ABSTRACT:
A shaped elemental band is provided for forming a flexible hose with wear indicating means. The base of the band is formed by a strip of flexible material which has a pair of spaced marginal edges defining the width of the strip. On top of the strip and between the marginal edges, there is provided a rib which extends along the strip and protrudes substantially thereabove. A lower bonding surface is provided at the bottom of the strip, at least a portion of which surface extends under the area between the rib and a first of the marginal edges. An upper bonding surface is provided along the top of the strip, between the rib and the second marginal edge, and is shaped to conform substantially to the lower bonding surface when the band is wound into overlapping helical convolutions with the upper and lower bonding surfaces in intimate contact. To construct the hose, the band is wound into convolutions as explained and the upper and lower bonding surfaces are joined. With this construction, the strip forms the body of the resulting flexible hose, and the rib forms a helical ridge extending along the hose. The wear of the ridge serves as a reliable indication of hose wear. In the preferred embodiments, the rib is made hollow, so that when its interior becomes visible, the user is warned that the hose is worn and should be replaced.
