The invention includes a method and device for conveying pre-printed polymer oblates (IML), supplied in a roller, to a casting machine such as an injection press that molds items such as cups or lids, where the oblates must be integrated in items by the oblates being partially punched such that they remain fixed to the roller in points or bridges, after which the roller with the semi-punched oblates is placed on a device (1) from which the roller with oblates is rolled out in stages, such that the oblates pass through a tool (5) with holes (9) which are shaped to fit the circumference of the oblates, after which the oblates are removed with a device such as a robot with vacuum suction that tears over the river bridges that fix the oblate to the roller and transfers the oblates to the injection casting tool.
