ABSTRACT:
The elongated members used in making a spiral wound hose are formed from a relatively high melting structural material but provided with a more readily fusible melting buffer material, typically as a thin layer overlying the structural material. The molten bonding material applied to the elongated members during the spiral winding process bonds well with the buffer material. The hose has enhanced structural strength and integrity.
