for the supply of inflating medium from the aircraft supply gum plies 32 33 and reinforcing fabric material 34 encompass the supporting member 30 which supporting member 30 is cemented to the bottom ply 15 the above described plies of resilient rubberized materials are impervious to the inflating medium manifold ply 25 may have a central passageway therethrough that communicates with the respective ports or channels in the tubular members 16 in the manufacture of the deicer boot 10 described above the various plies parts and tubes are assembled and cemented together with tube 16 being compounded to include cross linked natural rubber greater than 1 by weight which cross linked rubber prevents flow during cure ordinarily the deicer is cured by steam having the steam enter the respective tubes during the actual cure to maintain the tubes 16 in a distended condition to prevent adhesion of the inner surfaces in curing the deicer pad by this method the steam can penetrate voids or pockets of material that were not properly sealed or cemented and adversely affect the quality of the end product in the instant invention the deicer pad in its assembled condition without the air connecting means 30 is covered by a bleeder material such as heavy duty paper the paper and deicer are then covered with a suitable cover ply that overlaps both to assure a positive seal around the edges the cover ply has a small bore in it such that.
