The Coming of the Winder |
|
Notes on development of the early printing presses. Prior to the year 1851 paper delivered in rolls was rarely seen. But in that year Theodore Nelson of England developed a printing press that utilized endless rolls of paper instead of sheets that were picked up from reams that had to be manually fed into the press. The rotating cylinder press had been patented six years earlier by American Richard Hoe. It is fair to say that Mr. Nelson's invention was merely an add-on to Mr. Hoe's machine. Further improvement of Mr. Nelson's press was done in the US by William A. Bullock, and his version more or less became the blue-print for all presses built during that period. The first machine of this type was put to work in the press room of The Philadelphia Enquirer in 1865. The trouble with rolls.... With improvement of the presses, speed picked up and demand for better quality rolls came along. One of the problems was that large rolls were too softly wound. Eventually, it became obvious that existing winding technology was inferior. The trouble with winding.... In the 1860's winders as we know them today were not yet invented. Rolls were wound on shafts in slitting and winding stations directly on the paper machine. Such arrangements were positioned where we find the reel on today's paper machines. Power for each winding shaft was supplied by the paper machine main drive. Care had to be taken to see that tension was even in all webs and if a break occurred, splices could not be made in the usual manner. Instead rolls had to be rewound and spliced on some simple shaft to shaft rewinding device. Rolls wound in the described manner were of course center wound. The coming of the winder. Towards the end of the 1860's Carl Theodor Bischof, Director of Papierfabrik Schlögmühl near Gloggnitz, Austria, had ideas of a winding device separate from the paper machine. In 1873 the first winder of Mr. Bischof's design went to work in the Schlögmühl paper mill. The machine was built by J. M. Voith of Heidenheim, Germany.
The Bischof-winder.
Obviously, the original Bischof-winder wasn't the
prefect answer to the problems encountered. While today's winders have
two drums, the Bischof-winder had only one, on which the set of rolls
being wound balanced. Because of this, the set was easily brought into
vibrations. This in turn caused the slitters, which cut directly on the
set, to "work" in the set, causing the formation of large
amounts of dust. When the rolls reached the printing rooms, the presses
got "dusted", which obviously was to the disliking of the
printers.

From trucking to winding. Whether we like it or not paper rolls in various sizes and diameters have come to play an important role in most people's lives. Up until the fall day in 1977 when I climbed out of my truck and got my first job in the paper industry, I hadn't given much thought to the fact that rolls had to be made in some way. Maybe I had some vague idea that some sort of machinery was involved in the process, but the rest was beyond my troubled mind. On my first day at the new job I discovered that there was a machine called the winder, and that was where the rolls were made. I was put to work as assistant to Mr.Sigurd Moen - the winder operator. Somewhat later, I also got to know Mr.Werner Meyer - at that time erecting engineer at Maschinenfabrik Goebel in Germany.
Neither of us here at The Paper History Channel have
ever seen any of the above described winding devices nor have we seen a
Bischof-winder. If any of you
visitors have seen one, we welcome your comments.

Paper rolls of every conceivable size have become part of our everyday life. rolls of newsprint. Rolls for the household. |
