Gilding around 1960
Around 1960 the books were placed into special wooden presses for the gilding precedure.
There were pressed together as many books as possible.
Before gilding the edges had to be sanded
To simplify the sanding procedure a hand sanding machine was used.
The corners must have prepared separately with a special hand sander.
After sanding the gold was applicated by hand.
The gold must have been pressed by hand to avoid that it peels off the book.
The foil has been polished to get a glossy look.
Before the delivery of the goods a final inspection was done.
