摘要：
A support web is described for roof foundation webs which comprises a spunbonded web of polyester filaments. The spunbonded web has a basis weight of 50 to 100 g/m.sup.2 and a filament denier of 1 to 8 dtex. It has been thermomechanically preconsolidated by means of a smooth calender and end-consolidated by means of a binder. This produces a high tear propagation resistance and nail removal resistance and good dimensional stability at high temperatures. The spunbonded web is therefore particularly suitable for use as a support web for bituminized roof foundation webs.
