An 1829 encyclopaedia article on weaving that opens with a dictionary-style definition of the verb 'weave' and literary quotations. It then describes Mr. Roberts of Manchester's patented improvements to the power loom, including a tappet mechanism for six-shaft twill looms, a cylinder-and-needle device for figured weaving (an alternative to the draw boy), and cloth take-up and warp let-off regulation. It also covers multi-shuttle arrangements for ribbon looms. Two engraved plates show the loom mechanisms.
