Thank you to all :)
Video footage in the first video was made in two factories in Poland during installation and testing
Both of them work for a famous worldwide brand that sell low cost forniture,home products,kitchenware and so on
Cots for babies automatic clamp work in another factory in Poland,for the same famous brand

I worked 30+ years in so called "Chair district" here, in North East Italy
Before Berlin's wall fall,our district produced 70% of all solid wood chairs in Europe
I worked for the greatest factory:with branches in France,Serbia,Albania and Bosnia
We had an internal mechanical workshop to made our custom woodworking machines,devices,"patents",automations
So,i did that stuff "in a breeze" :)

Balkan area and East Europe own main raw material: the Beech.So,with the Globalization, main production moved there
but i know some businessman from our industrial district moved to Vietnam to make chairs:East Europe start to be expensive

As Latins said: Dura lex,sed lex (hard rule but this is the rule): always obtain best profit margin
