    • A technique is disclosed for heat treatment of fibrous mats, especially mats formed of mineral fibers such as glass and carrying a heat hardenable binder material, such as a thermosetting resin. The method and the equipment disclosed provide for continuous feed of the mat through a curing or treating oven having a plurality of heat treatment zones or areas. In one form of the method and equipment, the heat treatment in at least one zone is effected by circulation of a heated gas, such as air, through the mat in said zone, and the mat is also subjected to heat treatment in a localized area lying within said zone by passage of a second heated gas through the mat, the second heated gas having a pressure higher than that in the surrounding portions of said zone.
    • 公开了一种用于热处理纤维垫,特别是由诸如玻璃的矿物纤维形成的垫以及携带可热硬化的粘合剂材料如热固性树脂的技术。 所公开的方法和设备提供通过具有多个热处理区域或区域的固化或处理烘箱连续进料垫。 在该方法和设备的一种形式中,在至少一个区域中的热处理是通过加热的气体(例如空气)循环通过所述区域中的垫进行的,并且垫也在局部区域中进行热处理 通过第二加热气体通过所述垫而位于所述区域内,所述第二加热气体的压力高于所述区域周围部分的压力。
