<p>A method of and an apparatus for drying/curing a dry material such as a mat of fibrous or powder material as may be used for building purpose as well as a non-dry material such as a thermosetting resin are disclosed. The disclosure relates to the sealing function during the drying/curing step. The apparatus comprises a heating and blowing mechanism for drying/curing a mat as it is being conveyed by a conveyor mechanism including pair of upper and lower conveyors, and shield mechanism for shielding between the conveyor mechanism and the heating and blowing mechanism. The shield mechanism includes wire brushes on blowing boxes of the heating and blowing mechanism for abutment against caterpillar plates of forward runs of respective conveyors to seal between the caterpillar plates of the forward runs and the blowing boxes. Any powder or particles which may be developed during the drying/curing step is trapped by the wire brush, which is then effective to prevent a leakage of a hot air, thus assuring an even pressure of hot air supplied. The wire brushes are disposed in a plurality of rows and divided into stationary and movable ones. By moving the movable wire brushes for movement toward or away from abutment against the caterpillar plates of the forward runs, selected flexible caulking members are operated to provide a variable shielded width.</p> |
