  • Patent number: 5965198
    Abstract: Disclosed is a process for the manufacture, by coating, of a plastic web. A plastisol is deposited as a layer onto a flat support, to obtain a coating layer in the pasty state. Before the plastisol is gelled, powdering is performed by accelerating particles of plastic powder toward, the external surface of the coating layer. The powder includes particles of a thermoplastic material capable of at least partially being integrated into or dissolving in the plastisol. The particles are homogeneously incorporated in order to form a single matrix with the thermoplastic base material of the plastisol.
