Rounce [1]. The rounce is a component of the printing press its [roller] is a wooden cylinder about 5 or 6 inches long and about 10 to 12 inches in diameter with a flange of two or three lines [deep] at each end; it is situated under the carriage between the two girths and has a hole through its long axis to receive its spindle. There are also two holes diagonally through the cylinder to fix the two ends of the cord called the girths [2]. See Girths. See the plates on letterpress printing.
Roller [3] in printing also means a wooden cylinder about a foot and a half long and four or five inches in diameter which must be covered with a blanket and is used in some print houses to pull proofs. It is even said that some prohibited works have been printed in their entirety using such a roller.
1. The Encyclopédie contains three articles which each describe part of the mechanism that makes up the rounce – a windlass for winding the carriage of the press in under the platen and back out again. These are Rouleau, Broche du rouleau and Corde du rouleau. The present article describes only the roller of the rounce.
2. These two parts of the cord , the girths , are wound in opposite directions around the roller so that turning the rounce one way rolls the carriage in, and the other way rolls it out.
3. rouleau This rouleau is quite different from the roller of the rounce ; it refers to a sort of hand-roller sometimes used to pull proofs from a forme.
