ABSTRACT:
A method for forming on materials subjected to vertical suspension type surface treatment 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 a protuberant hook engaging part is effected by welding on the surface of the terminal part of the material under treatment while the material is in transit to a framing station. The welding can be carried out by keeping the material under treatment moved on a conveyor or keeping a welding machine moved along the conveyor. The formation of a protuberant hook engaging part can be accomplished by keeping a conductor wire supplied to the site of welding and continuously welding the wire to the lower surface of the terminal part of each of the plurality of materials under treatment thereby forming a hook engaging part made of conductor wire on each of the materials or by welding bead of the shape of a dot or line on the lower surface and/or the upper surface of the terminal part of the material under treatment to form a hook engaging part made of the ridged bead.
