I'm looking for an idiom for “producing multiple (near) identical instances of something in rapid succession”. Ideally it would be colloquial and/or humorous. Do you know any?
Edit: Its intended use is to illustrate in a succinct manner the purpose of some piece of computer software that produces many documents, similar to a mass mailing. In German, we have e.g. “vom Fließband” and “am laufenden Band”, both referring to a conveyor belt in a factory.
Edit 2: I'm thinking about something advertising-like, it would be something like “[product name] – [it gives you] [special type of document] [idiom for ‘many of them in rapid succession’]”
Edit 3: I found cookie-cutter, which seems nice, but I think its main use is perjorative
