Abstract

En føring-knast for en start- eller vindusfres er anordnet ved den øvre ende av ledekilen. En oppbakkingsskulder er anordnet for å virke mot fresens tendens til å virvle. En konus er anordnet for bruk til å føre fresen mot foringsrøret for å skjære ut vinduet. Knasten er utformet til å slite av en føring for vindufresen eller starter- fresen i steden for å bli frest bort. Som en følge av bruken av fresen, blir de øvre seksjoner av ledekilen beskyttet fra fresen. I sin turn blir hull eller andre fremspring som er anordnet for senere gjenvinning av ledekilen funksjonelle for slik gjenvin- ning etter fullføring av freseoperasjonen for vinduet.
