Background In the field of glove manufacturing, knitted gloves are widely used because of their good basic flexibility. In order to further improve the protective performance, such as anti-skid, oil-resistant, puncture-resistant and the like, a layer of polymer adhesive layer is generally coated on the surface of the knitted glove, so that the labor protection glove with flexibility and functionality is manufactured. In the glue injection production process, the knitted glove needs to be sleeved on a hand mould with a specific shape at first to form a fixed three-dimensional form, so that the subsequent processes of dipping, glue dripping, vulcanization and the like are facilitated.
