During the production of cardboard food cans, the packaging bottom and the cylindrical wall are joined in the seaming process. In order to achieve a high-quality, crack-free surface of the cardboard seam, low friction between the seaming chuck and the cardboard must be ensured. The goal of this study was to minimise the friction between the seaming chuck and the cardboard can surface.,Tribological properties of the seaming chuck were optimised by adjusting its material properties, surface topography and surface energy followed by measurements of the resulting friction response in sliding contact with a representative paper sample.,A strong correlation between the surface free energies of the tribological samples and their measured coefficients of friction was observed, indicating that in tribological tests, adhesion was the dominating friction mechanism. Furthermore, the fact that the smoother samples yielded higher friction values than the rougher ones is most likely also correlated with the higher adhesion of the smoother samples originating from their larger contact area.,The existing results indicate that for tribological optimisation of paper and cardboard contacts primarily the adhesive friction component should be considered – by either reducing the surface free energy of the counter-body or optimising its surface topography.,By applying the selected solution concept, a friction reduction of more than 50% as compared to the benchmark was achieved.,The present study provides a guideline for tribological optimisation of paper and cardboard contacts.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-02-2020-0064/

纸板罐封口夹头的优化——第 1 部分：表面工程和摩擦学评估

在纸板食品罐的生产过程中，包装底部和圆柱壁在接缝过程中连接在一起。为了获得高质量、无裂纹的纸板接缝表面，必须确保接缝夹头和纸板之间的摩擦力低。本研究的目标是最大限度地减少封口夹头和纸板罐表面之间的摩擦。,通过调整其材料特性、表面形貌和表面能，然后测量滑动时产生的摩擦响应来优化封口夹头的摩擦学特性与代表性纸样品接触。观察到摩擦学样品的表面自由能与其测量的摩擦系数之间存在很强的相关性，表明在摩擦学测试中，粘附是主要的摩擦机制。此外，更光滑的样品比粗糙的样品产生更高的摩擦值这一事实很可能也与源于它们更大的接触面积的更光滑样品的更高附着力相关。现有结果表明，对于纸和纸板接触的摩擦学优化主要应考虑粘附摩擦组件——通过降低配对体的表面自由能或优化其表面形貌。,通过应用选定的解决方案概念，与基准相比，摩擦减少了 50% 以上.,本研究为纸和纸板接触的摩擦学优化提供了指南。本文的同行评审历史可在以下网址获得：https://publons.com/publon/10。
