The dryer hose attachment apparatus provides a coupling with more than one embodiment. Each coupling rotationally engages the outlet hose provided for the dryer and the initial hose of a flex hose provided for exhausting air from a dryer environment. Each coupling provides for sealing the dryer exhaust air, from the dryer to the flexible exhaust hose. Each coupling provides for the apparatus to be fitted and to operate in close confines typical to clothes dryer environments. The flange of the dryer attachment may be fixed to the dryer via fasteners. The interior of the outlet hose of the dryer attachment provides sizing for interference fit around an existing hose which exits a dryer. And, both means of engagement may be employed.

A tapering apparatus is mounted on a table platform for tapering a sheet of foam insulation. The apparatus utilizes a rotating wire through which a current is applied in order to heat the wire. The temperature of the wire is maintained above the melting temperature of the foam insulation so that the insulation is melt and cut as it is forced across the wire. A conductive wire forms an endless belt positioned around a pair of rotatable sheaves. The wire is responsive to the angular rotation of the drive sheave. The sheaves are vertically adjustable in order to set a desired height and cutting angle for the tapering of the sheet of insulation. The current flowing through the wire is controlled such that the wire is heated to a temperature above the melting point of the foam insulation. A variable speed motor is connected to the drive sheave which is used to rotate the wire about the sheaves. The sheet of foam insulation is then forced into the rotating wire. The heat and rotation of the wire evenly melts the insulation and tapers the foam insulation sheet as it is forced across the wire.
