  • Apparatus for cleaning stranded cable
    Patent number: 5179830
    Abstract: An apparatus for cleaning metal dust particles from a stranded cable made of metallic wires. The apparatus comprises a cleaning cylinder located downstream of a stranding die through which the stranded cable passes. Pressurized air is injected into the cleaning cylinder and impinges on the cable to entrain metal dust on the cable. A vacuum source connected to the cleaning cylinder withdraws air and entrained dust from the cleaning cylinder at a volumetric flow rate greater than the volumetric flow rate of pressurized air into the cleaning cylinder so as to generate a net inflow of air to the cylinder and prevent the egress of dust particles from the cylinder.
