Definitions
- the invention relates to a band-shaped loading strip for powder-operated setting tools, with receptacles for a propellant charge protruding from the band having a flat side of the recesses and a truncated cone-shaped outer contour, and an annular gap open to the opposite flat side of the band for receiving a collar of the recess of the band to this flat side closing bottom part, wherein in the longitudinal direction of the band a plurality of recesses arranged one behind the other at equal intervals are provided.
- a loading strip of the aforementioned type is known from EP-A-0 273 777.
- a considerable disadvantage of this known charging strip is that the volume composed of the cavity of the receptacle and recess can only hold an insufficient amount of propellant charge, which results in driving energy which is too small for the large number of applications. Furthermore, the known primer causes high costs due to the large amount required.
- the invention has for its object to provide a charging strip that can accommodate a large amount of propellant charge to achieve high driving energy and is suitable for the use of an economical primer.
- the object is achieved in that an eccentric opening for an ignition charge is provided eccentrically between the annular gap and the recess toward the flat side of the band to be closed by the base part.
- the eccentrically arranged primer is characterized by the fact that only a small amount is required, which leads to low costs and to a reduced contamination of the setting tool.
- the primer is introduced into the recess, for example, by filling the required quantity into the recess as a moist mass.
- the igniter and propellant charge are covered by the subsequently attached base part.
- the direction and the amount of the eccentricity of the recess are advantageously the same for all the recesses arranged one behind the other, the recess being able to be offset eccentrically in the longitudinal direction or laterally to the longitudinal extent of the band. This ensures reliable activation of the primer by the ignition device, which is stationary in the setting tool.
- the resultant arrangement of a plurality of cutouts when inserting the primer has an advantageous effect in that the loading strip or the insertion device only has to be given a feed movement in one axis.
- the volume of the recess preferably corresponds to 0.002 to 0.01 times the sum of the volume of the recess and cavity of the receptacle. A cut-out of this size allows an igniter to be inserted, which ensures reliable combustion of the entire propellant charge in conjunction with a small amount of igniter material.
- the band and the receptacle are integrally formed from plastic.
- the advantages of this design are, above all, the low costs due to the material and manufacturing.
- the bottom part suitably consists of metal, for example brass or steel.
- the loading strip 1 shown in Fig. 1 consists of a band 2 and from the one flat side of the band 2 projecting, spaced apart in the longitudinal direction of the band 2, cup-like receptacles 3 according to Fig. 2.
- the longitudinal edges of the band 2 are with recesses 4 for engagement a transport device of a setting device.
- the cavity 3a of the receptacles 3 opens towards the hinge side into a recess 2a in the band 2 that is open to the outside.
- a recess 2c eccentric to the axis of the recess 2a between the annular gap 2b and the recess 2a.
- the inner contour of the recess 2a protrudes in the region of the recess 2c into the recess 2a, which is circular in cross section.
- An opening 2d creates a connection between the recess 2c and the recess 2a.
- the cavity 3a and the recess 2a serve to receive a propellant charge 5, for example in powder form.
- An ignition charge 6 in the form of a moist mass can be introduced into the recess 2c in a simple manner.
- the recess 2a and the recess 2c can be closed to the outside by means of a base part 7, a circumferential collar 7a snapping into the annular gap 2b for holding purposes.
