"Binding for loose sheet material"

The invention relates to a binding for loose sheet material, consisting from a front and a rear outer cover, which are connected to one another via a binding spine.

Such a cover is known and is used to bind loose sheets of paper by gluing the spine into brochures;: u. However, the stronger outer covers can easily tear out here, because the bending forces are transferred to the glue backing when opening and closing it.

Furthermore, bindings for loose sheet material in the form of folder are also known, in which either the loose sheet material is filed on a strip, which is created by double folding the spine inwards (e.g. GM 77 02 137 unä- " DE-PS 15 36 657) or the sheet material between a pinch fold of the total folded inward between the outer cover The back is filed (DE-OS 23 32 4 64). In these folders, however, there is a glue-back binding of the sheet material not possible.

The invention is based on the object of creating a cover of the generic type specified in the introduction, which is both suitable for glue back binding as well as for all common staple and small-rail binding.

The brochure bound with glue spine (Fig. 1) consists of a rear outer cover 1, the sheet material 2, a front one Outer cover 5 and a back cover 3. Prefabricated covers with particularly thick rear outer covers 1 can be used for easier processing - be stapled to the front outer cover by means of clips 7 züsaiiimengeheftet.

For the production of the glue back 4, the outer cover 5 is first arranged flat in the extended position of its fold 6. Thus, the edges 8 of the sheet material 2 and the free, inner longitudinal edges 9 of the rear outer cover 1 of the bindings are stacked at a common abutting edge 10, on the surface of which the glue backing 4 is applied. After hardening the glue and the separation of the brochures is the respective front outer cover 5 on the folding grooves 11, 12 and 6 edged and folded from the bottom to the front. For smaller or larger stack heights of the sheet material 2, more can Folding grooves 13 and 14 may be provided.

In the case of the cover with clamping rail 15 shown in FIG the stacking height of the sheet material 22 is limited by the height of the back of the clamping rail 15. Hence the burden of the cover is limited by the weight of the booklet. Therefore, thinner binding materials can be used to advantage the outer covers 21, 25 and the binding back 23 are made from one piece. The front is also located here Outer cover 25 in the extended position of the fold 26 before the clamping rail 15 is pushed on. ' As a result, the sheet material 22 is lighter to align with the abutting edge-210 and the clamping rail postpone. Then the front outer cover is folded forward into the position of use.
