Abstract

1. Use of a method for the coating of the surfaces of carboard cut blanks with plastic, in which an extruded plastic foil in viscous state is applied directly on both sides onto individual cardboard cut blanks, characterized in that for the manufacture of files or ring binders, small marginal projections of the foils are produced, which are laid against the side- and front faces of the cut blank.

Description

Oppfinnelsen vedrører en fremgangsmåte til belegning av overflater av pappark som tjener til fremstilling av dokumentordnere, ringbøker o.l. med kunststoff. The invention relates to a method for coating surfaces of cardboard sheets that serve for the production of document folders, ring binders, etc. with plastic.

Det er kjent å kasjere pappark som tjener til fremstilling av dokumentordnere e.l. eller å utstyre med et av PVC-folie bestående overtrekk. Sistnevnte påføres i en relativt omstendelig fremgangsmåte, dvs. man går ut fra ferdige folier som ved hjelp av lim sammenklebes med papparkets overflate og sammensveises med hverandre ved kantene. Bortsett fra det nødvendige arbeidsoppbud er det dyrt å måtte anvende ferdige folier som av forarbeidelsesgrunner må ha en bestemt minstetykkelse på minst 180 y. Ved den hittil praktiserte fremstillingsmåte opptrådte dessuten en temmelig høy avfalls-del av den forarbeidede PVC-folie. It is known to dispose of cardboard sheets that serve for the production of document folders etc. or to equip with a cover made of PVC foil. The latter is applied in a relatively cumbersome procedure, i.e. one starts from ready-made foils which are glued together with the surface of the cardboard sheet and welded together at the edges with the help of glue. Apart from the necessary labor contract, it is expensive to have to use ready-made foils which, for processing reasons, must have a certain minimum thickness of at least 180 y. With the production method practiced up until now, there was also a rather high waste portion of the processed PVC foil.

Til grunn for oppfinnelsen ligger den oppgave å tilveiebringe en fremgangsmåte av den innledningsvis nevnte type hvormed det med vesentlig mindre arbeids- og materialoppbud er oppnåelig en til de tidligere belegg i det minste likeverdig belegning av pappark. The invention is based on the task of providing a method of the type mentioned at the outset, with which, with significantly less work and materials required, a coating of cardboard sheet at least equivalent to the previous coatings can be achieved.

Den ytterligere utforming av fremgangsmåten ifølge oppfinnelsen fremgår av trekkene i underkravene. The further design of the method according to the invention appears from the features in the subclaims.

De med oppfinnelsen oppnådde fordeler består iThe advantages achieved with the invention consist in

at kunststoffolien kan påføres umiddelbart uten anvendelse av en kleber fordi den ennå seigtflytende ekstru-derte folie forbinder seg godt med pappoverflaten, that the plastic film can be applied immediately without the use of an adhesive because the still viscous extruded film connects well with the cardboard surface,

at det som utgangsmateriale for folien lar seg anvende et etter ønske innfargbart polyetylen- eller polypropylengranulat, og that a polyethylene or polypropylene granulate that can be colored as desired can be used as the starting material for the foil, and

at det lar seg virkeliggjøre en belegningstykkelse på langt under 80 y, eksempelvis 50 y, hvorved materialfor-bruket er meget lite. Det bortfaller dessuten det PVC-avfall som fremkommer ved den kjente fremstillingsfremgangsmåte, dvs. innsveising av pappark i PVC-folie. that it is possible to realize a coating thickness of well below 80 y, for example 50 y, whereby the material consumption is very small. In addition, the PVC waste produced by the known production method, i.e. welding of cardboard sheets in PVC foil, is eliminated.

Fremgangsmåten ifølge oppfinnelsen fremgår klart av kravene. Til gjennomføring av fremgangsmåten er det anvend-bart kjente på egnet måte modifiserte ekstruderingsinnret-ninger med bredslissdyse eller dyser. The method according to the invention is clear from the claims. For carrying out the method, known and suitably modified extrusion devices with a wide slot nozzle or nozzles can be used.

Claims (4)

1. Fremgangsmåte til kunststoffbelegning av overflater av pappark som tjener til fremstilling av dokumentordnere, ringbøker o.l., karakterisert ved at på de enkelte pappark enten samtidig eller i rekkefølge på begge sider påføres umiddelbart en ekstrudert kunststoffolie i tilstanden av seigtflytende, idet det frembringes små kantfremspring som legges på side- og frontflåtene av arket.1. Method for the plastic coating of surfaces of cardboard sheets used for the production of document folders, ring binders etc., characterized by the fact that an extruded plastic film is immediately applied to the individual cardboard sheets either simultaneously or in sequence on both sides, in the state of a viscous liquid, as small edge protrusions are produced which is placed on the side and front rafters of the sheet. 2. Fremgangsmåte ifølge krav 1, karakterisert ved at anlegg av kantfremspring foretas ved på-blåsing ved hjelp av varmluftstrøm.2. Method according to claim 1, characterized in that the installation of edge protrusions is carried out by blowing on with the help of a hot air stream. 3. Fremgangsmåte ifølge krav 1, karakterisert ved at anlegget av kantfremspringene foretas ved hjelp av påtrykningsruller.3. Method according to claim 1, characterized in that the installation of the edge protrusions is carried out using pressure rollers. 4. Fremgangsmåte ifølge krav 1, karakterisert ved at det som materiale for kunststoffolien an-vendes polyetylen- eller polypropylengranulat.4. Method according to claim 1, characterized in that polyethylene or polypropylene granules are used as material for the plastic film.
