Definitions
- the invention relates to a nozzle arrangement and a method for forming strands for viscoelastic compositions according to the preamble of claim 1 and the preamble of claim 17.
- Nozzle arrangements for strand formation for viscoelastic masses, in particular polymers, dough masses etc. are known per se. As a rule, they are equipped with several similar nozzle channels arranged parallel to one another, which extend through the nozzle from an inlet opening to an outlet opening, the respective nozzle channels along the axial conveying direction of the mass, an inlet area at the upstream end of the nozzle channel and an outlet area have at the downstream end of the nozzle channel.
- the inlet openings are arranged adjacent to one another.
- the invention is based on the object of minimizing such material stresses in viscoelastic materials when they are converted into material strands and of the energy required for the strand formation or the pressure difference required for this, i.e. to reduce the nozzle resistance.
- the cutting edges can form an angle other than 90 ° to the axial conveying direction of the material. You can, for example, at an angle of about 30 to 60 ° to the conveying direction of the material. However, an acute angle is preferred. The more acute the angle to the conveying direction, the greater the length l_s measured along the conveying direction of the region in which the material is cut in the radial direction perpendicular to the conveying direction, for example from radially outside to radially inside.
- the radially outwardly flowing areas of the material are then cut, for example, first, while the radially inwardly flowing areas of the material are cut later. Then, however, the radially outer areas already had time to reduce their stresses that were entered into the material during cutting. Through the cutting process, a total of fewer tensions are thus introduced into the material distributed over the nozzle channels than would be the case with cutting edges running at right angles to the direction of flow (simple "cutter" principle).
- the outlet area from the nozzle channel inner area to the outlet opening is widened in a bell-like manner over a length LA along the axial conveying direction F, the widening angle of the outlet widening along the axial conveying direction, which is measured between the axial conveying direction and the inner wall of the channel outlet area, preferably increasing continuously.
- the increase in the widening angle along the axial conveying direction can increase continuously, e.g. the widening angle increases from 0 ° inside the nozzle to 90 ° at the downstream end of the nozzle body.
- the widening in longitudinal section can e.g. follow a circular arc whose radius of curvature RA is greater than the radius R
- This curved widened outlet area replaces the edge of conventional outlet openings by a curved continuous transition from a vertical tangent in the interior of the nozzle channel to an oblique, in extreme case horizontal, tangent at the downstream end of the outlet area.
- the viscoelastic mass is pressed through it by means of a pressure gradient ⁇ p between the upstream end and the downstream end of the nozzle arrangement.
- FIG. 6 is a sectional view through another prior art nozzle channel along the axial product conveying direction F;
