Abstract
Abstract A method and an apparatus in which gas is jetted out of the gas injector 3' to support the support 2 in a contactless manner, while coating solutions are applied onto both sides of the support 2 by means of the coaters 1 and 1'. Supporting static pressure produced in a gap between the support 2 and the injector 3' is made to become 1/10 through 1/1000 of supply pressure of gas fed into the injector 3', and a lift of the support 2 at the contact point with the coating solution from the coater is made to have a value of 20 through 500μ.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
In a coating method wherein a coater and a gas injector are disposed in positions substantially opposite to each other on both sides of a support running continuously, and gas is jetted from said gas injector toward said support to coat it by said coater while supporting said support in a contactless manner, the improvement in that supply pressure of gas fed into said injector, a pressure loss in the inside of said injector and a tensile force applied to said support are set prior to coating so that supporting static pressure produced in a gap between said support and said injector becomes 1/10 through 1/1000 of the supply pressure, and a lift at the contact point with a coating solution from said coater has a value of 20 through 500μ.

Claim 3
Dependent Claim
129 words
In a coating apparatus wherein a coater and a gas injector are disposed in positions substantially opposite to each other on both sides of a support running continuously, and gas is jetted from said gas injector toward said support to coat it by said coater while supporting said support in a contactless manner, the improvement in that are included a regulator for supply pressure of gas fed into said injector and a regulator for a tensile force applied to said support which can make it possible that supporting static pressure produced in a gap between said support and said injector becomes 1/10 through 1/1000 of the supply pressure, and a lift at the contact point with a coating solution from said coater has a value of 20 through 500μ.
