Multiple copies of same fields with different data across pages

I have tried numeous searches to find this, and have been unable to locate an answer. 

If I want to create a form that has (for example) mail labels...how can I do that?

Name
Address
City, State zip

Name 
Address
City, State zip
...
At the end of the page, I want user to be able to add another page to add even more names and addresses.

I know I can name them

Name1

Address1

City1, State1 zip1

Name2

Address2

City2, State2 zip2

...

Even doing that...how do I allow user to add a duplicate of that page to start a new list?

This is a blamk form that I would provide for public use (not internal) that is dowloaded from a web site or sent via email.
