Heat treatment oven has conveyer belt surrendering products to slower

摘要

A continually operated heat treatment oven receives products which pass through on a conveyer belt system (10) at a steady speed. One section (12) of the conveyer belt system is lowered with respect to the rest. The lowered section is bridged by a roller conveyer (20) operated at a slower speed within a zone having different e.g. temperature or gas content. Products leaving the roller conveyer are returned to the conveyer belt.
