Abstract
A method is disclosed for dispensing a polyurethane mixture onto a substrate by generating a liquid mixture from reactive component resins; introducing the mixture in an inlet section of a dispensing device so as to advance it towards a planar-shaped outlet slit section, transversely to the advancement direction of the substrate; distributing the mixture along a gap chamber having a cross section diverging towards the outlet slit section; and dispensing the mixture through the outlet slit section, so as to deposit a thin, uniform film onto the substrate. Fractions of the mixture travel equal distances from the inlet section to the outlet slit section, in equal times, maintaining equal average speeds along each section having zones placed all at the same path distance either from the inlet section or from the outlet slit section.
