Uppfinnare: J. Burgmer. Inventor: J. Burgmer.

Foreliggande uppfinning avser ett kopieringsblock, d. v. s. en bunt blanketter eller anteckningsblad av godtycklig art och form, vilka tillsammans med mellan dem anbragta karbonpapper upptill hro forbundna ph lamp- ligt satt, t. ex. hoplimmade eller sammanhaf- tade till ett block. Vid dylika kopieringsbloek bar anteckningsbladen sedan de utfyllts kun- na om mojligt med ett enda grepp skiljas fran karbonpapperen och fran varandra. For detta Ondamal ha bladen vid sin ovre kant omedelbart under hoplimningen eller sammanhaftningen forsetts med perforering i form av hal eller slitsar. Avskiljandet av bladen sker genom att med ena handen fasthhlla blocket vid den ovre kanten och med andra handen fatta om bladen vid den nedre kanten, vid vilken karbonpapperen ieke n& lika langt ned som anteckningsbladen. Genom ett haftigt ryck eller avriva bladen snett nedat kan anteckningsbladen skiljas fran karbon; papperen. Vid block av joke alltfar stort omfang gar delta for sig utan vidare, men om blocket emellertid innehaller ett stOrre antal blanketter eller anteckningsblad bereder det vissa svarigheter att avskilja bladen. Delta har man sokt avhjalpa genom att perforera bladen ph ett shdant satt, att de kunna latt avskiljas, i det att bladen forsetts med haleller slitsperforering, vid vilken halen och slitsarna aro vasentligt storre an de mellan dem kvarlamnade pappersstyckena. Man her till slut gatt over till att i papperet utstansa hal eller slitsar av mycket stor langd, mellan vilka kvarlamnats helt korta pappersstycken. Darigenom uppstar emellertid olagenheten, att blockets byre kant, d. v. S. den hoplimmade eller sammanhaftade listen, vilken ju alltid blir nagot tyngre, latt kan brytas av utefter en dylik svag perforeringslinje, vilket fOrsvarar blockets inforande i en skrivmaskin. Vidare kunna de genom endast belt korta pappersstycken fasthallna anteckningsbladen latt avslitas innan de utfyllts eller in-forts i en skrivmaskin, varfor anvandande av dylika block varit forenat med atskilliga olagenheter och de ofta i fortid blivit helt obrukbara. The present invention relates to a copying block, i.e. a bundle of forms or note sheets of any kind and shape, which together with carbon paper arranged at the top connected to each other are suitably arranged, e.g. glued or bonded together into a block. In the case of such copying blocks, the notebooks, once filled, could, if possible, be separated from the carbon paper and from each other with a single grip. For this purpose, the blades at their upper edge immediately during gluing or bonding have been continued with perforation in the form of slips or slits. The leaves are separated by holding the block at the upper edge with one hand and grasping the leaves at the lower edge with the other hand, at which the carbon paper does not reach as far down as the note sheets. By a violent jerk or tearing the leaves obliquely downwards, the note sheets can be separated from the carbon; the paper. In the case of blocks of jokes, an excessively large number can participate without further ado, but if the block nevertheless contains a larger number of forms or note sheets, it prepares certain responsibilities to separate the sheets. Delta has been sought to remedy this by perforating the sheets in such a way that they can be easily separated, in that the sheets are continued with halos or slot perforations, in which the tail and the slits are substantially larger than the pieces of paper left between them. In the end, they proceeded to punch out slips or slits of very large length in the paper, between which completely short pieces of paper were left. This creates the illegality, however, that the bare edge of the block, i.e. the glued or bonded strip, which always becomes somewhat heavier, can easily be broken off along such a weak perforation line, which defends the insertion of the block into a typewriter. Furthermore, the notepads held only by short pieces of paper can be easily torn off before being filled in or entered into a typewriter, for which reason the use of such blocks has been associated with numerous inconveniences and they have often become completely unusable in the past.

Dessa nackdelar avhjalpas genom foreliggande uppfinning, enligt vilken anteckningsbladen joke som hittills fOrses med alltigenom likformig utan med olika perforering, i det att de yttre, lattare avrivbara bladen fOrses med starkare perforeringslinje, under det att de inre bladen, som ha battre faste, f8rses med svagare perforeringslinje. Genom denna olika perforering kan blocket latt skiljas isar, eftersom de inre bladen darvid erbjuda mind-re motstand, under det att de yttre bladen, vilka genom sin placering anda Alt kunna avskiljas, tack vare sin starkare perforeringslinje giva blockets kant 5kad stabiliteL sh att saval avbrytning av densamma som ofriviligt lossnande eller sonderrivning av bladen utefter perforeringslinjen undvikes. These disadvantages are remedied by the present invention, according to which the note sheets joke hitherto provided with a completely uniform but with different perforation, in that the outer, more easily tear-off sheets are provided with a stronger perforation line, while the inner sheets, which have better firmness, are provided with weaker perforation line. Due to this different perforation, the block can be easily separated by ice, since the inner leaves thereby offer less resistance, while the outer leaves, which by their location can be separated by Alt, give thanks to their stronger perforation line give the edge of the block 5kad stability. interruption thereof as involuntary loosening or probing of the blades along the perforation line is avoided.

Alit efter blockets omfang kan den olika perforeringen utforas pa manga satt. Sh kunna t. ex. de bagge yttre anteckningsbladen forses med starkare perforeringslinje och de bhgge darunder anbragta med nagot svagare perforeringslinje, under det att de &riga, blockets inre karna bildande bladen ha en mycket svag perforeringslinje i form av slitsar eller dylikt. Perforeringslinjerna kunna ocksa vid mycket omfangsrika block utifran och Mat likformigt goras alit svagare I Or att darefter i blockets andra del ater tilltaga i styrka mot det sista bladet. Genom uppfinningen erhalles ett block, som är tilrackligt motstandskraftigt for att forhindra att den Owe kanten pa nagot satt skadas, men vars bled likval 'Ott kunna isarskiljas. Depending on the size of the block, the different perforation can be performed in many ways. Sh can e.g. the ram outer outer sheets are provided with a stronger perforation line and the lower ones are provided with a slightly weaker perforation line, while the other sheets forming the inner core of the block have a very weak perforation line in the form of slits or the like. The perforation lines can also at very voluminous blocks from the outside and Mat uniformly make alit weaker I Or to then in the second part of the block again increase in strength towards the last blade. The invention provides a block which is sufficiently resistant to prevent the Owe edge from being damaged in any way, but whose blade can still be separated.

Ett exempel pa en utforingsform av uppfinningen askadliggores pa bifogade ritning. An example of an embodiment of the invention is shown in the accompanying drawing.

Harvid aro tolv stycken anteekningsblad till- sammans med elva stycken mellanliggande karbonpapper vid ovre kanten forenade till ett kopieringsblock, sasom framgar av fig. 2. Bladen aro fOr tydlighets skull visade med nagot inbordes mellanrum. Twelve annotation sheets together with eleven intermediate carbon papers at the upper edge are joined to form a copying block, as shown in Fig. 2. For the sake of clarity, the sheets are shown with some inboard spaces.

Fig. 1 visar blocket sett framifran, varvid delar av de framre bladen Oro avrivna. Anteckningsbladet a Or nagot under blockets kant c forsedd med en perforeringslinje med forhallandevis langa pappersstycken mellan de slitsformiga perforeringshalen, Under 2— bladet a är ett karbonpapper e1 anbragt, varefter f8ljer nasta anteckningsblad & med en perforeringslinje d, vars slitsar och mellanliggande pappersstycken Aro nagot kortare, sa. att detsamma kan lattare avrivas An. bladet az. Darefter foljer ett karbonpapper e3 och darpa det tredje anteckningsbladet a med en. annu svagare perforeringslinje d3. Det darunder anbragta karbonpapperet är betecknat med e'. Av ritningen framgar, alt karbonnapperen nedtill aro nAgot kortare an skrivbladen, sa att de senare med sin kant b na framom de form. Perforeringslinjen el' ph nasta anteckningsblad a4 är annu svagare an perforeringslinjen d. Fig. 1 shows the block seen from the front, with parts of the front blades Oro torn off. Note sheet a Or slightly below the edge c of the block provided with a perforation line with relatively long pieces of paper between the slit-shaped perforation holes. , sa. that the same can be more easily torn off An. bladet az. Then follow a carbon paper e3 and dab the third note sheet a with one. annu weaker perforation line d3. The carbon paper placed underneath is denoted by e '. The drawing shows that the carbon button at the bottom is slightly shorter than the writing sheets, so that the latter with their edge b in front of the shape. The perforation line or the next note sheet a4 is even weaker than the perforation line d.

De ovriga bladen fram till blockets mitt kunna vara forsedda med en alit svagare och darigenom lattare avrivbar perforering, vii-ken darefter pa bladen i blockets andra halft ater tilltager i styrka mot det sista bladet. I de fiesta fall torde det emellertid vara tillrackligt for att blocket skall bliva tillrackligt stabilt, samtidigt som bladen latt kunna avrims, om de inre bladen aro f8rsedda med svagare perforeringslinjer och det eller de bagge framsta bladen ha en starkare perforeringslinje. The other blades up to the middle of the block can be provided with a slightly weaker and thereby more easily tear-off perforation, which then on the blades in the other half of the block increases again in strength against the last blade. In most cases, however, it should be sufficient for the block to be sufficiently stable, while allowing the blades to be defrosted, if the inner blades are provided with weaker perforation lines and the foremost blade or blades have a stronger perforation line.

Claims

Patent claim:

Copy pads, consisting of a number of note sheets, which together with the carbon paper sheets arranged between them are connected ph aptly set, e.g. glued together or bonded together into a block, the note sheets in and separating from the carbon paper and from each other at the lower edge slightly in front of the carbon paper and immediately during gluing, bonding, etc. are provided with a perforation line, can be drawn therefrom, In relation to the perforation on the inner note sheets, it is a challenge that the two outer sheets offer greater resistance to tearing.

2. Copying blocks according to patent claim 1, characterized in that the perforation line on the note sheets arranged in the middle of the block is weakest against tearing, while the other note sheets are provided with against the first resp. last blade against tearing alit stronger perforation line.
