Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a roll for conveyance and cooling of a long film which includes a gas introduction mechanism having a structure which can be produced easily at low cost.SOLUTION: In a roll 56 which winds and cools a long film F conveyed in a roll-to-roll manner in a vacuum chamber 51, a plurality of gas introduction grooves 3 extending in a central axis 11 direction in a region in which the long film F is wound out of an outer peripheral surface of the roll 56 are provided across the whole periphery with a substantially equal interval in the circumferential direction of the roll 56. With each of the plurality of gas introduction grooves 3, a gas supply groove 4 provided in parallel with respect to the central axis so as to reach the outside of the region from at least one end part of the gas introduction groove 3 is communicated. The gas supply groove 4 is lidded with a resin or metal sheet 5, and a gas supply port 6 is provided on an end part on the opposite side from the end part communicating with the gas introduction groove 3.SELECTED DRAWING: Figure 2
【課題】 低コストで簡易に作製できる構造のガス導入機構を備えた長尺フィルムの搬送および冷却用ロールを提供する。【解決手段】 真空チャンバー51内においてロールツーロールで搬送される長尺フィルムFを巻き付けて冷却するロール56であって、ロール56の外周面のうち長尺フィルムFが巻き付けられる領域に中心軸11方向に延在する複数のガス導入溝3がロール56の円周方向に略均等な間隔をあけて全周に亘って設けられており、これら複数のガス導入溝3の各々には、ガス導入溝3の少なくとも一方の端部から該領域の外側にまで至るように該中心軸に対して平行に設けられたガス供給溝4が連通しており、ガス供給溝4は樹脂製または金属製のシート5によって蓋がされており且つガス導入溝3に連通する端部とは反対側の端部にガス供給口6が設けられている。【選択図】 図2 |
