Abstract
A process for impregnating a continuous sheet of glass fibre web, paper, carbon fibre, cloth etc., which comprises feeding the sheet continuously into a closed vessel filled to a suitable height with a polymer solution, immersing the sheet under the surface of polymer solution while causing solvent boiling to occur and solvent vapor bubbles to flow out of the sheet, whereby bubbles of gas, such as air held or absorbed in the sheet during the immersion, are automatically removed from the sheet and then withdrawing the sheet from the vessel.
