Once i saw a video of a chinese cuber on youtube, but I was never able to find 
it back.
I remember a small , portable machine with a diesel or tractor drive.
There was a belt or chain conveyor which took the hay or whatever up to 
thecuber wheels which-in may memory -were conically shaped.
I saw sawdust cubes on a fair in Stuttgart some years ago presented by a 
chineese company, but they never answered my mail asking for the origin of the 
cubes.
Would be hard pressed to remember that chinese exhibitors but I still have a 
picture of that young lady representing them...

Who knows about chinese cubers ?
