Abstract
The invention relates to a mixing installation for forming a multi-component product. The mixing installation comprises a material flow line having a first injection inlet, a second injection inlet and a third injection inlet. The third injection inlet is arranged downstream of the first injection inlet and the second injection inlet. The flow line (is provided with a purge downstream of the third injection inlet and arranged directly at the outlet of the third injection inlet, the purge being movable between an active state of purging an upstream part of the flow line and a passive state in which the purge allows the material to flow in the flow line. The invention further relates to an associated control method.

A mixing installation for forming a multi-component product, the mixing installation comprising a flow line of material, comprising:
- a first injection inlet of a first material component;
- a second injection inlet of a second material component, the second injection inlet being arranged downstream of or parallel to said first injection inlet;
- a third injection inlet of a third material component, the third injection inlet being arranged in an injection block downstream of said first injection inlet and said second injection inlet;
- and
- a purge arranged (i) adjacent to and downstream of the injection block and directly at the outlet of said third injection inlet, or arranged (ii) adjacent to and upstream of the injection block, or arranged (iii) in the injection block downstream of said third injection inlet, the purge being movable between an active state of purging an upstream part of the flow line and a passive state wherein the purge allows material to flow in the flow line.
