Description

Uppfinnare: C Vifloresi Uppfinningen avser ett for forpackningsandamal anvandbart reliefpapper. Reliefpapper enligt uppfinningen utmarkes av en ny kom- bination av var for sig Janda anordningar, varigenom ett alster erhallits, som uppvisar egenskaper, varigenom det formanligt skiljer sig fran tidigare kanda for forpackningsandamat avsedda reliefpapper. Inventor: C Vifloresi The invention relates to a relief paper usable for packaging purposes. Relief paper according to the invention is marked by a new combination of separate Janda devices, whereby an article is obtained which exhibits properties, whereby it differs from previously known relief paper intended for packaging purposes.

Vellpapp med tfickskikt av vanligt utforande ar styv, men utan tackskikt daremot icke motstandskraftig mot hoptryckning av de vagformade upphojningarna. Det finnes aven kartong eller plattor, vilka hava zickzackartat forlopande upphojningar med plana ytor, som tj dna till att Oka motstandsformagan mot hoptryckning och/eller Oka kartongens eller plattornas styvhet. Corrugated cardboard with a tapered layer of ordinary design is rigid, but without a tapered layer, but not resistant to compression of the wavy ridges. There are also cartons or plates, which have zigzag-like extending elevations with flat surfaces, which serve to increase the shape of the resistance to compression and / or increase the stiffness of the carton or plates.

Till skillnad harifran avser foreliggande uppfinning ett fOr forpackningsandamal an- vandbart reliefpapper, som ehuru det saknar tackskikt och bestar av en pappersbana i ett eller flera skikt, samtidigt ar mycket motstandskraftigt mot hoptryckning av upph5jningarna och bojligt och tanjbart. In contrast, the present invention relates to a relief paper usable for packaging purposes, which although it has no thank-you layer and consists of a paper web in one or more layers, is at the same time very resistant to compression of the elevations and flexible and stretchable.

Uppfinningen bestar dari, att upph5jningarna forlopa i zickzackformade linjer paral- lellt med varandra, mellan vilka papperet är bojligt och vikbart Fangs raka vikningslinjer, att upphojningarna hava plana ytor och lamp- ligen ett i och for sig Hirt trapetsformat tvar- snitt, och att papperet ãr elastiskt tanjbart i langdriktningen darigenom, att relieflinjerna efter papperets pragling hava forts narmare varandra genom sammantryckning av papperet pa i och for sig kfint satt pa tvaren i farhallande till relieflinjerna. The invention consists in that the elevations run in zigzag-shaped lines parallel to each other, between which the paper is flexible and foldable. is elastically extensible in the longitudinal direction in that the relief lines after the embossing of the paper have continued closer to each other by compressing the paper on itself in a nice way in relation to the relief lines.

Papperets motstandsformaga mot nedpressning av upphojningarna ãr ernadd genom den I och for sig kanda utbildningen av relieferna i form av zickzack-artat forlopande upphöj- ningar och fordjupningar med plana ytor. Papperets bojlighet a uppratthallen darigenom, att de zickzackartat forlopande relieflinj erna aro parallella och sa anbragta intill varandra, att det mellan tva narliggande relieflinjer erhalles en rak vikningslinje, sa att relieflinjerna salunda joke ingripa i varandra. Papperets tanjbarhet är slutligen astadkommen darigenom, att papperet efter praglingen av de parallella relieflinjerna hoptryckts i en mot dessa linjer vinkelrat riktning, varigenom avstanden mellan relieflinjerna minskats °oh papperet blivit elastiskt tanjbart i langdriktningen, utan att dess ovriga egenskaper paverkats. The paper's resistance to compression of the elevations is achieved through the per se known formation of the reliefs in the form of zigzag-like continuous elevations and depressions with flat surfaces. The flexibility of the paper in the upright hall is such that the zigzag-extending relief lines are parallel and so arranged next to each other that a straight fold line is obtained between two adjacent relief lines, so that the relief lines will interlock jokingly. The extensibility of the paper is finally achieved by compressing the paper after the embossing of the parallel relief lines in a direction perpendicular to these lines, whereby the distance between the relief lines is reduced and the paper becomes elastically extensible in the longitudinal direction, without affecting its other properties.

Pa bifogade ritning visas i fig. 1 till 3a tva utforingsformer av reliefpapper enligt uppfinningen, under det att fig. 4 och 5 schematiskt visa en anordning for reliefpapperets framstallning. In the accompanying drawing, Figs. 1 to 3a show two embodiments of relief paper according to the invention, while Figs. 4 and 5 schematically show a device for the production of the relief paper.

Fig. 1 och 2 visa den forsta utforingsformen av reliefpapperet, i plan och langdseklion respektive, i ett mellanstadium av framstallningen, sedan upphojningarna och f Ordjupningarna praglats. Fig. 1 askadliggor relieflinjernas zickzackform och fig. 2 visar upphojningarnas trapetsartade tvarsnittsform. Fig. la och 2a visa, likaledes i plan och langdsektion respektive, det praglade papperet i fardigt skick efter dess sammantryckning i langdriktningen, dvs. i en mot relieflinjerna vinkelrat riktning. Figs. 1 and 2 show the first embodiment of the relief paper, in planar and longitudinal cleavage, respectively, in an intermediate stage of the production, after the elevations and f The word depressions have been praglated. Fig. 1 shows the zigzag shape of the relief lines and Fig. 2 shows the trapezoidal cross-sectional shape of the elevations. Figs. 1a and 2a show, likewise in plane and longitudinal section, respectively, the embossed paper in finished condition after its compression in the longitudinal direction, i.e. in a direction perpendicular to the relief lines.

Fig. 3 och 3a visa i plansektion den andra utforingsformen efter upphojningarnas och fordjupningarnas pragling, innan respektive efter det att det praglade papperet sammantryckts i en mot relieflinjerna vinkelrat riktning. Vid denna utforingsform hava zickzaeklinj ernas toppar en avplanad form. Figs. 3 and 3a show in plan section the second embodiment after the embossing of the elevations and depressions, before and after the embossed paper has been compressed in a direction perpendicular to the relief lines. In this embodiment, the tops of the zigzag lines have a flattened shape.

Papperet enligt fig. la och 2a kan fram- 2— stallas med tillhj alp av den i fig. 4 och 5 schematiskt visade anordningen. Demia bestar av tva. prdglingsvalsar, vilka best& ay en ihalig cylinder 2 med lagertappar 1 oeh 5 vid andar-, na och ay ett antal pa dessa cylindrar fasta skivor 3, som runt omkretsen hava snett stallda -Lander 4. Dessa skivor 3 aro sa anordnade, att deras Under aro omvaxlande snedstalkla at hager och vanster. Bet d.jup, med -vilket prdglingsvalsarnas-tander ingripa i yarandra, anpassas efter tjockleken av den av ett eller flera skikt bestaende pappersbanan, som skall omvandlas till reliefpapper. Pra.glingsvalsarnas ihaliga cylindrar kunna upphettas elektriskt eller medelst anga. Sedan pappersbanan passerat mellan praglingsvalsarna, varvid den erhallit parallellt med varandra forlapande zickzackformade relieflinjer, sammantrycks pappersbanan i langdriktningen, dys. i en riktning, som är vinkelrat mot reliflinjerna, t. ex. ddrigenom att pappersbanan pa i och for sig kant salt fares fram mellan tya pressplattor 6 (fig. 5). The paper according to Figs. 1a and 2a can be produced with the aid of the device schematically shown in Figs. 4 and 5. Demia consists of two. Bearing rollers, which consist of a solid cylinder 2 with bearing pins 1 or 5 at the ends, and a number of fixed discs 3 on these cylinders, which around the circumference are obliquely arranged -Lander 4. These discs 3 are so arranged that their Under aro alternating oblique stalk at hager and vanster. The depth with which the teeth of the embossing rollers engage with each other is adapted to the thickness of the paper web consisting of one or more layers, which is to be converted into relief paper. The hollow cylinders of the baffle rollers can be heated electrically or by means of steam. After the paper web has passed between the embossing rollers, whereby it has obtained parallel zigzag-shaped relief lines, the paper web is compressed in the longitudinal direction, nozzle. in a direction perpendicular to the relief lines, e.g. in that the paper web on the per se edge of salt is advanced between thick press plates 6 (Fig. 5).

Papperet enligt fig. 3 och 3a kan framstallas med samma anordning med den andringen, att mellan vale par av skivor med at motsatta hail snedstallda -Under insattes en skiva med raka Mader. The paper according to Figs. 3 and 3a can be produced with the same device, with the change that between selected pairs of discs with the opposite hail inclined -Under a disc with straight Mader is inserted.
