Cover Art of Paper Makers at Work from Scientific American The Weekly Journal of Practical Information Vol. CIX No. 14 October 4, 1913 by Howard V. Brown |
Now there are things in this image tells you about paper making. The workers have the shirt sleeves cut off and their pants cut off or rolled up. This tells you the work is hot. The well muscled body of the winder operator says the work is heavy. The conferring superindent and backtender signifies that paper making requires knowledge and experience. The bare feet show that the process is wet and would ruin shoes if they were worn. There is a brass oiler and galvanized transport can and funnel in the picture. To me these represent the need for lubrication of mechanical equipment and the need chemical additives to facilitate the processing. The reason I say they later is that I am guessing the galvanized transport container has light mineral oil or kerosene in it. These oils would be applied to the calendar stack rolls during a break to clean the calendar roll surfaces and to prevent the calendar rolls from picking sticky places from the paper surface once the sheet was threaded through the calendar stack again.
