Hollander Beater

The Hollander Beater
During the early 1600s the stamper was still in use for the maceration of fibers.   But in Holland they were faced with the problem of how to power the stamper.   The most common power source was wind power, generated by windmills.   Wind though was unreliable, unlike water it did not flow in a single path and the mill may not always be in that path.   Stamping was an action done with brute physical impact against the fiber.   Later on during the late 1600s, due to the higher demand for paper and the unreliable wind power of the mills, the Hollander Beater had been developed.
Created in Holland, hence the name Hollander Beater was a play off the Edgerunner which had been used to grind things like mustard seed and tobacco.   The Dutch had realized that with the Edgerunner they already had a strong, quick, and more efficient grinder.   The Edgerunner though had been a great industrial tool made from large round stones that where made to roll in circles to grind materials. The Hollander Beater is of a smaller size in comparison and instead of the use of stone, a metal cylinder with teeth attached to with was put into place.   Replacing the stampers that had been in use for the maceration of the fibrous materials, the Hollander Beater was more efficient.   It allowed for paper makers to skip the step of fermentation, with the rolling blade like teeth the fibers were more thoroughly macerated.   Also, without having to ferment the fibrous material, the process of papermaking had been sped up incredibly, allowing for papermakers to meet increasing demand for quality paper.  
The Hollander Beater is made as a circular track where the blades macerate the pulp while pushing it around the track, which is filled with water to maintain hydration, so that the pulp is continuously beaten without pause.   During the 1800s the beater was developed an all purpose feel.   It was being used as a replacement for fermentation; it had also been installed with a screen...
