Wimmerwuchs
Wimmerwuchs or wimmer describes various growth anomalies in wood .
features
Wimmerwuchs is a banding, visible on the trunk jacket, with wavy fibers and tree rings, lying transversely to the trunk axis in a tangential direction. The wood fibers "swing" with the tree rings.
root cause
A clear, causal cause cannot be described today, but certain connections are suspected with the site conditions. Wimmer growth occurs more frequently in high mountains than in lowlands.
Consequences for use
Heavy wimmer growth becomes a problem for the woodworking industry, since the wood has a lower dimensional stability and tends to crack. Wimmer occurs more frequently in older fir trees in particular and leads to a decrease in value due to the poor usability. In contrast, spruce or birch is particularly popular for the production of handicrafts or musical instruments , as it guarantees a varied surface structure for the products.
