Definitions

  • the invention relates to a folding device or the like which layer material, sheet layers, similar or others Blanks can be folded so that two or more folding legs from an approximately level starting point in a different relative position can be transferred, e.g. into a right-angled, parallel plane or any intermediate position in between.
  • the two folding legs are in one piece over a fold or fold zone e.g. in the manner of a linear film or folding joint with one another connected.
  • the sheet layer is not yet separated for folding Connection with a continuous path in a horizontal or other funding level and one at the respective Edge area lying on the long side engages with one the guiding surface or tread, which rises to the conveying level, so that this edge area the one folding leg or one forms strip or tab-shaped folding part during the part of the material remaining in the conveying plane the other Folded leg forms.
  • the folding part can do less or more can be folded as 90 ° or arbitrarily up to approximately 180 °, so that he then takes cover with the other folding leg and the folding zone is parallel to the conveying direction.
  • the folding part slides under system pressure on one or several guiding surfaces designed as folding curves.
  • the folding zone with a cross-sectional weakening beforehand e.g. with an embossing, a waste-free slot or perforation or the like, through which the bending stiffness of the material in the area of the folding zone the subsequent areas of the folding legs weakened becomes.
  • a cross-sectional weakening beforehand e.g. with an embossing, a waste-free slot or perforation or the like, through which the bending stiffness of the material in the area of the folding zone the subsequent areas of the folding legs weakened becomes.
  • This can e.g. with a Z-shaped fold two parallel fold folds to be folded in opposite directions are kept at a precise distance from each other. Indeed arises for the production of the cross-sectional weakenings increased effort in tools and machining space.
  • the Folding can also take place along a run or Guide slot take place by continuous decrease its slot width in the conveying direction and by double the angled cross-sectional shape the edge strip inevitably into a double angled Form transferred.
  • the edge strip is however only at the end of the guide slot on both sides of the surface guided while he was in the conveying direction in front of each only point or line at the boundary of the guide opening is led. This results in high throughput speeds Instabilities of the marginal or folding leg and the layer material, which leads to inaccuracies of Folding or damage to the sheet material can.
  • the invention has for its object a folding device to create the disadvantages of known training or of the type described are avoided and with which in particular at high conveying speeds then exact foldings can be done if the associated folding zones not due to cross-sectional weakening are predetermined or pre-processed.
