Title:
DEVICE FOR EXTRACTING POWDER
Document Type and Number:
WIPO Patent Application WO/2004/104556
Kind Code:
A1
Abstract:
The invention relates to a device for extracting powder, said device comprising a vertical pipe (1) and an adjacent, also vertical, slide that can be lowered so that a gullet (5) slips into an extraction opening (12). A flap (15) can be used to temporarily direct powder towards the gullet (5) and to fill the same, without the slide (4) or the flap (15) disturbing the flow in ordinary time nor retaining any powder, which could result in the measures being distorted. Especially the flap (15), the gullet (5) and the overhang (2) have sharply inclined sides (6, 8) on which the powder can only slide.
