Abstract
The present invention relates to an improved lifter for a blast cleaning apparatus for cleaning coiled wire with abrasive cleaning material. A prior art apparatus for blast cleaning wires comprises an elongated boom provided with annular splitters for longitudinal separation of wire coils and metal lifters for radial separation of wire coils to expose substantially all of the surface of the wires to the abrasive cleaning material. Due to the hardness of the lifters, some abrasive cleaning material becomes embedded in the wire and causes problems with subsequent processing steps. The present invention provides a resilient lifter for a blast cleaning apparatus which overcome this and other difficulties. Preferably, the lifters according to the present invention are made of polyurethane and are used in combination with a conventional boom with or without splitters.
