Tunnel oven for sintering and burning rotationally symmetrical objects has transport unit with disc wheels aligned spaced from each other across longitudinal direction for holding and turning articles

摘要

The articles are moved through the tunnel oven by a transport unit (11) having two disc wheels (13) aligned spaced from each other across the longitudinal direction of the oven and each wheel having an opening to hold the article (15). The wheels can be coupled to a rotary drive for an at least partial rotary movement. The individual transport unit consists of two spaced disc wheel combinations each with two adjoining interconnected disc wheels.
