摘要

The fixing gun nozzle (12) has an ejection channel (26) for the fixings (24), e.g. rivets, and incorporates a feeder (32, 34) for a sealant product that is applied to the fixings before they are ejected from the channel. The feeder is made up of feed channel (34) and a distribution ring (32) with a cylindrical inner surface (40) forming part of the ejection channel. The ring's outer surface has a groove (36) leading via radial passages (42) to outlets in its inner surface.
