Definitions

  • a method for producing a double-walled cup is to be improved.
  • the flat segment that is to form the outer sheath must be set before the actual winding process on the inner cup and thus fixed until the completion of the winding process.
  • This is usually done by a clamping lever which presses the segment on the inner cup.
  • the counterforce is absorbed by a mandrel on which the inner cup is pushed.
  • the force necessary for a secure fixing of the segment is necessarily so great that the pre-applied adhesive between inner cup and segment is pushed out of the pressing area.
  • the required air gap between the inner cup and outer shell in the region of the clamping lever is reduced to an intolerable level for the isolation of the cup.
  • the finished cup is then limited in its function, possibly even unusable.
  • At least one spacer is mounted on an inner side of the planar segment and / or on an outer side of the sleeve of the inner cup prior to placing the flat segment on the inner cup.
  • the spacer is designed so that it is plastically no longer or only slightly deformable. The spacer thus serves to obtain the dimensions of the insulating gap even with a force of the clamping lever on the segment.
  • the segment can then be wound to the outer shell and it can be ensured that a substantially constant distance between the outer shell and the sleeve of the inner cup is achieved in the finished cup.
  • the double-walled cup produced thereby has very good insulating properties.
  • paper, cardboard or paperboard As a paper material or paper-like material, for example, paper, cardboard or paperboard is considered.
  • paper, cardboard or cardboard can be present in flat segments and these flat segments can then be wound on the one hand to form a sleeve with a circumferential wall and also be deformed to form a cup-shaped bottom element, for example.
  • the sleeve and the bottom are then connected to an inner cup.
  • the outer jacket is also made from a flat segment.
  • the paper material is coated liquid-tight.
  • the inside of the inner cup should be coated liquid-tight.
  • On the outside of the inner cup and on the outer shell can be dispensed with a liquid-tight coating, also to facilitate printing of the outer shell.
  • plastic material which is present in a planar manner is also considered, for example, if it is processed in the same way or at least as similar as paper material to a cup or a lid.
  • Flat plastic materials are, for example, also plastic laminates.
  • the sheet-like plastic material, which is in segmental form is also wound around a center mandrel and connected in the region of the overlap to form a, in particular conical sleeve.
  • a pot-shaped bottom or a cup-shaped cover element can be formed from the sheet-like plastic material by a circular blank is folded in its edge region opposite its bottom surface approximately vertically upwards.
  • paper-like plastic material to be processed can not be greatly deformed, for example, kinked, without losing its insulating properties and sealing properties.
  • the present invention can be used for paper-like plastic materials to be processed, but it is not specifically designed for paper-like plastic materials to be processed but can of course be used with considerable advantages for paper material.
  • the spacer is mounted at least in the middle between the two side edges of the planar segment.
  • the spacer can provide an abutment in fixing the planar segment to the inner cup and the segment can be wound with little effort to the outer shell.
  • the spacer extends to the finished cup in the direction of the bottom of the cup to an opening of the cup.
  • the spacer can in particular be easily mounted on the segment, without hindering a bending of the segment during winding of the outer shell.
  • the spacer can also be distributed over the segment and yet do not hinder the bending of the segment during the winding of the outer shell.
  • the attachment of the spacer on the application and solidification of at least one adhesive trace, in particular hot melt adhesive, on, wherein the spacer is formed by the solidified adhesive trace is formed by the solidified adhesive trace.
  • nozzles are required for applying adhesive anyway.
  • one or more traces of adhesive are applied to the outside of the inner cup, for example by means of a nozzle, alternatively or additionally, at least one adhesive trace is applied to the inside of the planar segment. After solidification of this adhesive track then serves as a spacer and the flat segment can be placed on the inner cup and fixed by means of a clamping lever. Subsequently, the outer shell can then be wound from the flat segment.
  • Paper pulp is called pulp.
  • a spacer By means of a track made of paper pulp, which solidifies after application, a spacer can be realized comparatively inexpensively.
  • a great advantage is that the track of paper pulp in a continuous process, for example by means of a nozzle, can be applied.
  • a foam track can be realized in a continuous process in a simple and cost-effective manner, a spacer.
  • a foam can be used, which cures automatically after application.
  • the spacer has a height of at least 0.2 mm and at most 5 mm, preferably between 1 mm and 3 mm.
  • the spacer is applied to an inner side of the planar segment and before placing the flat segment on the inner cup an outer side of the inner cup is provided with at least one adhesive trace for fixing the outer shell on the inner cup.
  • the segment is provided with one or more spacers and the outside of the inner cup with at least one trace of adhesive. Both the spacer and the adhesive track can thereby be applied unaffected from each other.
  • the adhesive trace is indeed where it is touched by the spacer, compressed, but due to the spacer or more spacers during the winding of the outer shell but then still obtain a distance between the outer shell and the inner cup.
  • a plurality of strip-shaped spacers are applied distributed over the inner surface of the planar segment and / or over the outer surface of the inner cup.

  • the application of a plurality of rectilinear, strip-shaped spacers on the inside of the planar segment can take place in a particularly simple manner, namely, during a linear transport movement of the planar segment, the spacers are applied by means of nozzles.
  • these strip-shaped spacers then run exactly in the height direction only in the case of a cylindrical cup, and in the case of a conical cup, the spacers then run obliquely to the height direction.
  • they can be arranged with increasing or decreasing distance from each other on the inside of the planar segment.
  • At least one device in particular a nozzle, is provided for attaching the at least one spacer.
  • a spacer By means of a nozzle, a spacer can be applied in a particularly simple manner, for example by applying an adhesive trace, a track of paper pulp or a foam trace.
  • transport means are provided for moving the planar segment along a section-wise rectilinear or circular path, wherein the at least one device for attaching the spacer is arranged on a rectilinear or circular section of the path.
