 wobei jedoch, um keine Schwächung des Blattes am Rosettenrande zu verursachen, je nach der Teilung die radiale Abbiegung jeder zweiten (oder dritten) Durchbrechung d gegen die rosette b hin verlängert wird, wie dies bei d3 angedeutet ist. 



   Durch die zwischen den Durchbrechungen   4   gebildeten, nach   rückwärts   gerichteten

 der in Fig. 1 angedeutet ist, wird von einem Teil des Blattes gehalten, der bereits die Schnittfläche verlassen hat und deren Einfluss entzogen ist. Die Übertragung der treibenden Kraft vom Zentrum des Blattes aus auf den gezahnten Rand desselben findet nach einer   Sehne   statt 
 EMI2.2 
 in der Richtung der   Schnittebene zu   verbleiben, entsprechend   verstärkt   ; ferner erhalten die Speichen f eine gewisse Elastizität, die den Widerstand der Zähne und die damit verbundene stärkere   Anspannung   des Blattumfauges mildert.

   Eine allfällige Abbiegung des Blattes kann auch weniger mehr am   Rosettenrand   als in den zwischen den Durchbrechungen   d   liegenden schwächsten Stellen der Speichen f des Mittelteilses stattfinden, doch werden sich die Speichen infolge der ziehenden   Wirkung   der Kraft immer wieder in die Ebene der undurchbrochenen inneren 
 EMI2.3 
 daher auch der Schuittverlust ein geringerer.

   Die Durchbrechungen bewirken zudem eine lebhaftere Lüftung an den Schnittflächen und Säuberung derselben von   Sägemehl   und verhüten zudem eine   Erwärmung   des Blattes durch seitliche Reibung besser als die der eingangs erwähnten bekannten   Sägeblätter.   Es können deshalb an den Schnittflächen nicht jene durch Reibung erzeugten ausgeglühten blauangelaufenen Stellen enstehen, die eine bleibende Verspannung des Blattes zur Folge haben, sondern es wird das Blatt, auch wenn eine Erhitzung   stattgefunden   hat. in kürzerer Zeit wieder erkalten und die ursprüngliche Form   annehmen.

 however, in order not to weaken the leaf at the edge of the rosette, depending on the division, the radial bend of every second (or third) opening d is lengthened towards the rosette b, as indicated at d3.



   By the formed between the openings 4, directed backwards
 EMI2.1
 which is indicated in Fig. 1, is held by a part of the sheet which has already left the cut surface and whose influence is removed. The transmission of the driving force from the center of the blade to the toothed edge of the blade takes place after a tendon
 EMI2.2
 to remain in the direction of the cutting plane, reinforced accordingly; Furthermore, the spokes f receive a certain elasticity, which alleviates the resistance of the teeth and the increased tension of the leaf circumference associated therewith.

   A possible bending of the leaf can also take place less at the rosette edge than in the weakest points of the spokes f of the central part lying between the openings d, but the spokes will always move back into the plane of the uninterrupted inner part due to the pulling effect of the force
 EMI2.3
 hence the loss of shot is also lower.

   The openings also bring about a more lively ventilation at the cut surfaces and clean them of sawdust and also prevent the blade from heating up due to lateral friction better than the known saw blades mentioned at the beginning. The annealed, blue-tinged spots caused by friction, which result in permanent tension on the sheet, cannot develop on the cut surfaces, but the sheet becomes even if it has been heated. Cool down again in a shorter time and take on the original shape.
