Case-making machines may be modified for use of paper as the covering material, to make round-cornered eases, to use light board instead of paper for the inlays, and to make album covers which have one narrow and one wide board, with a hinge. Modern ease-making machines can produce up to 21 cases per minute with dimensions of 5 1/2 by 7 1/2 inches to 9 1/2 by 15 1/2 inches, with extended capabilities using accessory equipment.
The case-making machine dates back to the latter years of the 19th century; its greatest period of development was 1891-95. (89 , 196 , 203 , 320 )
