The joints of belt filter cloths typically consist of stainless steel clippers (pin seam), protective fabric, and glue-coating. The primary connection methods for these joints are mechanical jointing and thermal jointing. Each method has distinct procedures and applications. This article provides a detailed introduction for customer reference.
Align the metal clippers at both ends of the filter cloth. The reverse-direction clip should have one more tooth than the forward-direction clip to form an interlocking offset pattern. Use matching stainless steel wire to thread through the clip holes. Once threaded, bend back and lock both ends of the wire to form a "zipper-like" closure.
Before securing the clippers, apply clipper glue to the joint area of the filter cloth to enhance the tensile strength and prevent breakage. If protective fabric is used, cover the joint area with Velcro-backed fabric, smoothing it flat to protect the joint from material abrasion.
Trim both ends of the filter cloth neatly to ensure even fiber distribution at the joint and prevent fraying.
Use specialized thermal bonding equipment to apply high temperature (adjusted according to the material type) and pressure to the joint area, allowing the fibers to melt and bond together.
Carefully control the heating time and pressure to avoid damaging the cloth or creating a weak bond. After the process, allow the joint to cool naturally to solidify the bond and prevent peeling under external stress.
After installation, adjust the tension of the equipment to avoid excessive tightness, which could cause the clips or filter cloth to break. Use an alignment device to prevent deviation of the cloth and conduct a trial run to inspect the joint’s integrity and the system’s stability.
