How do I remove webforms from content types?
If you use the webform module (I'm not 100% sure from your question), and you want to disable the webform functionality for the content type, then you can do this on the settings page of the content type (Admin > Structure > Content types). There should be a a fieldset or vertical tab called "Webform", and when you click on that there should be a checkbox that you can disable.



But be aware that this removes the form from all previously created nodes too, not only for the new ones.

If you're not using webform then please specify what modules do you use so that we can understand how this functionality is build into your site.
