over the width of the spunbonded fabric 9 that is to be produced at the bottom side the filaments 8 that were generated inside the pivoting unit leave said pivoting unit 1 by way of a curtain the pivoting unit 1 is pivotably supported inside bearings 16 for reasons of simplification the adjustment in vertical direction is not shown the melt that is necessary for the production of the filaments 8 is supplied to the apparatus by the melt feed line 17 through a rotary leadthrough 18 1 this allows for the pivoting action of the pivoting unit during operation during this process it is not the continuous pivoting motion of the pivoting unit 1 that is the focus but rather the adjustment to a required product when the production process is started the rotary leadthrough 18 1 that is depicted here allows for pivoting action of the pivoting unit around a swivel axis the melt feed line 17 has a further rotary leadthrough 18 2 in order to allow for the vertical adjustment as provided in an improvement according to the invention and as represented in fig1 as well the blowing air for the blowing apparatus is supplied by a blowing air feed 21 an elastic connection 20 and the blowing air line 19 in the alternative to the rotary leadthroughs 18 1 and 18 2 an elastic connection 20 in this instance allows for a degree of freedom of the pivoting unit 1 other possibilities of supplying the melt and the blowing air to the pivoting unit 1 that deviate from the above and are alternative relative to the depicted embodiments are also known in the art and fall within the scope of the present invention for example it is.
