Maybe I'm misunderstanding you, but I think
`org-clone-subtree-with-time-shift' already does this.  Or do you need
to change the name of the headline?

Here's an example:

(with-temp-buffer
  (insert "* class
<2014-10-22 mié 13:00-15:00>")
  (goto-char (point-min))
  (org-clone-subtree-with-time-shift 5 "+1w")
  ;; ignore this
  (let ((str (buffer-string)))
     (set-text-properties 0 (length str) nil str) str))
=> 
"* class
<2014-10-22 mié 13:00-15:00>
* class
<2014-10-29 mié 13:00-15:00>
* class
<2014-11-05 mié 13:00-15:00>
* class
<2014-11-12 mié 13:00-15:00>
* class
<2014-11-19 mié 13:00-15:00>
* class
<2014-11-26 mié 13:00-15:00>
