Definitions

  • the invention relates to a slipcase for a photo book and to a method and a device for producing the slipcase.
  • the invention also relates to folding devices and gluing devices, which can be part of the device for producing the slipcase.
  • Photo books are very individual. As a rule, every photo book is unique, although different photo books can have different numbers of pages. The type of paper and therefore the paper thickness can also vary from photo book to photo book. Accordingly, the slipcases for the photo books should also be different. In particular, the thickness of the respective slipcase should correspond to the thickness of the respective photo book. Producing these individual slipcases in large quantities is relatively complex.
  • a slipcase for a photo book the slipcase being rectangular, the slipcase having an access opening for inserting and removing the photo book and five pages, the five pages having a front, a back, a slipcase back and two connecting pages, which connect the front, the back and the slipcase back together, the slipcase being made from at least two sheets folded and glued together, a first sheet forming the front and a second sheet forming the back.
  • Producing the slipcase by folding and gluing two sheets together, with a first sheet forming the front of the slipcase and a second sheet forming the back of the slipcase, can be relatively easily adapted to the respective photo book, in particular to the thickness of the respective photo book.
  • This therefore enables the production of individualized slipcases, which are adapted to a respective individual photo book, in large quantities with relatively little effort.
  • it enables the production of the slipcases to be easily adapted to the thickness of the respective photo book in such a way that they are a precise fit for the respective photo book, so that they do not lie loosely in the slipcase and can still be easily removed.
  • At least one of the pages has one or more photos of the photo book on its outer surface.
  • at least two of the pages, in particular all pages have one or more photos of the photo book on their outer surfaces.
  • the sides of the slipcase i.e. the front, the back, the back of the slipcase and the two connecting sides, could also be viewed as closed sides, in contrast to the open access opening.
  • the front includes a head end and a foot end, with the access opening being on the left side when the slipcase is held so that the front of the slipcase is viewed with the head end up.
  • the at least one photo on the outer surface of the slipcase is also shown on the outer surface of the photo book.
  • the photo book comprises a front, a back and a photo book spine, the slipcase is designed so that the front sides of the photo book and the slipcase show the same thing and / or the back sides of the photo book and the slipcase show the same thing and / or the photo book spine and the slipcase spine show the same thing.
  • first sheet and the second sheet each have side flaps which are each glued together by means of a first adhesive arrangement, the side flaps glued together forming the back of the slipcase and the connecting sides of the slipcase.
  • Gluing the two folded sheets together by gluing the side flaps also makes it possible to produce individualized slipcases that are adapted to the respective photo book in large quantities with relatively little effort.
  • one of the two side tabs, which together form a respective connection side completely forms the inner surface of the respective connection side, with the other of the two side flaps preferably completely forming the outer surface of the respective connection side.
  • one of the two side flaps, which together form the slipcase spine preferably completely forms the inner surface of the slipcase spine, with the other of the two side flaps preferably completely forming the outer surface of the slipcase spine. If the respective inner surface is formed entirely, i.e. solely, by a side flap, the respective inner surface does not include a step or the like, but is flat or smooth. This further increases the quality of the slipcase as the likelihood of the slipcase damaging the photo book can be reduced.
  • the respective first adhesive arrangement is an adhesive line.
  • the side flaps are therefore preferably not glued using individual adhesive dots.
  • the use of adhesive lines allows for longer-lasting bonding, so the resulting slipcase is very durable. In particular, the slipcase is also very stable with regard to temperature fluctuations. Applying an adhesive line is also easier to control than, for example, applying individual adhesive dots. Applying the adhesive line can also be viewed as a bead application.
  • the respective first adhesive arrangement is a non-curved straight arrangement or a U-shaped arrangement of an adhesive.
  • the respective first adhesive arrangement is a non-curved arrangement, and if the side tabs have a height that is greater than the predefined threshold, the respective first adhesive arrangement is a U-shaped arrangement. If the side tabs have a height less than the predefined one Threshold value, the probability that adhesive will be forced out of the area between the side tabs increases if the adhesive arrangement is U-shaped. On the other hand, this probability is reduced if the height of the side flap is greater than the predefined threshold value.
  • a U-shaped adhesive arrangement is preferably selected for correspondingly higher side flaps.
  • the predefined threshold value is preferably in a range of 10 to 30 mm, more preferably in a range between 20 and 25 mm, and in a further preferred embodiment the threshold value is 22 mm.

It is preferred that the width of the first adhesive assembly between the beginning and the end is in a range of 5 mm to 7 mm. In addition, it is preferred that the distance between a) an outer edge of the respective side flap, i.e. to one or all edges that do not adjoin a first section of the sheet, which forms the front or the back, and b) the respective first Adhesive arrangement is less than or equal to 2 mm and is more preferably in a range of 1 mm to 2 mm. It has been shown that these parameters lead to long-lasting bonds, while at the same time no adhesive is forced out of the area between the side flaps. The bonding is therefore not only very durable, but also very clean.
  • first sheet and the second sheet are different, i.e. not identical.
  • the side tabs of one of the sheets have a greater height than the side tabs of the other of the sheets.
  • the height of the side flap of the first sheet forming the front is greater than the height of the second sheet forming the back.
  • a) the front by folding two contiguous sections of the first sheet and gluing these sections to a second Adhesive arrangement has been formed, with a resulting folded fold edge between the two sections forming a front edge of the access opening, and / or b) the back has been formed by folding together two contiguous sections of the second sheet and gluing these sections with a third adhesive arrangement, wherein a resulting folded fold edge forms a rear edge of the access opening.
