The feed-out device is arranged on a spreader for sand, salt, etc., and at the sloping vessel feed-out opening is arranged a gap blade, between when and a bottom plate or roller material can pass. The gap blade (4) is fixed to links (8) at opposite ends articulated around a rotary point (1) and suspended at the top (3) in a chain (2) or wire. The gap blade limits the outflow of material between it and a bottom plate (5) or roller. |
