Definitions

  • the invention relates to a method for all-round labeling of objects, in particular cylindrical battery bodies, in which labels provided on the underside with a layer of pressure-sensitive adhesive are fed to the objects on a carrier tape on which they releasably adhere, in which the labels in front of the objects by deflecting the carrier tape from the Carrier tape can be released and in which the labels are glued to the objects and the lower edge areas of the labels in an overlap area on opposite upper edge areas of the same labels.
  • a pretreatment of surfaces to be labeled by flame, abrasion, corona treatment or glow discharge is known from DE-24 46 373 C2, a chemical pretreatment from the book by the buyer, Helmut, "Working with plastics", volume 2, processing, Berlin, Heidelberg , New York 1981, Table 8.4.
  • the object of the invention is to provide a method according to the preamble of claim 1, which avoids the lifting of the labels from each other in the overlapping areas in a simple manner.
  • the method is characterized in that the surface energy of the tops of the labels at least in the top edge areas to increase the adhesive strength of the pressure-sensitive adhesive layer on them is increased by at least one corona pretreatment immediately before the deflection.
  • At least one corona discharge wire is preferably arranged above the base plate at a distance from the labels on the carrier tape, transversely to the direction of movement of the carrier tape.
  • the overlap area has a width of 3 to 5 mm, so that a distance between the overlap area and the corona discharge wire of approximately 10 mm is particularly suitable in order to achieve a uniform pretreatment in the edge area mentioned.
  • the corona treatment with a corona discharge wire or each corona discharge wire should be 2 to 5 ms, preferably 3 to 4 ms.
  • the corona discharge wire with an electrical one Power from 100 W to 300 W per 100 mm length, preferably 150 to 200 W per 100 mm length at a voltage of 20 to 35 kV, in particular 25 to 30 kV, with a frequency of 15 to 25 kHz, in particular 18 to 22 kHz to feed.
  • the surface energy should be increased considerably, namely to more than 40 mN per m, in particular more than 45 mN per m.
  • the labels contain a metal layer, in particular a metal layer produced by vapor deposition and plastic layers adjacent to this metal layer, it can happen that the metal layers evaporate during the corona treatment and the plastic layers melt, as a result of which the labels are at least damaged on the edges.
  • the overlap regions are preferably made wider than those edge regions of the labels which can receive edge defects through the pretreatment.
  • a base plate 2 is shown in section, over which a carrier tape 4, on which there are labels 8 provided on the underside with a pressure-sensitive adhesive layer 6, is drawn around a deflection edge 10.
  • the labels 8 with their pressure-sensitive adhesive layer 6 detach from the carrier tape 4 in a known manner in order to be applied to objects to be labeled.
  • a corona discharge device is located above the base plate 2 12 with a shielding housing 14 and two corona discharge wires 16, 18 arranged in the direction of movement of the carrier tape 4.
  • the corona discharge wires 16, 18 are enclosed by quartz glass cylinders 20, 22.
  • the front upper edge regions 24, 26 of the labels in the direction of movement are corona-treated in two steps.
  • the dimensions and dimensions are preferably as stated above. Harmful gases released during the corona treatment are extracted by a suction device 28.
  • the corona treatment can also be carried out in such a way that it is used for other purposes.
  • the labels are still printed after they have been applied to the objects, for example by means of an inkjet printing process.
  • the compressive strength is increased if there are remnants of the corona treatment on the surfaces of the labels.
