Definitions

  • the invention relates to a method for producing (tobacco) bag packages with Velcro pieces for fixing a tab in the closed position and the other features in the preamble of claim 1. Furthermore, the invention relates to a device for carrying out the method.
  • Pouches made of film are known with a tab, in particular tobacco pouches with a closure tab or winding tab designed as continuation of a pouch rear wall, and with hook and loop fasteners for fixing the tab in the closed position on a pouch front wall or on a pouch back wall (US Pat. EP 1 215 973 B1 ).
  • the strip-shaped Velcro pieces are positioned in this known embodiment of a (tobacco) bag in transverse relative position to each other on the tab on the one hand and the bag wall on the other.
  • a first hook and loop fastener on the inside of the flap and a second hook and loop piece are attached separately to a bag wall position corresponding to the closed position of the flap.
  • the Velcro pieces are permanently fixed by gluing on the tab or on the bag wall. The production of the so-formed bag packages is complicated and often imprecise in terms of the positioning of the Velcro pieces.
  • the invention has for its object to avoid the above problems in the production of packages with Velcro pieces for fixing a tab and in particular to improve the attachment of the Velcro pieces in an exact relative position.
  • the inventive method is characterized by the features of claim 1.
  • the particular rectangular or square Velcro pieces are therefore first connected with their adhesive coating, in particular with their Velcro coating into a unit of two pieces.
  • This unit is then either applied to the (closure) tab or to the packing or bag wall and bonded thereto by gluing or otherwise.
  • This process step is performed with the package open or the bag open. Thereafter, the tab is brought into the closed position, wherein, depending on the position of the unit from the connecting pieces, the free side of one of the connecting pieces of the unit is connected either to the tab or to a packing or bag wall.
  • the Velcro pieces are preferably separated from a strip of material, wherein according to the invention two continuous Velcro strips in the region of the Velcro coating are adjacent to each other and are connected by pressing against each other. From this double strip then appropriate units of (two) Klett pieces are separated and fed to a pack.
  • the double strips of two Velcro strips can be made from single, continuous Velcro strips by merging and pressing together directly in the processing area.
  • a strip of material with at least two juxtaposed and parallel Velcro strips.
  • This starting web is folded along a line between adjacent Velcro strips, such that the two Velcro strips can face each other and be joined together by compression.
  • the material web or a carrier tape for the (two) Velcro strips is preferably provided with a weakening line, so that the material strip can be severed during the assembly of the Velcro strips.
  • a separation of the unit after attachment to the package or the bag, wherein the relative position is selected so that the carrier is severed during the opening process and associated separation of the Velcro pieces.
  • the invention relates to devices for producing the Klätinnism and for transmitting the same on (tobacco) bag.
  • the preferred field of application for the innovations are methods and apparatus for producing foil pouches, in particular in the form of tobacco pouches 10 for receiving a portion of tobacco.

  • the closure seam 16 is designed such that it can be easily opened when the package is put into use.
  • the tobacco bag 10 has a tab 17 which is formed as an extension of the bag rear wall 13 and thus as part of the one-piece foil blank.
  • the tab 17 may be sized so that it is folded as a closure tab against the bag front wall 12 and connected thereto.
  • the lug 17 is designed as a winding lug which, in the closed position, encloses the bag front wall 12 and is detachably fixed to the bag rear wall 13 by means of an edge-side connecting means ( Fig. 3 ).
  • connecting pieces are provided, which are on the one hand on the (inside of) the tab 17 and on the other hand attached to the bag wall 12 or 13.
  • the connecting pieces are designed so that they enter into a releasable connection due to pressing against each other.
  • the connecting pieces are formed as Velcro pieces 18, 19.
  • the Velcro pieces 18, 19, preferably in a matching embodiment, have on the mutually facing sides of a strip-shaped carrier 21 each have a hook and loop coating 20.

Above and below movable dancer rollers 31, 32 are arranged, which perform (in the horizontal plane) a compensating movement and a constant tension in the Velcro strips 25, 26 obtained. Lower stationary (second) guide rollers 33 guide the hook and loop fasteners 25, 26 in a converging downward direction to a connecting member. This has pressure rollers 34, 35 on both sides of the Velcro strips 25, 26. The rollers are driven according to the direction of movement of the Velcro strips 25, 26 (arrows).
