Abstract
The object of the invention is a method for shrinking a shrink film (1). The method is characterized in that energy is generated in the shrink film (1) by supplying a resistive area in the shrink film with electric power; an area in the shrink film absorbing microwaves with microwaves; or similar impulses having a direct impact on the shrink film.
Description
A method for shrinking a shink film
This invention relates to a method for shii king a shrink film.
Nowadays shrink films are shrunk by using hot-air blowers, by radiating heat, or by heating in furnaces. However, all these prior-art methods have the drawback of involving very high energy consumption. Also, the time required for the shrink film to shrink as desired depends on the heat, i.e. the energy. Slirinking usually takes several seconds. In view of this, the object of the invention is to eliminate the draw- backs mentioned above. The method of the invention is characterized in that energy is generated in the shrink film by supplying a resistive area in the shrink film with electric power; an area in the slirink film absorbing microwaves with microwaves; or other similar impulses having a direct impact on the shrink film. Tests have indicated that shrink film which has been made resistive is shrunk in 200 ms with a 12V voltage and 1 A current, into a state that would require several seconds in a furnace, which besides, has 20-fold power consumption compared to the invention. The invention generates energy directly on the right spot, without causing any waste heat, in contrast to all prior-art methods.
One embodiment of the invention is characterized in that the shrink film is made resistive by admixing a resistive substance in the film proper, so that the shrink film itself becomes either totally or partly resistive. With this proceeding, the shrink film will shrink either in specific areas ar all over, exactly as desired.
Other embodiments of the invention are described in the dependent claims.
The invention will be described below with reference to the accompanying drawings, in which
Figure 1 shows a shilnk film which is resistive in itself, Figure 2 shows a slirink film provided with surface resistances,
Figure 3 shows a shrink film provided with a resistance coating produced for instance by offset printing,
Figure 4 shows the shrink film when opened,
Figure 5 shows the shrink film bent into a cylindrical shape, Figure 6 shows the shrink film fitted around a pile of coins and
Figures 7 and 8 show various shrink film embodiments.
The shrink film in figure 1 has been produced by admixing a resistive substance in the plastic material 1, the resistive substance being heated under the effect of elec¬ tric power, and by slrrinking the shrink film uniformly. In figure 2, surface resistan¬ ces 2 have been attached to the surface of the film 1. In figure 3 resistive prints 3 have been made on the surface of the shrink film by using the offset method. The shrink film may optionally be multilayered, and in that case one of the layers is resistive. The resistive area is supplied with low- voltage current, for instance 12 to 14V. The figure illustrates direct voltage, however, alternating voltage is equally possible. The shrink film 1 is provided with contact surfaces 4, 5, to which current is conducted and from where it passes on to the resistive area. Figure 7 shows the resistive area 6 focussed in the centre of the shrink film. This particular spot will be heated at a considerable higher rate and will shrink to a larger extent than the remai¬ ning area. At the edge of the shrink film a glue surface 7 is provided, which joins the edges of the shrink film, around a pile of coins for instance, as illustrated in figure 6. In shrinking, the ends of the shrink film bend to overlap, as indicated by arrows 8.
The design of the device is not shown in detail here, because it consists of simple components known per e, and furthermore, it is appreciably cheaper than the furnace option cited by way of example.
