bars

11,12.

In the zone away from

bar

11,12, thin slice 10 is provided with recess in its narrow side or side, is used for thin slice 10

bands

14,15 connected to one another are pressed into this

recess.Band

14,15 preferably is attached on two narrow sides of thin slice 10 and under elasticity and/or plastic deformation, is pressed in the recess 13 of thin slice 10, makes their that elasticity and/or plastic deformation take place, and forms with thin slice 10 simultaneously to be rigidly connected at least.Before attached band, with thin slice 10 with the expectation pitch arrangement in device, make recess 13 be in alignment with each other.In addition, be provided with laminar side part 16, it is corresponding with thin slice 10 and be provided with the device 17 that is used for

fixing bar

11,12 in shape.Device 17 for example can be the bellmouth that bar 11,12 is assemblied in wherein.

Band

14,15 also extends the part 16 as far as the side, makes these bands and thin slice 10 and

bar
