A Fourdrinier paper machine. A paper machine (or paper-making machine) is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by ...
The printing paper is an 8.44-by-4.5-inch (214 by 114 mm) diameter roll, and the paper tape is a 1,000-foot (300 m) roll of 1-inch (25 mm) wide tape. Nylon fabric ink ribbons are 0.5-inch (13 mm) wide by 60-yard (55 m) long, with plastic spools and eyelets to trigger automatic reversal of the ribbon feed direction.
Nicolas Louis Robert (2 December 1761 – 8 August 1828) was a French soldier and mechanical engineer, who is credited with a paper-making invention that became the blueprint of the Fourdrinier machine. In 1799, Robert patented the first machine to produce 'continuous paper'. [2][1][4] After a series of legal and financial quarrels with Saint ...
Paper drilling is a method to drill round holes into paper and other materials. For this purpose, hollow paper drill bits are clamped into a driven spindle that drills into the pile of paper. Paper drill bits are available for different hole sizes and in different coating qualities. Unlike hole punching, where only one or a few sheets may be ...

The Italian affiliate became PMT Italia under the control of the Nugo Group.
Watermarks and special paper made it harder and more expensive to forge banknotes, since more complex and expensive paper-making machines were needed. In the early 19th century (the so-called Bank Restriction Period , 1797–1821), the dramatically increased demand for bank notes slowly forced the banks to refine the technologies employed. [ 61 ]
Punched tape or perforated paper tape is a form of data storage device that consists of a long strip of paper through which small holes are punched. It was developed from and was subsequently used alongside punched cards, the difference being that the tape is continuous. Punched cards, and chains of punched cards, were used for control of looms ...
The ALU operated on only one bit of each number at a time; it kept the carry/borrow bit in a capacitor for use in the next AC cycle. [14] Although the Atanasoff–Berry computer was an important step up from earlier calculating machines, it was not able to run entirely automatically through an entire problem.
