Abstract

Ein solches Messer dient Lösen von an Textilmaschinen aufgewundenen störenden Faserverbänden und setzt sich aus einem Messergriff (1), einem Schieber (3) und einer Messerklinge (4) zusammen. Der Schieber (3) besteht aus zwei Teilen (3', 3"), zwischen denen die Messerklinge (4) liegt und mittels einer, einen Gewindebolzen (21) aufweisenden Klemmschraube zusammengeklemmt wird. Der Schieber (3) ist nicht nur durch umgreifende Seitenflächen (15) gehaltert, sondern stirnseitig in der Arbeitsstellung der Messerklinge (4) (Fig. 1) durch einen Steg (13) und Wandflächen (16) gehaltert. Dadurch wird eine stabile formschlüssige Verbindung geschaffen, so dass grosse Kräfte von der Messerklinge (4) problemlos auf den Messergriff (1) geleitet werden können, so dass das Messer im Vergleich zu bekannten Messern eine wesentlich grössere Einsatzdauer aufweist. Such a knife is used to loosen textile machines wound disruptive fiber associations and consists of a Knife handle (1), a slider (3) and a knife blade (4) together. The slide (3) consists of two parts (3 ', 3 "), between which the knife blade (4) lies and by means of one Threaded bolt (21) having clamping screw is clamped together. The slide (3) is not only due to encompassing side surfaces (15) supported, but in the working position of the front Knife blade (4) (Fig. 1) through a web (13) and wall surfaces (16) supported. This creates a stable positive connection created so that large forces from the knife blade (4) can be easily passed onto the knife handle (1) so that the knife compared to known knives an essential has a longer period of use.
