PURGING SYSTEM AND METHOD FOR A PROCESS PRODUCING GLASS FIBER BLANKETS

摘要

A binder impregnated glass fiber blanket is cured and shaped by passing the blanket through a series of spaced-apart heated platen assemblies. The curing of the blanket produces vapors, fumes, odors and other pollutants which must be prevented from escaping to the surroundings of the platen assemblies. Consequently, these gases are purged from the blanket as the blanket passes between adjacent platen assemblies. Hot air is introduced from a plenum chamber onto one side of the blanket. The hot air and pollutants from the binder are drawn through and from the blanket by a suction chamber on the opposite side of the blanket. The gases from the suction chamber are then passed through an air filler and discharged to the atmosphere.
