ABSTRACT:
A method for working terminal parts of materials subjected to vertical suspension type surface treatment thereby forming in the terminal parts such hook engaging parts as to be engaged with nipping devices of a carrier bar serving to convey the materials successively to a series of surface-treating baths is disclosed. This method is characterized in that the formation of the hook engaging part in the terminal part of the material is carried out at the same time that or after the step of cutting an extruded material into a fixed length is performed. The hook engaging part may be a groove, notch or hole formed in the terminal part of the fixed-length material and may be formed by a cutting or pressing work. In another embodiment, a protuberant hook engaging part is formed by welding on the surface of the terminal part of the fixed-length material while the material is in transit to a inspection table.
