this embodiment of the 4 is annular and/or conically designed Fig. 6 the nozzle. It [...] but this is also the, the nozzle design interrupted. Thus gas jet arrangement 39 into a plurality of gas nozzles undergo division, which are arranged along the periphery of the separation zone, for example, 11. Even includes providing two gas nozzles antagonistic cross-shaped, substantially the same result as the sectional view of the sectional view 4 Fig., [...] corresponds to the.

The gas nozzle 9 opens into the 6 gas nozzle exit , from which the gas can escape.

In a preferred way the gas in the free separation region 11 enters This. Even mass inlet 2 enters the mass 4 in the form of a free from the from. According to the present execution of the 9 11 arranged in the immediate vicinity of the separation zone is gas nozzle exit.

The mass inlet 4 is 25 formed substantially by a jacket tube, which extends one or several parts 11 and up to the separation region for mass outlet 38. Direction 25 has a tapered region 19 on the jacket tube 11 separating region. Also the outer wall 26 of the jacket tube is obliquely or conically designed direction separating region 25. The outer wall 26 forms a first wall of the gas nozzle 6 in this area is formed by the inside of the second wall 27. The nozzle bowl. The nozzle bowl 25 connected with the jacket tube 27 and has to this a cavity is on, the is the fundamental element of the gas nozzle 6.

To control and regulation of the gas pressure may be adjusted in accordance with the compressor a buffer memory, a pressure regulator, a pressure gauge, a Air heating device and/or a flow controller be provided. Through these control options the gas flow can be precisely controlled and/or regulated. With the arrangement against each other at conical nozzles arranged by dynamic effects also directed nozzles or a part of the gas jet in discharge direction can 3 be deflected of the gas jet. In order to avoid the negative effect of uncontrolled deformation of the mass body 1 is, in such a case an accurate adjustment of the control and/or control parameters of the gas flow necessary. Depending on the geometrical configuration of the gas nozzle 6 of the gas mass flow is therefore to choose in such a way that the in discharge direction in the region of the mass body has a speed 3 deflected low gas mass flow , the uncontrolled deformation of the mass body effected no. Advantageously, the speed is only slightly larger in the region of the mass body in discharge direction of the deflected gas mass flow , equal to or less than the output speed of said mass body 1.

So of the gas pressure can be approximately 0.1 to 3.5 bar in the pressure feed line 12 according to one embodiment. The 0.1 to 125 is in this case of about volume flow of litres per minute and per gas nozzle variable. The opening time of the valve, during which the gas nozzle is 6 flows through, can be between 0.01 and 2 seconds.

Even the gas nozzle 6 has, similar to the distribution chamber 13, on a certain void volume. This void volume is used, in particular, the distribution of the pressure. In the illustrated embodiments, for example, can be 9 gas nozzle exit gap width of the The 0.1 to 0.8 mm between. In particular, the required gap width is a function of the viscosity of the mass to be cut.

The gas jet is preferably directed transversely to the discharge direction 7 2 3 direction mass.

90° to 45 °, for example, angle of this are convenient. This angle is measured between the direction of the gas jet 9 and the discharge direction 7 at the 3 gas nozzle exit. Is Preferably, the gas jet, as represented in the direction of movement of the mass inclined in Figures.
