Beschreibung
Zusammenfassung:	La presente invención se refiere a una banda sustentadora para bandas subyacentes de techos, la cual consta de una membrana tejida de filamentos de poliéster y especialmente de tereftalato de polietileno, caracterizada porque la membrana tejida, tiene un peso superficial de 50 a 100 g/m cuadrados, con un título individual de los filamentos, de 1 a 8 Dtex y se solifica preliminarmente, por la vía termomecánica con aplicación de una calandria lisa y luego se solifica definitivamente por una armadura de aglutinante. There is described a supporting web for sheets spread under a roof which comprises a spunbonded web made of polyester filaments. The spunbonded web has a basis weight of 50 to 100 g/m and a filament denier of 1 to 8 dtex. It has been thermomechanically preconsolidated by means of a smoothing calender and end-consolidated with a binder. This produces a high tear propagation resistance and a high nail pull- out resistance and also good dimensional stability at high temperatures. The spunbonded web is therefore particularly suitable for use as a supporting web for bitumenized sheets spread under a roof.
