Embodiment Construction

[0014] The drawing shows a tube bag machine 10 according to the invention for producing tube bag packages 1 , in particular filled with food. Hose bag packaging 1 ( figure 2 ) each have a lower transverse seal 2 , an upper transverse seal 3 and at least one longitudinal seal 4 . The tube bag pack 1 is formed from a packaging material web 11 which consists of a heat-sealable material and is stored in the form of a supply roll 12 on a shaft 13 .

[0015] The tube bag machine 10 has a tube forming device 15 which comprises a forming shoulder 16 and a forming tube 17 which is connected to the forming shoulder 16 and which is in particular circular in cross section. In order to form the packaging material tube 5 from the packaging material strip 11, the packaging material strip 11 is drawn onto the forming shoulder 16 and placed around the forming tube 17, wherein the packaging material strips 11 overlap each other in the longitudinal direction The edge area of ​​the vertical se...

Abstract

The invention relates to a tubular bag machine (10) having a tube forming device (15), comprising a forming shoulder (16) and a forming pipe (17) for forming a packaging material tube (5) made of at least one packaging material web (11), a vacuum-assisted take-off device (25) in the form of endless recirculating belts (26, 27) in the region of the forming pipe (17), a storage roll (12) for storing the packaging material web (11), wherein a partial length of the packaging material web (11) is intermediately stored in a buffer device (38) between the storage roll (12) and the forming pipe (17), and wherein the buffer device (38) comprises at least one dancer roll (43, 44) having a force applied thereto by means of a tensioning device (48) and applying a tension to the packaging material web (11) in the region of the buffer device (38), which tension acts at least partially unto the region of the take-off device (25). According to the invention, the force application of the at least one dancer roll (43, 44) can be modified by the tensioning device (48) as a function of the operating state of the take-off device (25).

Description

technical field [0001] The invention relates to a hose bag machine and a method for operating the hose bag machine according to the preambles of the independent claims. Background technique [0002] Such a hose bag machine and such a method for operating a hose bag machine are already known in practice, wherein in particular food products such as potato chips, sauces etc. are packaged in hose bag packaging by means of the hose bag machine middle. Such a tube bag machine has a tube forming device with a forming shoulder and a forming tube, onto which the flat packaging material web is drawn and thus formed into a packaging material tube. A longitudinal seam and an upper and a lower transverse seam are provided on at least one longitudinal side in the region of the forming tube on the packaging packaging material tube. Pulling belts arranged on both sides of the forming tube for conveying the packaging material strip or the packaging material hose are operated with a negativ...
