5. The yarn bundling machine and the water blocking tape pay-off rack are independently placed, two independent yarn bundling machines are needed for yarn bundling in a yarn bundling mode, occupied area is large, and the space utilization rate of a workshop is low.
6. The cabling process and the sheath process are separated, the cable core is required to be transported to the sheath process after being taken off the machine for production, the production period of the product is longer, and the labor cost is higher.
