<p>The device has four-membered prismatic joint gears designed in a form of thrust loops, coupled with one another at a base body (1) e.g. base plate, and comprising a slide ring (4). One of coupling elements (3) includes a guide for the slide ring. The coupling elements are connected with each other over a coupling rod such that the slide ring and a rotary cutting wire i.e. heating wire, are moved opposite to the base body during movement of the coupling elements. The base body is made of timber material or composite material with metal foam.</p> |
