Abstract: An applicator is utilized in applying a thermoplastic composite filament to a mandrel so as to form a structure. The filament and the surface of the mandrel are caused to move simultaneously and in a common direction relative to the applicator so that the filament is continuously fed from the applicator into engagement with the surface of the mandrel. At least one stream of heated fluid is applied to the filament so that it impinges thereon not only at location preceding the location of the applicator, but also along the length of the filament to and beyond the applicator and up to and including the region where the filament first comes into contact with the mandrel. At the same time a stream of heated fluid is applied directly to the surface of the mandrel within that region so that the mandrel is heated prior to being contacted by the filament.

Abstract: A keg capping machine primarily for use with beer kegs having protruding neck portions upon which flexible plastic caps are to be fitted. The machine has a capping head attached to the lower end of an inclined cap chute which is attached on its upper end to a cap storing hopper. The capping head has horizontal flanges on its bottom edge which serve as stops and guideways for caps sliding down the chute. The neck of a keg which is carried along a conveyor moves between the guideways and engages the lower portion of a cap forcing it through the capping head. A cap driving rocker within the capping head is employed to force the cap down tightly onto the neck of the keg.
