What is the wooden frame used in paper-making called?

In the context of paper-making, the wooden frame used in the process is known as a deckle. The deckle serves a crucial role in shaping the paper and ensuring that the freshly made pulp maintains a uniform thickness and size as it drains and dries. It is typically used in conjunction with a mold; together, they create a screen that holds the pulp while excess water is removed.

The concept of the deckle is fundamental in traditional paper-making techniques, where artisans use it to create sheets of paper from a wet pulp mixture. The edges of the deckle can also affect the final appearance of the paper, sometimes giving it a handmade quality with deckle edges that are not perfectly straight, which is often desired in fine art and stationery production.

Other options do not pertain to the role of shaping or forming paper in paper-making. For instance, a raster typically relates to the structure of images, a loom is used in weaving textiles, and a template is generally a guide for designing or cutting other materials. Understanding the function of the deckle in this context is essential for grasping the traditional methods of creating paper.
