Abstract
Abstract An arrangement for applying an adhesive medium, particularly for leather and shoe articles, has an adhesive medium applying nozzle and a nozzle needle member arranged to close and to open the nozzle. A driver connects one end of the nozzle needle member with a driving unit which includes at least two selectively actuatable driving devices formed with individually adjustable displacement elements so that they move the nozzle needle member selectively over different adjustable strokes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
An arrangement for applying an adhesive medium, particularly for leather and shoe articles, comprising an adhesive medium applying nozzle; an elongated nozzle needle member arranged to close and to open said nozzle and having an end portion; driving means for driving said nozzle needle member; a driver which is displaceable in the longitudinal direction of said nozzle member and arranged so that said end portion of said nozzle needle member is coupled with said driving means via said driver, said driving means including at least two selectively actuatable driving devices which are formed with individually adjustable displacement means so that they can move the nozzle needle member over different adjustable strokes.
