in a method for attaching a anschlussst u00fcckes (7) in the wall of a wasserzuf u00fchrschlauchs the band like wall by a stanzeinrichtung led, in which an opening (4) is applied. in this opening (4), a junction (7) is used and with the sides of the wasserzuf u00fchrschlauchs connected, in particular to a ultraschallschweissvorgang.the attachment of the opening (4), the band (1) between a lochstempel (9) trained sonotrode (10) and a lochmatrize (11) trained anvil (12) of an ultrasonic stanzeinrichtung (no. 2), so that the ausstanzen of butzens (14) from the tape (1) randbereic hey (15) of the opening (4) is fused and sealed.it is in these peripheral areas (15) an optimal strength of the wasserzuf u00fchrschlauchs achieved.
