Powder spray coating device

摘要

The spray coating device has a spray jet (6) with an opening for the powder laden air stream which tapers in cross-section towards the spray outlet (13) relative to one cross-sectional axis and widens in cross-section towards the spray outlet relative to a second perpendicular cross-sectional axis. The opening narrows in cross-section over a threshold section (21), with the widening of the cross-section relative to the second axis provided after this threshold section.
