  • precautions must be taken to ensure the continuity of the web travel process even during the effects of the pretensioning force in particular, but also the impact impulse. This can be implemented, for example, by cyclically carrying along and returning the device 1 or by means of a web store after the supply roll 40 and before the device 1 .

  • This can advantageously be used as sleeve packaging, with the film tube 14 being pushed over a package. It is particularly advantageous if the tubular film 14 consists of a shrink film which shrinks when heated and lies tightly and smoothly as a shrink sleeve against the wrapped packaging.
  • the weld seam 12 does not affect the areas of the shrink film surrounding it by heating. While in known welding processes the flow of heat from the (also comparatively wide) weld seam into the surrounding plastic film leads to unattractive, undesirable deformations that are still visible even after shrinking, especially wrinkling, and thus produces an aesthetically unsatisfactory result, the invention can avoid these disadvantages.
  • the weld seam 12 is very narrow and, as explained above, avoids thermal damage to the plastic film 10 adjoining the weld seam 12, which also remains smooth in the area of the weld seam 12 and moreover retains its full shrinkage capacity.
  • a shrink film can also be used in this application, in particular in order to wrap a box, the wrapping lying tightly against the box after shrinking.
  • a shrink film can also be used in this application, in particular in order to wrap a box, the wrapping lying tightly against the box after shrinking.
  • Fig. 12 shows a schematic side view of an embodiment of a device 1 according to the invention in a joining-separating combination, i.e. immediately after the welding or practically at the same time, the plastic films 10 are separated directly in the middle of the already very narrow weld seam 12 he follows. This becomes particularly clear in the enlarged representation in FIG.
  • the device 1 includes the welding jaws 2, 4, shown after the return stroke, which releases the joining and separating point.
  • FIG. 13 schematically shows an enlarged view of a joining/separating combination with joined plastic films 10 and a separated area where the part protruding beyond the weld seam 12 is separated within the weld seam 12 .
  • the very narrow weld seam 12 can be seen here.
  • the material adjacent to the weld 12 is not thickened, which already shows that excess material of the plastic films 10 is not melted and displaced as is the case with other prior art heat sealing processes. It is also evident that the heat-affected area 13, whose boundary to the unaffected plastic film 10 is represented by a dashed line, is limited to the weld seam 12, the joining zone, and leaves the surrounding areas of the plastic film 10 unaffected. 14 schematically shows an enlarged view of a joint with joined plastic films 10 without separation at the weld seam 12, so that the plastic films 10 extend on both sides of the weld seam 12. The very low weld seam 12 with the height H at the joining zone, the fused plastic films 10, can also be seen here.
  • the material next to the weld 12 is also not thickened, which shows that no excess material of the plastic films 10 is melted and displaced. Rather, the heat-affected area 13 is narrowly limited to the area of the weld seam 12 and neither the plastic films 10 nor an area outside the plastic films 10, for example heat-sensitive packaged goods within a package, are adversely affected by undesired heating.

Abstract

L'invention concerne un cordon de soudure, un procédé et un dispositif pour relier des films en plastique (10) par assemblage thermique, les films en plastique (10) étant reliés le long d'un cordon de soudure (12) entre des éléments de soudage (2, 4). Selon l'invention, le dispositif comprend une paire d'éléments de soudage (2, 4) non chauffés, entre lesquels les films en plastique (10) sont disposés parallèlement les uns aux autres à des fins d'assemblage thermique. Un appareil de génération d'impulsions (30) introduit une impulsion d'impact d'une première intensité (Fi 1) à l'aide de l'un des éléments de soudage (2, 4), une durée de pénétration dans les films en plastique (10) étant inférieure à 10 ms. L'impulsion d'impact agit sur les films en plastique (10), un chauffage induit par la déformation étant généré dans le matériau et le cordon de soudure (12) étant formé dans une région d'action des éléments de soudage (2, 4). L'invention concerne également l'utilisation d'une presse de forgeage par soufflage.
