<p>The invention relates to a device for joining strips of plastic foil material (8a, 8b) so as to obtain at least one foil seam, comprising supply means for supplying the two overlapping strips of foil material to a joining position, as well as joining means made up of at least one assembly consisting of at least one stamp element (31) and at least one anvil element (32) , which at least one stamp element and at least one anvil element are each disposed on either side of the joining position and which can be brought into abutment with each other for the purpose of forming said at least one foil seam. According to the invention, the device is characterised in that abutment means (50) are provided, which, in order to form said at least one foil seam, aid in achieving a full abutment of said at least one stamp element and said at least one anvil element against each other along the entire length of the foil seam to be formed. In this way any deformation of the joining means along the length of the foil seam to be formed is compensated (or prevented), and as a result of the full abutment of the joining means against each other a completely sealed foil seam between the two strips of foil material will be realised, which foil seam will not only be stronger but will also come loose less easily.</p> |
