HOSE REINFORCEMENT LAYER AND MANUFACTURING METHOD THEREFOR, AND HOSE CAGE-TYPE FORMING DEVICE AND FORMING METHOD THEREFOR

WIPO Patent Application WO/2022/028320

A1

A hose having a hose reinforcement layer. The hose reinforcement layer (100) comprises a first reinforcement layer (1) and a second reinforcement layer (2); the first reinforcement layer (1) comprises multiple first warps (11) and first wefts (12) woven on the first warps (11) in a staggered pattern; and the second reinforcement layer (2) comprises multiple second warps (21) and second wefts (22) woven on the second warps (21) in a staggered pattern. The present invention further relates to a manufacturing method for the hose reinforcement layer, and a hose cage-type forming device and a forming method therefor. The first reinforcement layer and the second reinforcement layer are synchronously woven, so that the problem of bore matching between layers is solved, the subsequent process of inserting sleeve layers is completely removed, and the pressure bearing capacity required by design is met.
