  • the invention also relates to a method for applying elastic elements to a continuous material web, comprising advancing the said elastic elements in series one after the other at a first predetermined speed and advancing the said material web at a second predetermined speed.

The elastic element will then create a suitable elasticity in the finished article.
  • An application of elastic elements can be realised intermittently, i.e. in such a way that individual elastic elements are applied in series one after the other to predetermined positions along the underlying material web.

  • the mating roll 4 rotates at a first, predetermined speed vi along its periphery.
  • the cutting roll 3 has the same speed Vi as the mating roll 4, so that the cutting roll 3 cuts the elastic strip 1 at substantially the same point along the periphery of the mating roll 4 during its rotation.

  • the said elastic elements and the material web 7 can thereby be squeezed together, as a result of the laminating roll 6 forming an abutment surface where the respective elastic element and the material web 7 meet.

  • This feed is realised in such a way that the material web 7 is fed at a speed v 2 which exceeds the speed vi of the second gripping roll 5'.
  • the respective elastic element will be applied to the material web in its elongated state.
  • FIG. 5 illustrates on an enlarged scale how an elastic element 1a is applied to a material web 7 according to the embodiment apparent from Figure 4.
  • the distance d between the gripping roll 5' and the abutment surface 9a defined by the ultrasonic horn 9 is less than the total thickness of the elastic element 1a and the material web 7 in their unworked state.

  • the elongation of the respective elastic element is realised in two separate steps.
  • the mating roll 4 (see, for example, Figure 1) is driven at a peripheral speed v 3 which is lower than the speed v-i of the gripping roll 5, so that an initial stretching of the respective elastic element is realised even before it has been advanced to the material web 7.

This then means that the underlying material web 7 is arranged adjoining the mating roll instead of the gripping roll.
