An arrangement (1) for the treatment of a material (7, 8; 7′, 8′; 7″, 8″; 18) having at least two layers of material by an ultrasonic device (2) having an ultrasonic horn (3) arranged in conjunction with an abutment (5), in conjunction with which the material (7, 8; 7′, 8′; 7″, 8″; 18) is positioned in a gap (6) that is defined between the ultrasonic horn (3) and the abutment (5), and the ultrasonic horn (3) and/or the abutment (5) is/are so arranged as to be capable of displacement to permit adjustment of the size of the gap (6), for which purpose the arrangement (1) also includes a control unit (13) for the regulation of the size of the gap (6) dependent on the energy supplied to the material in the course of the treatment. The arrangement further includes a detection device (16) for the determination of at least one predetermined dimension (b1; d1; b3) of the material (7, 8; 7′, 8′; 7″, 8″; 18), in conjunction with which the control unit (13) is arranged for the regulation of the size of the gap (6) dependent on at least the dimension (b1; d1; b3). |
