Description

technical field

[0001] The invention belongs to the technical field of rubber fenders, and in particular relates to an arc-shaped rubber fender, its preparation method and manufacturing equipment. Background technique

[0002] Conventional fenders are long strip type, drum type, and cylindrical type. They generally have a flat installation surface, installed on the prefabricated plane of the wharf, and achieve good contact with the wharf surface, but many wharf corners , The corners of the piers are all arc-shaped, and conventional fenders cannot be installed.

[0003] For example, the Chinese invention patent application with application number 201510541392.7 discloses a marine fender, including a buffer body, fixed sides are symmetrically arranged on both sides of the buffer body, and the buffer body is arranged as a rectangular tubular structure with an arc at one end , fixed holes are arranged on the fixed side; although the buffer body is designed to be arc-shaped in t...
