- Such arrangements which are also referred to as “baffled filter” or “bsffled filter design”, are realized in conjunction with wire knit filters, which, however, are expensive to manufacture and relatively expensive. Also, it is difficult in the manufacturing process to control the uniformity of the knitted wire over the circumference and length of the filter. In addition, the assembly of the baffles means an extra effort.
- the present invention has for its object to provide a filter device and a gas generator available, which allow a good filter use through the use of baffles, but are easy to produce. This object is achieved by a filter device with the features of claim 1 and a gas generator with the features of claim 15. Embodiments of the invention are specified in the subclaims.

- recesses in the sheet metal sections may be formed, for example, as holes and / or as marginal material omissions or indentations. It should be noted that such recesses only serve the directional supply or the directed outflow of gas into or out of the filter device.
- the recesses are due to their number and / or size not suitable to form a filter element itself. It is essentially closed baffles, which adjoin the actual filter material of the filter material web.
- the one or more sheet metal sections constitute separately produced parts which are connected to the filter material web. For this example, they are welded to the filter material web. However, it is also within the scope of the invention that the one or more sheet metal sections are formed integrally with the filter material web.
- the filter device has a metal strip which is punched and / or embossed in the region of the filter material web and / or forms three-dimensional structural elements, so that the filter material web acts as a filter in the wound state.
- the metal strip is formed closed in the region of the sheet metal sections except for the at least one recess for the inflow or outflow of gas and forms a guide plate for the gas to be cleaned. Also, a plurality of such metal strips can be arranged one above the other and wound together.

- FIG. 1 1 in sectional view a first embodiment of a gas generator with a wound filter device according to FIG. 1 B and
- FIG. 12 is a sectional view of a second embodiment of a gas generator with a wound filter device according to FIG. 1 B.
- FIG. 2A shows a rolled, flat-spread filter material web 10 'with rectangular dimensions.
- a hollow cylindrical winding body V is formed, which forms the filter and is shown in FIG. 2B.
- the air passage through the hollow cylindrical winding body takes place in the radial direction, as indicated by the arrows of Figure 2B.
- the filter material web consists of a conventional filter material such as an expanded metal strip. This can be formed in one or more layers. By winding the expanded metal strip, the filter of FIG. 2B is formed.
- expanded metal is generally understood to mean a material having openings in the surface, which have been produced by staggered cuts without loss of material while at the same time stretching.
- the meshes of such a lattice-like material are neither braided nor welded.
- expanded metal is also used.
- FIG. 1A shows a rolled-out, longitudinally spread filter 1.
- the filter 1 has a filter material web 10, which may consist of any rollable filter material.
- the filter material web 10 consists of one or more expanded metal sheets joined together.
- the filter material web 10 is formed rectangular and has two narrow sides or ends 1 1, 12.
- the filter 1 further comprises two closed sheet metal sections 30, 40, which are respectively attached to the ends 1 1, 12 of the filter material web 1. This is done for example by welding.
- the sheet metal sections 20, 30 have the same width as the filter material web 10, so that the filter material web 10 and the sheet metal sections 20, 30 together form an elongated, rectangular filter web.
- the closed sheet metal sections 20, 30 are thus integrated components of the filter 1.
- each recesses 40, 50 are formed in the sheet metal sections 20, 30 of the filter 1 .
- the recesses are formed as a plurality of circular holes 40, 50 extending along the bottom edge of one sheet portion 20 and the top edge of the other sheet portion 30 along a straight line, respectively. As will be explained, these recesses 40, 50 serve the defined inflow or outflow of gas into the filter 1.
- Figure 1 B shows the wound filter 1, which is formed by winding the filter web of Figure 1 A. It should be noted that the sheet metal sections 20, 30 of the filter web be wrapped. During the winding process, a hollow cylindrical winding body forms, which forms the filter 1. Due to the winding also of the sheet metal sections 20, 30, the inner circumferential surface of the hollow cylindrical body is formed by the one sheet metal section 30 and the outer circumferential surface of the hollow cylindrical body by the other sheet metal section 20.
- the offset between the openings 40, 50 results in that shown in FIG. 1 B gas generated inside the hollow cylinder first enters through the openings 50 of a sheet metal portion 30 radially outwardly into the filter, then in addition to a radially outward movement undergoes movement in the longitudinal direction of the filter axis 7 and then leaves through the openings 40 in the outer plate portion 20 in the radial direction of the filter.
- the gas flow is thus directed and compared to a purely radial flow with a longer filter path through the filter 1, so that there is an improved filter use. This is the case both in thermal terms and in terms of particulate retention, since the longer passage of the gas to be cleaned through the filter 1 makes possible, on the one hand, improved heat transfer to the filter and, on the other hand, better particle retention.
- the sheet metal sections 20, 30 thus provide baffles which direct the gas flow through the filter 1 and which are an integral part of the filter 1. With manufacture of the filter from the filter web of Fig. 1A, the baffles 20, 30 are automatically provided and aligned.
- the length of a sheet metal section 20, 30 substantially corresponds to the circumferential length of the hollow cylindrical formed from the filter web
- regions of a sheet metal section 20, 30 do not overlap.
- Length has such that it forms overlapping areas after the winding process.

- the respective sheet metal section 21, 31 has for this purpose adjacent to the filter material web 10 has a smaller width compared to the width of the filter material web 10.
- the recesses 42, 52 for the inflow or outflow of gas are likewise formed on the edge side on the sheet-metal section.
- the recesses 42, 52 are provided as a zigzag edge with corresponding notches.
- Edge-side recesses 41, 51, 42, 52 according to FIGS. 3A, 3B, 4A, 4B have the advantage of a relatively simple production.
- FIGS. 5A, 5B in the sheet-metal sections 23, 33, similar to the embodiment of FIGS. 1A, 1B, circular holes 43, 53 are formed, each extending along a line extending in the longitudinal direction of the sheet-metal section.
- a centrally arranged row of holes 43 is provided in one sheet metal section 23.
- two edge rows of holes 53 are provided in the other sheet section 33. This ensures that the gas flow in the filter branches and flows, for example, from the centrally arranged holes 43 both upwards and downwards to the holes 53.
- FIGS. 6 to 10 show alternative embodiments of the semifinished products for producing wound filters according to the invention. It should be noted in advance that in Figures 6 to 10, the lateral closed sheet metal sections are not shown separately. However, these are also present in these embodiments, but formed integrally with the actual filter material web. The training can be carried out according to the figures 1A to 5B.
- a section of the unrolled filter qualifies as a filter material or as a gas guide plate as a function of whether filter structures are formed in the semifinished product or not.
- the gas guide plates forming sheet metal sections no filter structures are provided. Rather, it is closed sheet metal sections, which have only recesses for inflow or outflow of gas.
- a perforated plate 13 with punched holes 131 is provided as semifinished product for producing a wound filter, which are formed, for example, but not necessarily, round.
- the punched holes are formed only in the region of the filter material web 13, not in the (not shown) closed sheet metal sections.
- the filter material web is formed as a perforated plate 14 with punched holes in the form of triangles 141. Other form punching are of course also possible.
- the filter material web 15 has an embossed structure with a wall thickness change ⁇ t in the sheet-metal plane direction. Due to the change in wall thickness arise in the wound sheet metal channels for gas flow in the filter.
- the filter material web 16 is designed as a structural sheet having three-dimensional miniature structural elements 161. These can be formed on one or two sides, drawn, profiled, rolled, hydroformed, etc.
