Abstract
Abstract A method and apparatus for making flexible reinforced hose in long lengths with the hose having a reinforcing section consisting of one or more circumferentially discontinuous or nonendless layers of reinforcing material including at least one longitudinally extending overlapped joint therein. The method includes providing at least one web of reinforcing material, applying one or more layers of flexible polymeric material to the web, folding the web to form an elongated tubular hose member with a longitudinal overlapped joint, moving the tubular member into a curing chamber of an elongated hollow curing apparatus, confining the tubular member exteriorly of the curing chamber prior to curing to prevent opening of the periphery of the member under conditions of inflation, inflating the tubular member prior to curing at least a length of the tubular member, cooling the cured length of the tubular member, deflating the cured length of the tubular member, advancing the cured length of the tubular member out of the curing apparatus, and repeating the above steps until the entire hose is cured. The apparatus includes an elongated hollow tubular curing apparatus including a curing chamber therein, means for carrying and supporting the hose components, means for moving the tubular member into the curing apparatus, means for confining an uncured length of the tubular member exteriorly of the curing chamber prior to curing, and means for inflating, cooling and deflating the tubular member and means for advancing the cured tubular member out of the curing apparatus. The method and apparatus of this invention are particularly useful for making long length water discharge hose.

Claim 1
Independent Claim
430 words
An apparatus for making flexible reinforced hose in long lengths, said hose having at least an inner layer of flexible polymeric material and a reinforcing section consisting of one or more circumferentially discontinuous layers of reinforcing material surrounding the inner layer and having at least one overlapped joint therein extending longitudinally, of the hose, said apparatus comprising in combination: A. an elongated hollow tubular curing apparatus including an elongated curing chamber for curing the hose; B. means adjacent to the entrance of said curing apparatus for carrying and supporting at least one web of reinforcing material to form the reinforcing layers of the hose, and a layer of flexible polymeric material to form the inner layer of at least a portion of the hose, said web being folded to form an elongated tubular member with at least one overlapped joint of substantial width extending longitudinally thereof, said tubular member comprising at least a portion of the hose to be made; C. flexible confining means disposed in confronting relationship to the entrance of said curing apparatus with at least a portion thereof disposed externally of said curing apparatus; D. means acting on the forward end of said tubular member for moving said tubular member including said inner layer of flexible polymeric material through said flexible confining means and then into said curing apparatus to cure a length of said tubular member, and thereby position an uncured length of said tubular member within said flexible confining means to confine an uncured length of said tubular member exteriorly of said curing chamber prior to curing to substantially enclose the outer periphery of the uncured length of said tubular member so as to prevent opening thereof under conditions of inflation; E. means for inflating said tubular member prior to curing including means for externally sealing the end of an uncured length of said tubular member which is positioned in the portion of said flexible confining means disposed externally of the curing apparatus, means for sealing the forward end of the cured length of said tubular member, and means for introducing an inflation medium directly into said tubular member through the forward end of the cured length of said tubular member to cause the outer peripheral surface of said tubular member to conform to the inner peripheral surface of said curing chamber; F. means for cooling the cured length of said tubular member after curing; G. means for deflating said tubular member; and H. means acting on the cured end of said tubular member for advancing the cured tubular member out of said curing apparatus.
