Clothing production in historical contexts (including Roman) is usually a household activity. This mostly means it's done by women of all classes, if only perhaps as a show of virtue. A glove-making device, as a personal item, might show up randomly any place they were used.

Conspicuously expensive household items would also not be unknown. It makes some sense that the bronze survivors may be those owned by wealthy women, where the bulk of those used may be (unlikely to survive) wood.
