Abstract

The embodiment of the invention discloses a water-blocking tape connection method used for solving the problem that the water-blocking tape is broken during continuous production of unarmored dry optical cables. The water-blocking tape connection method comprises the following steps: overlapping joints of two sections of water-blocking tapes to be connected; cutting overlapping parts of the joints, wherein inclined angles are formed between the cutting direction and the extension directions of the two sections of water-blocking tapes to be connected; aligning and overlapping cut parts of the two cut sections of water-blocking tapes to be connected; connecting overlapping parts of the cut parts.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a method for splicing a water blocking tape. Background technique [0002] At present, the maximum length of the water blocking tape is 600 to 800 meters, while the length of the optical cable is generally 2000 meters or 3000 meters. Therefore, it is necessary to continue the water blocking tape in the continuous production process. [0003] With the application and promotion of FTTx (Fiber To The X, fiber optic access) network, non-armoured dry optical cables have been widely used in household pipes; Before the head mold, a longitudinal wrapping mold was installed to wrap the water blocking tape roundly on the surface of the cable core. Then directly contact the high-temperature machine head, mold and plasticized PE (polyethylene) material, and the processing temperature is about 230°C; but because the existing water-blocking tape usually uses double-sided ...
