HOSE WITH COMPOSITE JOINTS

摘要

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. A flexible plastic hose apparatus is constructed by spirally winding elongated members. The elongated members are formed from a relatively high melting structural material, but provided with a more readily fusible melting buffer material. This buffer material is typically a thin layer overlying the structural material. Molten bonding material is applied to the elongated members during the spiral winding process and such material bonds well with the buffer material. The hose so constructed has enhanced structural strength and integrity.
