1862 London Exhibition: Catalogue: Class 7.: Bryan Donkin and Co
1585. DONKIN, B., and Co, Near Grange Road, Bermondsey.
Paper-making machine and paper- cutting machine.
Obtained the Council Medal in Class 6, in London, in 1851.
PAPER-MAKING MACHINE on the same principle as those erected by Mr. Donkin, of Bermondsey, at Frogmore, in Berks, in 1803, and at Twowaters, in Hertfordshire, in 1804, which were the first machines ever used for making endless paper. The machine's for clearing the pulp, and for drying and cutting the paper, were subsequent inventions, and admit of great variation in their construction.
DRYING MACHINE.
1. Cast-iron sand catcher, coated with zinc.
2. Knot strainer, with brass plates, a parallel motion being given to this knotter, a uniform action over the whole plate is secured.
3. Machine with endless wire, 7 ft. 6 in. wide, 34 ft. long, with improved deckles, self-acting guide for the wire, and rider roll of perforated copper (Wilkes's patent).
4. Drying machine, consisting of 6 steam cylinders, 4 ft. diameter.
5. Two sets of smoothing presses.
6. Cutting machine of improved construction, for cutting the endless paper into sheets as it leaves the smoothing presses, without the intervention of reels.
Although the machines Nos. 3, 4, and 6, are drawn separately, they form one continuous machine; the pulp being supplied at one end, and the dry paper being delivered at the other, in sheets of the size required.
A machine of this description would make an endless sheet of paper about 20 miles long in 24 hours, which would cover about 17 acres, if kept continuously at work.
