This factory is known as factory of factories. This pattern comprises of a super-factory which in turns create other factories.
In the example codes given here, I am providing a credit card creation application.
In the CreditCardFactory.java file, we create new credit card factory, either AmexFactory.java or VisaFactory.java, based on the credit score, but none of the classes has any idea about the implementation of the other class. Again, we create another factory inside of those classes. So, there's a chain of factory, where CreditCardFactory.java is the super factory which creates other factories eventually.
