  • the two parallel straight strip sections 8a and 8b as well as sections disposed in the curved edges 7 of the hood are accordingly arcuately curved as shown in FIG. 2.
  • the shield 9 of the hood 4 is essentially provided for stability reasons and has a passage 10 through which the product web 11 is able to enter the container 1 in the direction of the arrow 12.
  • a pull roll 15 is mounted which coacts with the seal strip sections 8a-8c.
  • the straight as well as the curved sections of the seal strip 8 engage the surface of the roll 15 to seal gas or liquid from leaking through the contact area.
  • the area 14 is sealed relative to the environment area 13 in the same way as relative to the container 1 by a sealing apparatus 3' with the parallel seal strip sections 8a and 8b.
  • the curved sections are not illustrated in FIG. I.
  • the product web 11 is introduced, as will be noted from FIG. 1, between the seal strip sections 8a and 8b as well as between the latter and the pull roll into the intermediate chamber 14.
  • the web 11 slides through the intermediate chamber 14 on the surface of the rotating roll 15, in order to enter between the seal strips 8a, 8b on the one hand and the roll 15 on the other hand into the container 1.
  • the straight seal strip sections 8a, 8b or 8a, 8b are of an equal length or are preferably longer than the width of the product web.
  • a single slide film 19, 19' is provided for each of the sealing apparatus 3, 3' illustrated in FIG. 1 on both sides of the central plane M.
  • This slide film is a film sheet 19 which has the framelike shape illustrated in FIG. 3 and which is defined by the two longitudinal edge sections 20, 21 and the side sections 22, 23.
  • a tab 27 is defined by three relieving cuts 24, 25, 26, said tab being connected to the longitudinal edge section 21 along the fold line 28 illustrated in dotted lines.
  • the tab 27 can be shortened, so that a free space is defined between the edge 29 of the section and the edge 30 of the tab 27, as will be noted in FIG. 3. This space can be dispensed with, if desired.
  • the longitudinal edge section 20 as well as the tab 27 each have a plurality of holes 31, 32 parallel to the edges 29 and 30. Both hole rows are provided in the vicinity of the edges 30 or 33.
  • the tab 27 is folded outwardly around the fold line 28 (toward the viewer in FIG. 4), in order to have a further fold line 34 spaced therefrom, the tab thereby being divided into a section 35 and in a section 36 can be dispensed with, and the holes 32 can be shifted to the section 35.
  • the length a of the tab 27 and thus the cutout disposed in the middle of the sheet is larger than the width of the product web 11 and at least equal to the length b of the hood (FIG. 2), which is shorter than the roll 15.
