Definitions

  • the invention relates to a cushion of paper, and to a method and an apparatus for producing it.
  • the object of the present invention is to create a paper cushion which has improved cushioning properties and is less expensive. Improved cushioning properties means that the product has higher resiliency and/or elasticity, or in other words provides better cushioning of items packed, in proportion to the quantity of paper used. A cushioning product is less expensive if less paper is required to fill a given volume, for example on the basis of the way in which the cushioning product is shaped.
  • One such product is characterized according to the invention in that the cushion is a crumpled paper tube.
  • a paper tube in the opened-out state, is upset and thereby crumpled. In comparison with previous products, more air is “trapped” inside this crumpled tube.
  • the circular cross-section disposition of the paper leads to improved properties in cushioning and padding packed items.
  • the cushioning properties are furthermore improved if the paper tube is provided in the longitudinal direction with a strip of paper or adhesive. This is expediently effected by providing that this strip and/or this adhesive is formed when a paper tube is produced from a paper web by folding or rolling in the edges and joining them together.
  • a paper tube that is, to prepare it, specifically by providing that one or more paper webs are joined together along their edges, for instance by directly adhesively bonding overlapping regions or by gluing strips on.
  • These paper tube webs are then processed further to form the cushions or cushion portions in the apparatuses suitable for that purpose.
  • a paper tube web prepared and put together in this way can as a result be made smaller, or in other words narrower, by providing that along the two outer sides of the paper tube, in the flatly put-together state, indented folds are provided.
  • indented folds are provided.
  • the paper tube web is preferably provided with intended tearing points at prepared, standardized intervals. These are points which tear when tension is exerted, as a consequence of the weakening of the material brought about by them. In other words, if tension is exerted on the paper tube web, it tears at the points where it is “supposed to” tear as intended. These points are preferably formed by a perforation and/or by certain notches or recesses.
  • the method for producing the cushion and the apparatus suitable for it are embodied such that the paper tube is slipped onto a core, which distributed over its circumference has rollers (inner rollers) that cooperate with rollers disposed outside the core (outer rollers), at least some of which are driven, and that thus draw in the paper tube, pass it between them, and crumple it.
  • This is preferably accomplished by providing that two groups of rollers, spaced apart from one another in the longitudinal direction, are provided, which are driven at different circumferential speeds, so that between the two groups of rollers, crumpling by way of creasing of the paper material comprising the paper tube web occurs, and this creasing is crumpled further upon the passage through the second group of rollers.
  • rollers are provided, which are disposed on a smaller boundary circle, so that the already-crumpled paper tube is also pushed together in the radial direction and crumpled anew on passing through the last-named rollers.
  • An apparatus for producing a cushion of paper comprises the provision of feeder means for the paper tube web that slip it onto a core and the provision of crumpling means, which crumple the paper tube web that has been opened out by being slipped onto the core.
  • the feeder means are formed by rollers disposed in a first plane transverse to the feeding direction, which are provided both on the core (“inner rollers”) and outside the core (“outer rollers”) in the apparatus; all of these rollers initially continuously open out the paper tube once it has been inserted and then slip it onto the core.
  • further groups of rollers can be provided. They then, as already described, accomplish the crumpling in that first a circumferential creasing occurs by virtue of longitudinal compression, and then a radial compacting occurs by virtue of radial compression ensues.

  • the cushion portion 1 is created by crumpling a prefabricated (configured) paper tube 2 , specifically in the form of upsetting in the longitudinal direction (axial direction) with ensuing compression.
  • One such paper tube 2 is shown in perspective in slightly opened form in FIG. 2, in terms of the cross section of FIG. 3( a ).
  • the term used is also a configured paper web, or a paper tube web 8 .
  • the paper is preferably so-called “kraft paper”, that is, very firm, brown packing paper made of unbleached sulfate cellulose, usually using very long fibers, which is therefore especially tear-resistant. It is understood that this statement should again be understood only as an example.
  • the webs are glued together, as already mentioned.
  • the adhesive layers 7 that are striplike in the longitudinal direction of the cushion portion form, optionally together with the strip 5 , an additional reinforcement of the cushion, which enhances the cushioning properties.

  • a roll 11 is seated on a shaft 10 .
  • the roll is formed by a configured, wound-up paper tube web 8 .

  • One pair of rollers 16 can be seen; a further pair is located perpendicularly before and behind the plane of FIG. 4, in the same vertical plane.
  • the rollers 16 are followed by rollers 17 , which are driven at a somewhat lower speed, so that between the two creasing 8 ′ ensues from upsetting, and upon passage through the paper tube web 8 between the rollers 17 and the core, this creasing undergoes crumpling.
  • Two further rollers 17 are disposed in the same vertical plane, in FIG. 4 in front of and behind the core 15 , with their axes perpendicular to those of the rollers 17 shown. Pairs of rollers 20 , 21 , 22 , 23 , 24 that freely travel jointly are disposed on the core 15 and serve to provide for low-friction travel along the paper tube on the outside of the core. As shown in FIG. 4 a , the rollers 16 plunge by an amount h (plunging depth) between the rollers 20 , 21 , so that they secure the core 15 , in a defined position, against axial displacement.
  • FIG. 5 One possibility for cutting off individual cushion portions from the continuously manufactured band is seen in FIG. 5.
  • a paper tube web 8 is shown in plan view that has perforation lines 12 , or tearing points or lines of separation, at intervals of 80 cm, for instance.
  • perforation lines 12 or tearing points or lines of separation, at intervals of 80 cm, for instance.
  • rhomboid cutouts 13 are provided. If the rollers 16 are now stopped at predetermined time intervals, which correspond to the processing of a particular longitudinal portion, and the rollers 17 are allowed to continue to rotate, then along the perforated line that is then located between the rollers 16 and 17 , one cushion portion 1 is torn off.
  • the tearing off can also be done by other means in the transport direction T, before or after the apparatus shown. Separating the cushion portions can naturally also be done by a cutting device or other separating devices as well.
  • FIG. 6 One simple design of a stand with a paper processing unit 35 for producing such a cushion portion is shown in FIG. 6.
  • the stand for the various components comprises a bottom plate and scaffold 31 , which has rolls 32 and 33 onto which configured paper tube webs 8 are wound.

Transversely to this, but with axes in the same vertical plane and also facing one another in pairs, further pairs of rollers 61 , 61 ′, 62 , 62 ′, 63 , 63 ′, 64 , 64 ′ are provided (see also FIG. 11).
