A method for operating a tubular bag machine having a film web capable of unwinding from a supply reel, a shoulder for forming the web into a film tube, a take-off unit serving to move the tube, a longitudinal sealing device for welding the tube parallel to its transport direction by a longitudinal seam, a sealing device with jaws for producing transverse seams in the tube, a separating element for separating finished tubular bags from the tube, the machine being accelerated in a positive acceleration phase from an initial speed to a target speed when starting or being decelerated in a negative acceleration phase from the target speed to a final speed for stopping, wherein, in the positive acceleration phase and/or in the negative acceleration phase, at least one sealing parameter of the jaws for producing tubular bags changes as a function of the conveying speed of the web.
