Abstract

Proceso para el revestimiento de adhesivos por fusión que comprende los pasos de: a) extruir el adhesivo de fusión en caliente a través de un orificiode un troquel adecuado; b) rociar la superficie del adhesivo extruído con un polímero de bajopeso molecular para la formación de la película derretida o unmaterial de formación polimérica, siendo el material seleccionado de forma de no reducir las cualidades de la composición del adhesivo cuando se vuelve afundir con el mismo; c) calentarla superficie del adhesivo revestido a una temperatura y durante un período de tiempo suficiente para volver a fundir elpolímero de formación de la película a fin de formar una película de revestimiento contínua y al mismo tiempo incapaces de derretir enforma considerable el adhesivo, y d) enfriar la masa del adhesivo revestido de esta manera a una temperatura adecuada para su manejo.A process for the coating of melt adhesives comprising the steps of: a) extruding the hot melt adhesive through a hole in a suitable die; b) spraying the surface of the extruded adhesive with a low molecular weight polymer for the formation of the melted film or a polymer-forming material, the material being selected so as not to reduce the qualities of the composition of the adhesive when it is re-infused with it ; c) heating the surface of the coated adhesive to a temperature and for a period of time sufficient to re-melt the film-forming polymer to form a continuous coating film and at the same time unable to significantly melt the adhesive, and d) cool the coated adhesive mass in this manner to a temperature suitable for handling.
