ABSTRACT:
The most important heat-sealing parameters must be able to be adapted to different conditions of use in a simple and accurate manner. This is accomplished by the hot air temperature, on the one hand, and the amount of hot air, the speed of rotation of the pressing rollers (8, 9) and/or the pressing pressure of the pressing rollers (8, 9), on the other hand, being able to be controlled via controllers (41, 37, 24, 29), wherein a basic setting of the set points of these controlled variables is performed as a function of material- and/or application-specific characteristics, and by the position of the hot air nozzle (16) in terms of height (H), distance (A) and/or of the oncoming flow angle (.alpha.) with respect to the roller gap being able to be set by motor operators (18, 19, 21) as a function of the intended use and/or the thickness of the workpiece.
