The type already described is valid by the fact that at least the one clamping plate carries one or more permanent magnets, the old the other clamping plate a magnetic conductor ■ eg form. Such a design makes the sewing table Magnets arranged on a plate are superfluous. The two clamping plates «Earth directly against each other and against those in between Well pressed and not indirectly through Tightening the upper clamping plate held together against the sewing table top »The template drive remains from the Clamping force of the clamping device unaffected, de the magnetic forces only act between the clamping plates. the The clamping force of the clamping device can therefore be as desired without any adverse effects on the stencil drive be made big · Different by corresponding Ulahl eterker permanent magnets and / or the respective intended number of dieeer (Blessed can the closing force the im can be optimally adapted to individual given requirements. In addition, the permanent magnets are reinforced there take effect where particularly high loads occur during sewing. For example, one becomes functional Provide more and / or stronger magnets along curved parts of the sewing path than along straight lines Sections of the sewing path

It is useful to manufacture the lower clamping plate from magnetically highly conductive material and in edge areas to let in several permanent magnets on the upper clamping plate. Preferably, the upper clamping plate is also with a their contour following, provided downward, toothed web. The bridge transmits the closing force in the immediate vicinity of the sewing path on the sewing material, which is of particular advantage for safe clamping let. It also acts as a considerable reinforcement of the upper clamping plate, so that it is relatively out of proportion thin material can be made. The teeth on the lower edge of the web contributes to an immovable
