The invention relates to a holder for those held in openings in a band-shaped magazine Cartridges between a cartridge back and one opposite the cartridge back in his Axial direction moving barrel of a bolt setting device.

It is known to simplify the handling of nolzenselzgcrät magazines for cartridges

use. In particular, tape-shaped 55 fabric are used for this purpose. It has openings 2, which to parts la in such a way

are limited circular that inserted into the opening Cartridges 3 are held in the band 1 so that they do not fall out. The opening 2 but has in the longitudinal direction of the band I after

Magazine straps, the cartridge lies along the two sides of extensions Ib, the width of which, ignition measured with the underside of its base on the carton in the longitudinal direction of the tape, about 15 to tu.schenrücklager and with the top of its base - 20%> the diameter of the circular part la round on the magazine tape against which the other is the opening. Both side edges of the tape are attached to the run of the device. It has been found that notches 4 at equal intervals of, when such cartridges are used, the centers of the cartridges.

Magazine misfires cannot be avoided.

can, and that such misfires also not inserted cartridges shown in side view. here this can prevent the magazine from being inserted into a bolt-firing device.

Magazines known to be either the shape of a straight or circular band. The material used for such ties is in particular Plastic used. When using such

leads, from which the housing 5 can be seen, which iß a handle 6 runs out. The housing 5 has a slot 7 through which the magazine tape 1 can be moved in the vertical direction. from A cartridge retainer 8 is immovable in the housing held, which has an opening 9 for the passage of an ignition needle 10. The cartridge return opposite is barrel 11 of the bolt set / device. This run is like that of a powder-actuated tool It is common to approach the cartridge retainer against a spring (not shown) moveable. F i g. 2 shows the position of the barrel 11 in the rest position. F i g. 3 shows the same arrangement like Fig. 2, but the Lajf 11 as far as possibly been moved against the cartridge retainer is.

Claims (5)

Claims: 1. Bracket of the openings in a band above the cartridge back bearing in its axial Direction moving barrel of a bolt-firing device, characterized in that the OfF- zinband has a conical approach per cartridge on its side facing the barrel, the one corresponding conical opening of the barrel and in a cylindrical bore the shaped magazine held cartridges between 5 cartridge. between a cartridge rear bearing and a counter- The object of the invention is to provide a To create bracket of the type described above, which reduces misfires. According to the invention, this object is thereby achieved openings (2) in the magazine (1) at least one io solved so that the openings in the magazine have a minor extension (2ö) and that that has an extension to the Karst and that that of the Ink return bearing (8) facing the end of the barrel. Cartridge return bearing facing the end of the barrel (II) a protrusion corresponding to this extension one corresponding to this extension Approach (15) has. send approach has. The magazine preferably has 2. Holder according to claim 1, characterized ge 15 zin, which consist of a flat plastic strip indicates that the openings (2) of the magazine can, two - expediently in the longitudinal direction of the Mnonzinhandes - opposing extensions and the sound two enisprccncnuc Approaches. At the moment of ignition, the edge of the cartridge is between the metal cartridge rear bearing and the metallic extensions of the barrel reliably in the one that ensures reliable ignition Location held. That with the previously known magazine tapes in the ignition between Kar Round and barrel material from the magazine tape prevents the position of the cartridges when igniting is completely the same. In order to move the barrel to the cartridge rear bearing back / u opposite to the front surface of the projection (15) of the 30, prevent the cartridge base from being so roughly offset on the barrel that it hits the cartridge retainer in the axial direction that ignition moves the barrel (I Y) dt 1 stop (I6 ) is triggered, the cartridge back is preferably touched at the same time or by at most a few hundcrtstel stock with c-inem stop for a surface of the barrel millimeters earlier than the approach (15) of the provided, which opposite the front surface of the run-up (II) the edge of the Cartridge (i) touches 35 sets of the barrel so far that it touches the stop at the same time or at most a few hundredths of a millimeter earlier than the approach of the barrel in the case of 6. Holder according to claim 5, thereby moving the barrel axially touches the edge of the cartridge, this 4 ° stop can be in the form of strips which, together with the cart table rear viewer, form a guide for the magazine bay.
