Device for the dust-free pulling of bag-like

Me hiring 'relates to a device for gum dust-free filling sta, practicing bulk goods in sack-like containers »in particular sauna filling of bags with standard valves, if necessary, Bags and similar containers with finely divided granular or free-flowing, solid materials} - which are particularly light disintegrate into dust «! Secrete or collect dust, absr also from as good as dust-free goods *

When filling, especially of automated filling, such goods "has so far been avoided some dust around the plant through very fine portions of the material not au * This is always particularly großj if the measured product to already very fine, light _s voluminous and / or or. strong air or gas and · it always leads to contamination of the rooms and filling systems as well as undesirable material losses · it is always at least unpleasant if not even harmful to health for the operating personnel.

The dust was investigated by zn avoid or minimize su _t that such goods are not filled into open containers or bags, but this so-called valve bags of diverse construction or the like "Kau usually automatic or semi-automatic makes use of is cli working filling with more or Filling nozzles that can be inserted less tightly into the valves or filling hoses of the bags · However, removing the air brought in with the filling material always causes certain difficulties, because the valves are? in order to ensure a tight seal of the filled sack, designed in the Hegel in such a way that after filling the sack close or "squeeze off" the brought in dead yourself.
