METHOD FOR AGEING A PACKAGE OF STONES
Document Type and Number:
WIPO Patent Application WO2004078439
Kind Code:
A3
Abstract:
A device (1) for ageing a package of stones comprises a cage (24) for locking the package of stones with play being present. For the purpose of the ageing process of the stones, the cage (24) is suspended in a frame (30) wich is rotatable about a rotation axis (55).During a rotary movement of the frame (30) and the cage (24), the stones collide against each other, and outer stones of the package additionally collide against plates (21,22,23) of the cage (24).The play between the package of stones and the cage (24) is chosen such that the stones have space to move on the one hand , and that the position and the orientation of the stones in the package are maintained on the other hand .Consequently, after the ageing process has finished, the stones can be removed from the ageing device (1) as an ordered package.
