., for such "deletions""anyway the contact surface of the individual tooth links on the guide rail · ¥ 4τ® ± --β". small _t which is why the tooth roots wear out very quickly and burrs form on the contact surface, which lock the individual plates and joints and lock the chain itself in the guide groove of the guide rail *

The subject of the invention is a saw chain _? the links of which also consist of two or more thin-walled tabs. ₉ fe «4 soft, mfecy-diqi ob & a
