A method and apparatus are provided for peeling a thin film (90), typically 100 microns or less in thickness, from a liner (80) by use of a rotatable peel rod (50) supported in an air bearing. The air bearing comprises a support plate (40) having arcuate surfaces (41,42) which are substantially coaxial with a cylindrical film-bearing segment of the peel rod (50). Air openings in the arcuate surfaces conduct a flow of air into an air bearing gap (51,52) between (41,42) the arcuate surfaces and the peel rod (50).
L'invention concerne un procédé et un appareil permettant de décoller un film mince (90), généralement de 100 microns maximum d'épaisseur, d'un revêtement (80) au moyen d'une tige de décollement rotative (50) maintenue dans un palier à air. Ce palier à air comprend une plaque de support (40) dotée de surfaces arquées (41, 42) qui sont sensiblement coaxiales avec un segment de palier à air cylindrique de la tige de décollement (50). Des ouvertures d'air (51, 52) pratiquées dans les surfaces arquées conduisent un flux d'air dans un espace de palier à air (51, 52) logé entre les surfaces arquées (41, 42) et la tige de décollement (50).
