CLASS INTERNATIONAL SWEDISH B 41 d15 c: 3/02 PATENT AND REGISTER OF THE SWEDISH Ans. 10 546/1959 was received on 10/11 1959 issued on 11111 1963 PB FAUGLI, I 0 FAUGLI and U HEGSVOLD, OSLO, NORWAY Procedure and arrangement for removing from cylindrical stereotype pressure plates or plates the parts which are not to be used for printing The present invention relates to a dye, cast and. a device may remove those parts of cylindrical steretotype pressure plates or plates which are not to be used for printing. Previously, this work has been carried out in such a way that the pressure plates are clamped in a machine, and the said parts have been removed by milling. This work requires an ordinary person to operate the machine and the work is time consuming and must be carried out with great care, which makes it expensive.

Uppfinningen har till andamal att astadkornma ett Mdatingsatt och en anordning far .att automatiskt avlagsna namnda delar far att harigenora inbespara kostnader vid man,uell betjaning av maskinen. D.etta sker enligt uppfinningen genom att minst tva lika tryckplattor eller Tatar fastspannas pa en cylinder, och att de delar som icke skola avlagsnas, farses med ett skikt, som vid cylindems rotation avsakes av en anorchting vii-ken styr ett frasverktygs rorelse till och fran arbetslaget, sa att plattorna medelst belagget tjana sasom mall for varandra, i det att en platta passerar forbi avsalmingsanorciningen .samtidigt som en ann,an, platta p.asserar foal frasverktyget. The object of the invention is to provide a computer and a device which can automatically remove said parts and thereby save costs in the operation of the machine. This is done according to the invention by clamping at least two identical pressure plates or Tatars on a cylinder, and that the parts which are not to be removed are milled with a layer which, when the cylinder rotates, is cut off by an anorch which controls the movement of from the work team, said that the plates by means of the coating serve as a template for each other, in that one plate passes past the desalination anorcination, at the same time as another, another, plate passes the foal phrase tool.

En anordning fOr utforande av detta arbete kannetecknas av att skiktet är elektriskt isolerande, och att avsokningsanordningen be-star av en kontaktarm, som star i Mewing med plattorna och forskjutes utmed en skruvlinje pa plattomas yta, varvid kontakten brytes vid passagen av skikten oeh harvid manavrerar en elektromagnet, vilken, bringar frasverktyget fran dess arbetslage. En annan anordning far utforande av detta arbete kannetecknas av att skiktet liar andra ljusreflekterande ,egenskaper an plattornas ovriga del och att avsokningsanordningen besth av en ljus kaLla och en fotocell, som avsoker plattorna langs en skruvlinje vid cylinderns rotation, ochosom vid passagen av skikten mano-vrerar en elektromagnet, vilken bringar frasverktyget ut Iran dess arbetslage. A device for carrying out this work can be characterized in that the layer is electrically insulating, and that the scanning device consists of a contact arm which stands in Mewing with the plates and is displaced along a helix on the surface of the plates, the contact breaking at the passage of the layers and maneuvering. an electromagnet, which, brings the milling tool from its working position. Another device for carrying out this work may be characterized in that the layer has other light-reflecting properties on the other part of the plates and that the scanning device consists of a light source and a photocell which scans the plates along a helix during the rotation of the cylinder, as well as during the passage of the layers. an electromagnet, which brings the phrase tool out of Iran its working class.

En tredje anordning for utfOrande av ifragavarande arbete kannete,cknas av att skiktet är magnetiskt, och att avsokningsanordningen besth av ett magnetiskt avsakningshuvud, som vid cylinderns rotation avsoker plattorna langs en skruvlinje, och som vid passagen av skikten manavrerar en elektromagnet, vilken bringar frasverktyget ut Iran dess arbetslage. En, .fjarde anordning ,for utfarande av arbetet kamietecknas av att skikten ha sadan tjoeklek, att ett mekaniskt avkarmingsorgan, som vid cylinderns rotation avkanner plattorna longs em skruvlinje vid passagen. av skikten upplyftes, oeh manovrerar en kontakt i en elektromagnets aktiveringskrets, sa att elektromagneten, bringar frasverktyget ut Iran dess arbetslage. utforingsform av en anordning enligt uppfirmin,gen .skall au beskrivas under hanvisning till bifogade ritning, dar fig. 1 visar en anordning Mr utfarande av forfaringssattet enligt anordningeii sett framifran, medan fig. 2 visar samma anordning sedd, fran sidan. A third device for performing the work in question can be characterized in that the layer is magnetic, and that the scanning device consists of a magnetic cutting head, which scans the plates along a helix during the rotation of the cylinder, and which maneuvers an electromagnet when passing the layers, which brings out the milling tool. Iran its working class. A fourth device for carrying out the work is characterized in that the layers have such a thickness that a mechanical frame member, which upon rotation of the cylinder scans the plates along a helical line at the passage. of the layers is lifted, oeh maneuvers a contact in an electromagnet's activation circuit, so that the electromagnet, the phrase tool brings Iran its working class. embodiment of a device according to the invention will be described with reference to the accompanying drawing, in which Fig. 1 shows a device according to the method set according to the device seen from the front, while Fig. 2 shows the same device seen from the side.

Pa en roterbar cylinder A Ore tva stereotypitryckplattor B fastspanda. Delar C pa tryekplattorna, som icke skola frasas bort, arc belagda med ett elektriskt isolerande skikt. En avkannande eller avsokande kontaktarm D Or anordnact att vid cylinders rotation a-vkanna tryckplattornas yta utmed en skruvlinje. Da kontaktarmen, som Or inkopplad i aktiveringskretsen for en elektromagnet E, passerar farbi de elektriskt isolerade delarna C, brytes stromkretsen genom amen och valsen, och over en manoverarm F briogas fras- 2— — spindeln G med frasstalet ut ur arbetslaget, sa att delen C pa den byre plattan B pa ritningen, motsvarande delen C pa den. nedre plattan B pa ritningen, icke bearbetas dä kontakten med den nedre plattan ar bruten. On a rotatable cylinder A Ore two stereotype pressure plates B clamped. Parts C of the pressure plates, which are not to be milled away, are coated with an electrically insulating layer. A scanning or scanning contact arm D Or is arranged to, when the cylinder rotates, a-scan the surface of the pressure plates along a helical line. When the contact arm, which Or is connected in the activating circuit for an electromagnet E, passes through the electrically insulated parts C, the circuit is broken by the amen and the roller, and over a control arm F the gas spindle G with the milling number out of the working layer is said to C on the byre plate B on the drawing, corresponding to the part C on it. lower plate B in the drawing, is not machined when the contact with the lower plate is broken.
