发明名称 Protectors for printing cylinder shafts or the like
摘要 This invention relates to devices for protecting the ends of printing cylinder shafts or the like during electroplating operations, and more particularly, to devices which provide a reliable sealed enclosure operating to protect the shafts and which are readily assembled on the shafts and disassembled therefrom. The devices accommodate shafts of various lengths. They are relatively simple in construction, are readily and economically manufactured, and are easily maintained. Costs of labor and material are reduced to reduce operating costs.
