Industrial methods have now largely replaced hand-beating and dipping and drying, with mechanical agitators to beat pulp, and high-pressure jets and conveyor belts to spray it and spread it, and vacuums and cylinders and presses to dry it, and rollers to polish it, but there are still really only three stages in the whole paper-production process: the preparing of the pulp; the forming of the paper on a mould or a mesh; and the drying and finishing. In a modern paper plant, these stages translate into a process that goes something like this. Bales of wood pulp are fed into a hydrapulper, in which the pulp is diluted with water and mixed – think of a hydrapulper as a giant Moulinex, and the pulp as paper-gruel. The porridge-like substance produced – the ‘stock’ or ‘stuff’ – can then be further diluted and undergo further beating, or fibrillation, to cut and break up the fibres of the pulp, and screened to remove impurities, and blended with various additives. Then, and only then, is the stuff ready for the papermaking machine proper. A typical modern machine is mind-bogglingly huge: hundreds of metres long, costing millions, running twenty-four hours a day and capable of producing hundreds of thousands of tonnes of paper every year. The slurry, or stock – which looks like milk at this stage, or at least a kind of thin white water – passes through a ‘flow box’ or ‘head box’, where it is sprayed onto a mesh conveyor belt. As the stock is sprayed, the water drains through the mesh, leaving behind a fibrous mat, just as in the early Japanese hand moulds, only on a massive scale, and at astonishing speed. The stuff then passes through heavy rollers, with more moisture being squeezed and sucked out, and beneath a dandy roll, and through steam-heated drying cylinders and a size press, where sizing is added – the starch that reduces absorbency – and then over the calender, the big iron rollers which polish and glaze the surface of the paper, and finally it passes onto large reels, ready to be cut into sheets or split into smaller reels and packed for despatch to paper merchants and converters who will produce and package the paper ready for you to print out your essential emails and flight boarding details.
Papermaking: the same yesterday, today and tomorrow

It is an amazing sight to see a modern paper machine in full flow, even now in the twenty-first century: in the nineteenth century it was nothing less than astonishing. Herman Melville, that great nineteenth-century chronicler of astonishment, describes a paper mill in his story ‘The Paradise of Bachelors and the Tartarus of Maids’ (1855), in which the narrator visits a mill which is oddly but reassuringly very like a whale, a ‘large whitewashed factory’, ‘like an arrested avalanche’. This vast white beast, which swallows up rags and water and people, is located ‘not far from Woedolor Mountain in New England … By the country people … called the Devil’s Dungeon’. The narrator of the story is a businessman, ‘Having embarked on a large scale in the seedsman’s business’, who is seeking a cheap wholesale source for seed packets. Inside the factory he stands, amazed:
Something of awe now stole over me, as I gazed upon this inflexible iron animal. Always, more or less, machinery of this ponderous, elaborate sort strikes, in some moods, strange dread into the human heart, as some living, panting Behemoth might. But what made the thing I saw so specially terrible to me was the metallic necessity, the unbudging fatality which governed it. Though, here and there, I could not follow the thin, gauzy veil of pulp in the course of its more mysterious or entirely invisible advance, yet it was indubitable that, at those points where it eluded me, it still marched on in unvarying docility to the autocratic cunning of the machine. A fascination fastened on me. I stood spellbound and wandering in my soul. Before my eyes – there, passing in slow procession along the wheeling cylinders, I seemed to see, glued to the pallid incipience of the pulp, the yet more pallid faces of all the pallid girls I had eyed that heavy day. Slowly, mournfully, beseechingly, yet unresistingly, they gleamed along, their agony dimly outlined on the imperfect paper, like the print of the tormented face on the handkerchief of Saint Veronica.
Who could possibly have conceived of such a monster, such a panting Behemoth? A man called Louis-Nicolas Robert could. Like Melville, Robert too saw the pallid faces of the workers in the pallid incipience of the pulp, though where Melville saw agony and torment, Robert saw freedom and liberation. In its very incarnation, by its very originators, the papermaking machine was seen as a metallic necessity, a triumph of technology over man.
Louis-Nicolas Robert, born in Paris in 1761 and nicknamed ‘the Philosopher’ at school, became a soldier in the French army, in the First Battalion of the Grenoble Artillery. Restless and dissatisfied, and with no prospect of promotion, he eventually found himself back in Paris in the very midst of the French Revolution, working as ‘an inspector of personnel’, a classic petit cadre, in a paper mill at Essonnes, to the south of Paris, where he was appalled by the behaviour of the workers, who had become infected with the ideas of the times. Encouraged by his employer, François Didot, Robert began experimenting with plans for a machine that could replace the troublesome papermakers. After much trial and error just such a machine was devised, and on 18 January 1799 Robert was granted a patent for a papermaking machine to make ‘sheets of an extraordinary length without the help of any worker’. Ironically, Robert and Didot then began wrangling between themselves, arguing about money and the patent, but since neither man could afford to make a success of the enterprise alone, Didot called upon his brother-in-law John Gamble, an Englishman, who took drawings and samples of the machine-made paper to London in 1801, hoping to find investors. Gamble got lucky: he managed to persuade a famous, wealthy family of London stationers, the Fourdriniers, to back him, and together they were soon granted an English patent for an ‘Invention for Making Paper’ (‘in single sheets, without seam or joining, from one to twelve feet and upwards wide and from one to forty feet and upwards in length’). The industrial history of papermaking had begun.
Robert’s machine was brought from France in 1802, and the Fourdriniers employed a young man called Bryan Donkin to modify and improve it. Like Robert a genius in the pay of the boss class, Donkin became a kind of consultant inventor who worked out of a factory set up for him by the Fourdriniers in Bermondsey, where he established the first British cannery, was responsible for developing split steel nibs for pens, designed and improved metalworking tools such as lathes and drills, and ended up advising Marc Isambard Brunel in his work on the Thames Tunnel. But the paper machine was his first big break. He set about making a series of improvements to Robert’s prototype, removing the vat from below the wire and eventually replacing the hand-operated crankshaft with a mechanical drive. The first improved Fourdrinier machine was set up at Frogmore Mill in Hertfordshire in 1803, and remains the effective template for all modern paper machines: a moving belt made of wire mesh has stock poured onto it, water drains through the mesh, leaving a fibrous sheet, which is cut into sections and hung out to dry, as indeed were the Fourdriniers, who had poured money into the enterprise and found themselves bankrupt by 1810, having made a net loss on the machine of over £50,000, though years later Parliament granted them some small compensation for ‘being reduced to comparative poverty in the evening of a long life spent in the execution of a great national object’.
The great national object did not meet, however, with universal acclaim. As it was for the mighty Fourdriniers, so it was for the lowly workers, only more so: the machines stole not their capital but their livelihoods. More and better machines meant that fewer and less-skilled people needed to be employed. The machine became an enemy. During the Swing riots that spread throughout England in 1830 a number of paper mills were attacked – in Norfolk, Wiltshire, Worcestershire and Buckinghamshire. Most of those involved seem to have been members of the Original Society of Papermakers, who were furious and fearful for their futures. But, alas, the riots solved nothing. Several paper manufacturers went out of business, and those workers who were tried and found guilty were transported to Tasmania. The march of the machines continued.
Progress was relentless. The cylinder machine СКАЧАТЬ
