摘要： The invention relates to a tubular bag machine and to a method for operating a tubular bag machine (01) for the continuous production of tubular bags (20), which are filled with a mixture of liquid and solid filling components (29, 30). A formatting device (18), by means of which the bag shape of the tubular bag (20) open at the top seal is formatted, is disposed below the wiper device (16), the formatting device (18) comprising at least two formatting elements (19), which are contacted on the outer side of the film tube (34) and are displaced between an open position and a formatting position. The horizontal distance between the formatting elements (19) is larger in the open position than in the formatting position. The formatting elements (19) are moved to the open position before and/or while filling the tubular bag (20) with filling material (29, 30). The formatting elements (19) are moved to the formatting position while and/or after filling the tubular bag (20) with filling material (29, 30) and before producing the top seam to remove air from the air bubble (32) in the top area of the tubular bag (20) via filling material components (29, 30).

摘要： The embodiments of the invention relate to a method for creating a force for a welding jaw of a vertical tubular bag machine. The welding jaw is moved back and forth along a path to strike a second welding jaw moving in the opposite direction. A tubular film is compressed between the second jaw and at least one sealing surface of the welding jaws, to weld the tubular film by ultrasonic vibrations applied thereto via the sealing surface at an applied pressure under a sealing force (Fs) within a sealing time (ts). The sealing force (Fs) is predetermined by a control unit such that the sealing force (Fs) runs along a sealing force curve within the sealing time (ts). The sealing force curve has a first relative sealing force maximum (Fs1) and at least one second relative sealing force maximum (Fs2), wherein (Fs1) is lower than (Fs2).
