chamber (11) and is disposed on the surface side opposite to the surface on the drying chamber (11) side of a partition wall (15) having an opening (16) through which a sheet-like member (S) passes; a conveyance section labyrinth seal (60) that is disposed at a position facing the outer peripheral surface (41) of the seal roller (40), that allows the sheet member (S) conveyed from the opening (16) to pass through to a position between the conveyance section labyrinth seal (60) and the seal roller (40), and that has a plurality of space sections (67) that are arranged in the conveyance direction of the sheet member (S) and that are open on the seal roller (40) side; and an exhaust duct (22) that causes the inside of the drying chamber (11) to have negative pressure with respect to the side where the seal roller (40) is disposed.

Description

technical field [0001] The present invention relates to a gas sealing structure and an extraction and drying apparatus. Background technique [0002] A manufacturing apparatus for forming a sheet-like member of a resin film generally has a plurality of processing steps, and the sheet-like member is formed through each processing step. However, in the processing step at the time of forming, the sheet-like member is conveyed from a processing chamber In some cases, it may be necessary to convey the sheet-like member while suppressing outflow of gas from the processing chamber. As one method for conveying the sheet-like member while securing the airtightness and suppressing the outflow of gas, it is conceivable to arrange a tank filled with water at the outlet of the processing chamber, and to immerse the outlet of the processing chamber in water to suppress the gas The method of outflow from the processing chamber. However, in this case, the sheet-like member transported fro...
