Extractor systems for extracting a flexible article of manufacture from a mold include an extraction roller, at least one track configured to support the extraction roller, and a trolley configured to carry the extraction roller from a first side of the mold toward a second, opposite side of the mold. Molding systems include a mold and an extractor system. Methods of extracting a flexible article of manufacture from a mold include separating a first platen and a second platen, positioning an extraction roller between the separated first and second platens, engaging the article of manufacture with a row of teeth positioned along the extraction roller, and rotating the extraction roller to wrap the article of manufacture about the extraction roller.

An injection mold for molding a flip-top closure having a body portion and a lid attached to the body portion by a living hinge has first and second mold portions for defining first and second portions of the flip-top closure respectively, a lid closing tool for closing the lid of the flip-top closure on the body portion after a molding of the flip-top closure in the injection mold and before an ejection of the flip-top closure from the injection mold, and first and second linear actuators operatively connected to the lid closing tool for moving the lid closing tool about first and second axes respectively. The first and second linear actuators are controllable to move the lid closing tool along a lid closing path for closing the lid. An in-mold lid closing device and a method for making a flip-top closure are also disclosed.
