A roll changer for a web-treating or -processing machine is set up for winding off a working web (A) to be treated or processed from a working roll (A) and for connecting a reserve web (V) from a reserve roll (R2) to the working web (A). The roll changer includes a first mount (1, 4) for the working roll (R1) and a second mount (2, 5) for the reserve roll (R2). A connecting device (10) connects the reserve web (V) to the working web (A). A holding device (21) is arranged downstream of the connecting device (10) along the web for fixing the working web (A). A pulling device (16), is arranged in a path of the working web (A) between the connecting means (10) and the holding means (21) and is set up to pull the working web (A) from the working roll (R1) during the stoppage of the working roll (R1).
