MARKING ROLL FOR TIN ELECTROPLATED STEEL SHEET

摘要

PROBLEM TO BE SOLVED: To provide a marking roll which facilitates exchanging of rubber rings and can make a working load less in changing the mounting of the marking roll with the rubber rings at every changing of coating weights according to orders and changing over of materials in order to manufacture a tin electroplated steel sheet. SOLUTION: The marking roll for the tin electroplated steel sheet is constituted by freely attachably and detachably providing a roll body with the mark rings mounted with the rubber rings on the outer periphery of circumferential rings. The marking roll for the tin electroplated steel sheet is constituted by freely attachably and detachably providing the roll body with the mark rings described above and spacers. The reduction of the working load is made possible by rapid exchanging of the mark rings and the mark troubles of the electroplated steel sheet can be decreased.
