From old books on beekeeping found out that Dadan, which are known even to a beginner beekeeper, as side and ceiling insulation in their hives used mats of straw cutting. I use mats of Chakan, which is usually cut in early winter. The result got rid of the dampness in the hive. But in the spring after the flyby of bees re-make of the case papers. Convinced that Chakan is a great insulation.
For the manufacture of mats made a simple machine — a stand of thick boards, which are embedded in two rows of eight wooden pillars with 10-mm holes at the top.
The height of the stands and the gap between rows is determined by the width and thickness, and the distance between the outermost racks in a row — the length of the required chinnogo Mat. Between the uprights is a wooden stick, a nylon cord.
