Konstruktionskoncept till att skapa wellpappsprover i laboratoriemiljö / Construction concept to create samples of corrugated cardboard in laboratory environment

Gussman Lennström, Anton, Lundberg, Selma January 2022 (has links)
Kraftliners är något som används till att skapa bland annat ytskiktet till pappersprodukten wellpapp. Wellpapp består av ett lager kraftliner på antigen en- eller vardera sidan av ett vågigt papper, kallat flute. På uppdrag av SCA R&D undersöker detta kandidatarbete möjligheten till att skapa en konceptuell prototyp till en maskin som kan konstruera wellpappsprover på deras laboratorium. Detta för att via tester kunna prediktera hur variationer i wellpappens struktur påverkar dess egenskaper. Arbetet utfördes med hjälp av en iterativ metod där koncept först togs fram och sedan utvärderades repetitivt tills ett slutgiltigt koncept var framtaget. Konceptframtagningen bestod av fem iterationer med faserna konceptgenerering, modellering, prototypframtagning, tester av prototyp och utvärdering. Arbetet resulterade i ett slutgiltigt koncept som ledde till en illustrerad prototyp i mindre skala som visar hur wellpappsprover skulle kunna skapas i SCA’s R&D-laboratorium. / Kraftliners are used to create, among other things, the surface layer for the paper product corrugated board. Corrugated board consists of a layer of kraftliner on either one or both sides of a wavy paper, called flute. On behalf of SCA R&D this bachelor's thesis investigates the possibility of creating a conceptual prototype for a machine that can create corrugated board samples in their laboratory. This is to be able to predict, via tests, how variations in the structure of the corrugated board affect its properties. The work was carried out using an iterative method where concepts were first developed and then evaluated repetitively until a final concept was developed. The concept development consisted of five iterations with the phases of concept generation, modeling, prototype development, prototype testing and evaluation. The work resulted in a final concept that led to an illustrated prototype on a smaller scale that shows how corrugated board samples could be created in SCA's R&D laboratory.
