ABSTRACT:
A pouring head is arranged above a conveyer belt which carries objects to be coated with a coating material being poured from the pouring head in the form of a curtain extending transversely to the direction of travel of the belt. In order to limit the free falling curtain on both sides two rim severing organs are provided on each side of the curtain, one organ above the other, as well as curtain edge-guiding means, one for each severing organ, which are arranged each adjacent the severing organ to which it pertains. The lower severing organs are arranged a short distance above the conveyer belt.
The two severing organs comprise blades for cutting off marginal strips from the falling curtain in two successive stages, thus reducing the width of the curtain to a desired size. The lower severing organ serves mainly to cut off the rim bead being conventionally produced on the curtain where it slides downward on the curtain guiding means, thus preventing the occurrence of undesirably thick marginal zones in the coatings produced on the objects being moved underneath the pouring head by the conveyer belt.
