Abstract

The present invention relates to a method for providing K-E ammunition, such as sub-calibre arrow-type projectiles (2), with skidding plastics driving bands (11) acting as barrel seals, by virtue of the fact that the driving bands, before being fitted, are provided with at least one cut (13) running through their casing surface, which cut (13) makes it easier for the driving band to be fitted into a specifically designed groove (8). The invention also includes the finished driving band.

Description

517 164 l uppkomna direkt på den verkande höga krutgastrycket varvid gördeln helt enkelt kollapsar. 517 164 l arising directly at the acting high gunpowder gas pressure whereby the belt simply collapses.

I enlighet med föreliggande uppfinning föreslås nu istället ett mekaniskt mycket enkelt men i ammunitionssammanhanget ytterligt radikalt grepp nämligen att gördeln genom ett på lämpligt sätt utformat delningssnitt tvärs över dess mantelyta öppnas så att den lätt kan tvingas isär och träs över den aktuella styrvalken samtidigt som denna kan ges full dimension. Väl nedförd i sitt spår innanför styrvalken får gördeln återta sin ursprungliga form. Det är även tänkbart att efter monteringen limma eller svetsa ihop gördeln längs delningssnittet men överraskande nog har det visat sig att detta är onödigt.In accordance with the present invention, it is now proposed instead a mechanically very simple but in the ammunition context extremely radical grip, namely that the belt is opened by a suitably designed dividing section across its mantle surface so that it can be easily forced apart and threaded over the current guide wall. given full dimension. Once lowered in its groove inside the steering column, the belt may regain its original shape. It is also conceivable to glue or weld the belt along the dividing section after assembly, but surprisingly it has been found that this is unnecessary.

Trots att gördeln alltså är delad även under utskjutningen har det visat sig att det inte förligger någon som helst risk för att gördeln skall kollapsa.Despite the fact that the belt is thus also split even during the launch, it has been shown that there is no risk whatsoever that the belt will collapse.

Delningssnittet kan ha olika utformning men snett anlagda snitt torde vara att föredra även om rent axiella raka snitt även torde vara tänkbara.The pitch section may have a different design, but obliquely arranged cuts should be preferred, although purely axial straight cuts are also conceivable.

Uppfinningen har deñnerats i de efterföljande patentkraven och den skall nu något ytterligare beskrivas i samband med bifogade figurer.The invention has been defined in the following claims and it will now be described somewhat further in connection with the accompanying figures.

Av dessa visar fig 1 en sidprojektion av en pilprojektil förberedd för montering av gördeln samt en gördel som är klar för montering fig 2 en snedprojektion av en gördel enligt uppfinningen samt fig 3 den färdiga projektilen.Of these, fi g 1 shows a side projection of an arrow projectile prepared for mounting the belt and a belt ready for assembly fi g 2 shows an oblique projection of a belt according to the invention and fi g 3 the finished projectile.

Den på figurema visade kompletta projektilen l innefattar själva pilprojektilen 2 som har en främre spets 3 och ett bakre fenstyrverk 4. Den är i sin tur om- given av en längs snittet 6 delad drivspegel 5. Drivspegelns 5 olika delar, som företrädesvis är minst 3, hålles samman av ett främre brytband 7. I driv- spegelns bakre del finns ett gördelspår 8 som på vardera sidan omges av en främre styrvalk 9 och en bakre styrvalk 10.The complete projectile 1 shown in the figures comprises the arrow projectile 2 itself which has a front tip 3 and a rear fin control unit 4. It is in turn surrounded by a drive mirror 5 divided along the section 6. The various parts of the drive mirror 5, which are preferably at least 3 , is held together by a front breaking belt 7. In the rear part of the drive mirror there is a belt groove 8 which is surrounded on each side by a front guide roller 9 and a rear guide roller 10.

I gördelspåret 8 skall således en gördel ll av den på ñg 2 visade typen monteras. Gördeln ll förberedes för monteringen genom att dess mantelvägg 0 Q Q U Il O I O O OO I O O O .O 517 164 3 genomskäres längs minst ett relativt dess bredd företrädesvis snedställt snitt 13, som alltså öppnar gördeln så att den på det sätt som antyds på fig 1 kan tvingas isär och träs över den bakre styrvalken 10 och ned i det därför avsedda ____ __ spåret 8 varefter de båda snittytoma 13a resp 13b av materialets elasticitet :_ .z återförs till anläggning mot varandra uppstyrda som de är av gördelspårets 8 kanter. Sedan gördeln monterats kontrolleras att den kan rotera fritt i sitt spår varefter projektilen är klar för utleverans. ' -- -~Thus, a belt ll of the type shown on ñg 2 shall be mounted in the belt groove 8. The belt 11 is prepared for mounting by cutting its casing wall 13 along at least one section 13, preferably inclined relative to its width, which thus opens the belt so that it can be forced apart in the manner indicated on fi g 1. and is threaded over the rear guide wall 10 and down into the groove 8 intended for this purpose, after which the two cutting surfaces 13a and 13b, respectively, of the material elasticity: After the belt has been mounted, it is checked that it can rotate freely in its groove, after which the projectile is ready for delivery.
