Well there are two different ways to achieve your requirement.
1. You can break a long form and create a multi-page form by adding "Page Break" field in your existing form. If you set the signature widget mandatory, user will have to sign it before going to the next page. The following guide should help you: http://www.jotform.com/help/119-How-to-Create-Multi-Page-Forms
2. Another option is to redirect your user to next page when the first form is submitted successfully. The following guide should help you on how to redirect to another page : http://www.jotform.com/help/38-Redirecting-Users-to-a-Different-Page
