BOOTSTRAP-TYPE HOSE USING BIAS-CUT FABRICS

摘要

BOOTSTRAP-TYPE HOSE USING BIAS-CUT FABRICS There is disclosed a method of producing a hose having improved axial strength comprising the steps of: (a) providing a strip of fabric having two sets of cross-weft cords which intersect each other at an intersect angle of about 40.degree. to about 160.degree.; (b) providing a cylindrical tube having a longitudinal axis; (c) applying a first layer of said fabric around said tube such that one set of cross-weft cords lays parallel to said longitudinal axis and the other set of cross-weft cords lays at an angle from said longitudinal axis equal to said intersect angle; and (d) applying a second layer of said fabric around said first layer such that one set of cross-weft cords of said second layer lays parallel to the longitudinal axis and the other set of cross-weft cords of said second layer lays at an angle from said axis equal in magnitude but opposite in direction to the angle of the other set of cords of said first layer.
