Beating (assembling process)

Any of various assembling techniques that press additions firmly onto finished parts. In the context of bookbinding, the process of flattening the leaves or gatherings of a text block before sewing or stitching by striking them repeatedly with a beating hammer, in order to compress and flatten them, or, in rebinding, to remove the backing shoulders. Similarly, in the context of weaving or similar activities, the process of using a beater or comb to press each new weft into correct position against existing wefts.
