taittumina

Taittumina is a Finnish term that refers to the act or state of folding, bending, or creasing. It is used primarily in technical contexts to describe how materials or structures acquire their folded forms, whether through manufacturing processes, mechanical action, or intentional design.

Etymology and scope. The word stems from the Finnish verb taittua, meaning to bend or fold, with a nominalizing element that yields a term for the process or phenomenon. In everyday language it may be uncommon, but in engineering, design, and related fields taittumina appears in discussions of how surfaces or components develop folds, creases, or hinge lines.

Applications and contexts. In sheet metal work, taittumina denotes the creasing or bending along predefined lines to create three-dimensional shapes from flat sheets. In textiles and papermaking, it describes folding sequences and crease patterns that determine the final form of a fabric or page. Architectural and product design literature may use the term to discuss fold-based strategies, including origami-inspired structures or deployable systems. In these contexts taittumina often implies a controlled, repeatable deformation rather than random buckling.

Relation to related terms. Taittua and taitto are related Finnish terms dealing with bending and folding, while taittuminen or taittuminen commonly denote the process of bending or folding in different linguistic or technical contexts.
