1. A finishing tool consisting of a brass wheel, the circumference of which is engraved so as to impress a continuous repeating pattern as it revolves under (considerable) pressure. The decorative roll was used in Germany at least as early as the 1460s, and was in common use by the second decade of the 16th century. Most of these early rolls were cut intaglio, so that the design on the leather was raised, but many were also cut in relief. The average length of the pattern impressed by early rolls was approximately 5 to 6 inches, which would give a wheel diameter of approximately 1.6 to 1.9 inches. The common diameter of rolls used today is about 3.5 inches, which is capable of producing an impression of about 11 inches in length. The smaller size, however, is still in use. Rolls have been produced in an enormous variety of designs, including simple lines, simple and intricate patterns, as well as edge and title rolls. 2. The design impressed by a roll.
