Two connecting rods or pivot arms 33, 34 are thus eccentrically mounted on the shaft 7 in ball bearings 35, 36, which are coaxial embedded but not coaxial with the shaft 7 and the ball bearings 8, 9. The upper spirits of the connecting rods are united by means of a shaft 24, which is rotatably mounted in the connecting rods 33, 34, which thus move synchronously with each other, with the aid of ball bearings 37 resp. 38. Attached to the shaft 24 is a slide member 39 which moves up and down in the guide member 14, the vertical sides of which are provided with recesses or grooves 41 (Fig. 3) for the slide member 39, which is most clearly shown in Figs. 4 and 5.

Slidorganet 39 är fOrsett med ett spar 42 och tva skruvhal 43, vilka organ tjana till slidorganets fastsattning pa axeln 24 medelst skruvar 44. Slidorganet 39 är avsett far selektiv stansning i fern markeringspositioner pa en kodrernsa 40 och bestandigt aterkommande stansning i en sjatte markeringsposition, vilka positioner ligga pa en rat linje, som foretradesvis är vinkelrat mot remsans langdriktning, i vilken remsan frammatas genom perforeringsanordningen i enlighet med uppfinningen. Slidorganet 39 är dad& forsett med ett fast, mot den sjatte markeringspositionen svarande paverkningsorgan 46 samt med tre 8ppningar 47 for tre rorliga paverkningsorgan 48a, 48b och med tva. oppningar 49 f6r tva rorliga paverkningsorgan 50a, 50b. Paverk ningsorganen 48 ligga i samma vertikalplan som resp. anslagsskruvar 30, och paverkningsorganen 50 ligga i samma vertikalplan som resp. anslagsskruvar 29. Varje paverkningsorgan 48, 50 utgiires av en svangbar tvaarmad vinkelhavstang, vars ena havarm 48a, 50a är avsedd att komma till anliggning mot en anslagsskruv 30 resp. 29 och vars andra havarm 48b, 50b utgor ett ankare, som är belaget mitt for och samverkar med ett par magnetkarnor 19 resp. 20 till bildande av en magnetisk krets. Atminstone den ankaret bildande havarmen 48b, 50b bestax av magnetiskt material. Samtliga paverkningsorgan 48, 50 aro svangbart lagrade kring en gemensam axel 52, som är fast anbragt i en urborrning 53 i slidorganet 39. Paverkningsorganen 48, som samverka med magnetkarnorna 19, fOrhandspaverkas i riktning bort fran dessa, dvs. moturs i fig. 2, av en fjader 54 med tre fjadertungor, en for varje paverkningsorgan. I analogi harmed forhandspaverkas paverkningsorganen 50, som samverka med magnetkarnorna 20, i riktning bort frail dessa, dvs. medurs i fig. 2, av en fjader 55 med tva fja.dertungor, en f6r vane paverkningsorgan. De bada fjadrama 54, 55 dro medelst skruvar 56 (fig. 3) fasta i skruvhal 57 (fig. 4) i slidorganet 39. Med det fasta paverkningsorganet 46 samverkar en stanspinne 59, och med vart och ett av de svangbarn paverkningsorganen 48, 50 samverkar en stanspinne 60. Stanspinnarna 59, 60 aro inforda genom ett hal 61 (fig. 4) i slidorganet 39 och darefter forflyttade i sidled (parallella med sin langdriktning) i ett spar 62 i slidorganet tills de kommit i linje med var sitt paverkningsorgan 46, 48 och 50 och var sin dubbel styrning i styrorganet 14 samt var sitt hal 63 i stansdynan 4. Stanspinnama 60, som samverka med de rorliga paverkningsorganen arc darjamte styrda av fjadertradar 64, som utan spelrum dro inforda i hal i resp. stanspinne samt fasta i bryggan 31. The slide member 39 is provided with a groove 42 and two screw holes 43, which means serve to fasten the slide member to the shaft 24 by means of screws 44. The slide member 39 is intended for selective punching in four marking positions on a coder ring 40 and constantly punching in a sixth marking position. positions lie on a straight line, which is preferably perpendicular to the longitudinal direction of the strip, in which the strip is advanced through the perforating device in accordance with the invention. The slide member 39 is provided with a fixed actuating member 46 corresponding to the sixth marking position and with three openings 47 for three movable actuating members 48a, 48b and with two. openings 49 for two movable actuating means 50a, 50b. The actuating means 48 lie in the same vertical plane as resp. stop screws 30, and the actuating means 50 lie in the same vertical plane as resp. stop screws 29. Each actuating means 48, 50 is formed by a pivotable heated angular sea rod, one of which lever arms 48a, 50a is intended to come into abutment against a stop screw 30 resp. 29 and whose second sea arm 48b, 50b forms an anchor, which is coated in the middle of the liner and cooperates with a pair of magnetic cores 19 resp. To form a magnetic circuit. At least the armature forming the armature 48b, 50b is made of magnetic material. All actuating means 48, 50 are pivotally mounted about a common shaft 52, which is fixedly mounted in a bore 53 in the slide member 39. The actuating means 48, which cooperate with the magnetic cores 19, are pre-actuated in the direction away from them, i.e. counterclockwise in Fig. 2, of a spring 54 with three spring tongues, one for each actuating means. By analogy with this, the actuating means 50, which co-operate with the magnetic cores 20, are pre-actuated in the direction away from them, i.e. clockwise in Fig. 2, of a spring 55 with two spring tongues, a conventional actuating means. The two spring frames 54, 55 are fixed by means of screws 56 (Fig. 3) fixed in screw hall 57 (Fig. 4) in the slide member 39. A punching pin 59 cooperates with the fixed actuating means 46, and with each of the swing children actuating means 48, 50 cooperates a punching pin 60. The punching pins 59, 60 are inserted through a hall 61 (Fig. 4) in the slide member 39 and then moved laterally (parallel to their longitudinal direction) in a groove 62 in the slide member until they are aligned with each actuating member 46. , 48 and 50 and each has its own double guide in the guide means 14 and each has its own hall 63 in the punching pad 4. The punch pins 60, which co-operate with the movable actuating means arc therejamte guided by spring trades 64, which without clearance pulled into the hall in resp. punching pin and fixed in the bridge 31.

Perforeringsanordningen i enlighet med uppfinningen fungerar pa fOljande salt: Nar vid huvuddrivaxelns 7 rotation vevstakarna 33, 34 och claimed slidorganet 39 samt de i detsamma lagrade paverkningsorganen 46, 48, 50 rora sig uppat, sla paverkningsorganens 48, 50 havarmar 48a, 50a an mot anslagsskruvama 30 resp. 29, sä att paverkningsorganen 48 och 50 vridas medurs resp. moturs mot inverkan av fjadrarna 54 resp. 55. Harvid komma paverkningsorganens ankarehavarmar 48b, 50b till anliggning mot resp. magnetkarnor 19, 20, varvid ifragavarande ankarehavarmar i stort sett befinna sig rakt ovanfor och i linje med en motsvarande stanspinne 60. Det fasta paverkningsorganet 46 befinner sig alltid i linje med sin stanspinne 59. 201 263 Nu, dvs. ungefar i slidorganets owe vandlage, magnetiseras selektivt en mot den kodade informationen (t. ex. en siffra eller en bokstav) svarande kombination av magneter 17-22, varigenom de mot denna kombination svarande paverkningsorganen 48, 50 fasthallas i kontakt med resp. magnetkarnor 19 resp. 20 i verksamt, stanspinnarna paverkande lage mot inverkan av kraften frail fjadrarna 54, 55. Magneterna i den visade utforingsformen aro namligen icke tillrackligt starka for att draga till sig sina ankarehavarmar 48b, 50b mot inverkan av resp. fjadrar 54 resp. 55, men dal.- emot kunna magneterna fasthalla attraherade ankaren mot fjadrarnas inverkan. De mot de omagnetiserade magneterna svarande paverkningsorganen 48, 50 aterforas daremot genom fjadrarnas 54 resp. 55 inverkan till overksamt lage nar slidorganet 39 vid huvudaxelns 7 fortsatta rotation borjar rora sig nedat, sa att sistnamnda pa.verkningsorgans havarmar 48a, 50a forlorn kontakten med sina anslagsskruvar 30 resp. 29. Nar slidorganet 39 fortsatter sin nedatgaende rorelse under utfOrande av ett stansningsslag, perforeras remsan salunda endast, forutom av den bestandigt verksamma stanspinnen 59, av de stanspinnar 60, vilkas paverkningsorgan 48, 50 fasthallas av de strOmmatade elektromagneterna. De andra stanspinnarna 60 hindras av fjadertradarna 64 frh.'n att deltaga i slidorganets 39 nedatgaende rorelse och rora sig salunda uppat i forhallande till resp. paverkningsorgan 48, 50, vilkas rorelsebanor ligga vid sidan av de overksamma stanspinnarna 60. Sedan slidorganet 39 och de verksamma stanspinnarna 59, 60 slutat sin nedatgaende rorelse och salunda utfort perforering av en kodad rad markeringspositioner, upphor stromtillforseln till elektromagnetema varjamte slidorganet 39 vid huvuddrivaxelns fortsatta rotation fOres uppat igen, varefter det beskrivna forloppet upprepas. Genom att paverkningsorganens 48, omstallning enligt uppfinningen gjorts rent mekanisk (tvangsmassig) i stallet for t. ex. elektromeka.nisk, har perforeringshastigheten kunnat hojas med en faktor 7 a 8, namligen ungefar frau c:a perforeringsrader per sekund till c:a 1rader per sekund. The perforating device according to the invention operates on the following salt: When on the rotation of the main drive shaft 7 when the connecting rods 33, 34 and the claimed slide member 39 and the actuating means 46, 48, 50 mounted therein move upwards, the actuating means 48, 50 strike arms 48a, 50a against the stop screws 30 resp. 29, so that the actuating means 48 and 50 are rotated clockwise resp. counterclockwise against the action of the springs 54 resp. 55. In this case, the anchoring holders 48b, 50b of the impacting means come into contact with resp. magnetic cores 19, 20, the anchor holders in question being substantially directly above and in line with a corresponding punch pin 60. The fixed actuating member 46 is always in line with its punch pin 59. 201 263 Now, i.e. approximately in the owe water layer of the vaginal means, a combination of magnets 17-22 corresponding to the coded information (eg a number or a letter) is selectively magnetized, whereby the actuating means 48, 50 corresponding to this combination are held in contact with resp. magnetic cores 19 resp. The magnets in the embodiment shown are not strong enough to attract their anchor holders 48b, 50b against the action of resp. springs 54 resp. 55, but dal.- against the magnets being able to hold attracted the anchor against the action of the springs. On the other hand, the actuating means 48, 50 corresponding to the unmagnetized magnets are returned through the springs 54 and 54, respectively. When the slide member 39 starts to move downwards during the continued rotation of the main shaft 7, so that the latter arms 48a, 50a of the actuating member lose contact with their stop screws 30 and 30, respectively. 29. When the slide member 39 continues its downward movement while performing a punching stroke, the strip is thus perforated only, except by the permanently active punch pin 59, by the punch pins 60, the actuating means 48, 50 of which are held by the current-supplied electromagnets. The other punching pins 60 are prevented by the spring trades 64 from participating in the downward movement of the slide member 39 and thus move upwards in relation to resp. actuating means 48, 50, the movement paths of which lie next to the inactive punching pins 60. rotation is carried up again, after which the described process is repeated. By making the adjustment means 48, the adjustment according to the invention purely mechanical (forced) in the stable for e.g. electromechanically, the perforation speed has been increased by a factor of 7 to 8, namely from about perforation lines per second to about 1 lines per second.

Det ar givetvis viktigt, att strommatningen av magnetema sker under raft del av varje stansningscykel, dvs. i stort sett under slidorganets nedatgaende rorelse, och darfOr är perforeringsanordningen i enlighet med uppfinningen lampligen utrustad med en synkroniseringsanordning. Derma innefattar i den sasom exempel beskrivna utforingsformen en visare 66, som är fast pa axeln 7 samt atminstone delvis bestar av magnetiskt material och är rorlig genom ett luftgap 671 en magnetisk krets. Den vid visarens 66 passage genom luftgapet 67 uppkommande flodesandringen ger I en ph den magnetiska kretsen anordnad lindDing upphov till en synkroniseringspuls, som lampligen efter forstarkning utnyttjas till att igangsatta stronatillforseln till magnetema 17 -22. It is of course important that the current supply of the magnets takes place during the raft part of each punching cycle, ie. substantially during the downward movement of the slide member, and therefore the perforating device according to the invention is suitably equipped with a synchronizing device. Thus, in the embodiment described as an example, a pointer 66, which is fixed on the shaft 7 and at least partly consists of magnetic material and is movable through an air gap 671, comprises a magnetic circuit. The river change which occurs at the passage of the pointer 66 through the air gap 67 gives rise in a ph in the magnetic circuit to give rise to a synchronizing pulse, which is suitably used after amplification to initiate the strona supply to the magnets 17 -22.

Den beskrivna och pa ritningarna visade utforingsformen är givetvis att betrakta endast sasom exempel och kan till sina detaljer modifieras pa flera satt mom ramen for f151- jande patentansprak. Salunda kunna elektromagnetema 17-22 som av utrymmesskal anordnats i sick-sack pa omse sidor om styrningen 14 ev. anordnas pa samma sida om denna. Vidare kan exempelvis antalet markeringspositioner i en rad vara ett annat an fern, liksom antalet bestandigt aterkommande stanshal kan vara ett annat an ett. The embodiment described and shown in the drawings is of course to be considered only as an example and can be modified in its details in several ways in the context of the following patent claims. Thus, the electromagnets 17-22 arranged by zigzags in zigzags on opposite sides of the guide 14 ev. arranged on the same side of this. Furthermore, for example, the number of marking positions in a row may be different, just as the number of constantly recurring punching halls may be different.
