Device for easily detachable fastening of paper or Polienbbogen »

The hole-free fastening of paper or foil sheets on hot boards or reproduction walls are associated with a number of inconveniences and inconveniences, either in drawing or in tensioning and disrupt detachment »

The easiest and most convenient stapling device is still the thumbtack, its use, however, both plastic documents and valuable Prohibit originals »For this purpose, there is more and more gluing, both with one-sided and double-sided. which have to be handled carefully and often disturb due to residues.

Magnetic devices are well suited for reproduction purposes, although they are expensive, they are either not suitable for drawing machines or require a very cumbersome system _{or the like}

The electrostatic charging of plastics is an ideal stapling agent for light to medium-weight papers and foils, but it is usually not permanent, especially when the air humidity is high, so that e.g. initially well-adhering Zenfio bi '^ c. \ ^ FIe * who Gently loosen from the board and fall off.

According to the invention a device for attaching the characters or Reproduction master sheets used, the three different types, on known adhesive effects are combined more or less as required and thus the degree of fastening required for the respective purpose with the least possible effort achieved.

As an exemplary embodiment, approx. 30 mm wide, 0.5 am thick, electrostatically chargeable, transparent strips made of PVC (Astralon) which in their longitudinal direction half with a width of about 15Hm Double-sided self-adhesive tape are provided to frame these strips the arch to be attached. The procedure here is that two Stapling strips are arranged at right angles, so that the sheet is in the Strip angles can be pushed in after lifting the free edges can »For larger formats, the other two Curved edges still fixed with the same plastic strips, while for smaller arches it is often sufficient to attach two edges »

The adhesive effect of the stapling strip grows the further you go along the edge of the sheet pushes under the adhesive strip to its self-adhesive strip. When using suitable, not too hard adhesive strips, the Gluing of the sheet edge to the self-adhesive striped cat fairy clearly noticeable.

Hur when there is a lot of pushing back and forth on the bow for drawing work with a drawing machine or drawing equipment

it may be useful to cut the upper edge of the Bogena from a narrow one To stick over strips of the self-adhesive edge of the staple strip. Although the filing strip then holds the sheet immovably, it is very easy and convenient to remove compared to normal self-adhesive strips because of its considerably greater material thickness. The filing strips can be used repeatedly and often before your / Self-adhesive strips must be replaced.

The filing strips are particularly effective with plastic documents, e.g. made of PTC or polystyrene, which can be very easily rubbed with Cloths made of polyamide fibers are electrostatically charged. The discharge of the electrostatic charge can be prevented by placing a metal foil that is as earthed as possible under the plastic foil or plate or plate is attached.

Reproduction walls equipped with this adhesive device allow A quick change of the originals, especially since they only need to be pushed under the filing strips if they show a tendency to roll or are so heavy "that they do not adhere electrostatically"

A drawing sheet framed with these filing strips is absolutely safe against tearing or edge damage, because neither the drawing machine nor the drawing square can drive under the drawing sheet.
