  • the inner cup 102 and the outer shell 101 formed from a blank or a development are formed from mutually different materials.
  • Such cups 100 further have an open and a closed end region, wherein usually a cross-sectional dimension in the open end region is greater than that in the closed end region.
  • the open end region also usually has a flange-shaped edge strip, which can be connected to a closure device, in particular sealed.
  • arbitrary cross-sectional shapes can be used, which may also be designed differently from one another.
  • this cup 100 there are several methods to make this cup 100.
  • One possibility is to wrap the outer shell 101 around the finished inner cup 102.
  • the inner cup 102 is usually received by a mandrel, which takes over the support and support during the winding process.
  • Another possibility is to produce inner cup 102 and outer shell 101 independently of each other and then push them into each other.
  • the inner cup 102 has for this purpose in the bottom region usually a bead on the sliding down of the outer shell 101 of the conical or tapered tapered inner cup 102 prevents if it is not or only slightly glued to the inner cup 102.

  • first outflow opening and / or the channel is oriented in such a way that it has or have an outflow direction directed toward the side facing away from the center of the first holding device carrier, because this not only allows the dissolving process of the unwinding to be carried out by the holding device carrier at the same time so that the transfer movement can take place.

This can be done during the further rotation of the holding device carrier up to the planned transfer a compression of the adhesive seam.

  • the preparation station comprises cooperating pairs of conveyor belts and the pairs are arranged in the conveying direction transversely to the conveying direction distanced from each other and thereby spanning a conveyor plane. This results in a clear clamping of the still planar windings to be transported. Thus, the staggered and isolated transactions are conveyed safely and precisely to the individual workstations. It is also expedient if the preparation station at the end of the conveyor belt facing the first holding device carrier comprises a feed carriage with means for holding the unwinding to form the outer casing and the feed carriage from a position taking over the unwinding from the conveyor belts into the position providing the unwinding towards the first holding device of the first holding device carrier is adjustable.

  • the machine has an adhesive application nozzle, which is kept clean in a rest position by a moistened, rotating sponge. Over time adhesive deposits may occur on an adhesive nozzle that may interfere with its proper functioning or even cause it to malfunction. For this reason, it is in principle advantageous to clean the nozzle between the adhesive jobs. It is particularly advantageous if this is done with a rotating, moistened sponge, which - as experiments have shown - particularly good for this task is suitable. In particular, when cold or hot glue is applied, the nozzle can always be kept clean in this way.
