Abstract

See full text

The invention relates to an improved blowing nozzle, in particular for stretching systems, which is characterised by the following features, inter alia:

    the nozzle box (5) is divided in its longitudinal direction (L) into at least two regions, specifically a first longitudinal region (LB1) closer to the inflow side (7) and a second longitudinal region (LB2) that is subsequent and/or downstream and/or further away from the inflow side (7),the first longitudinal region (LB1) is convergent or comprises at least one convergent portion in which the height (H) between the lower face (11) and the upper face (15) is smaller than the height (H1) in the region of the inflow side (7) as the distance from the inflow side (7) increases, andthe second longitudinal region (LB2) is divergent or comprises at least one divergent portion in which the height (H) between the lower face (11) and the upper face (15) is greater than the height (H) at the end of the first longitudinal region (LB1) and/or at the beginning of the second longitudinal region (LB2) as the distance from the inflow side (7) increases.
