Knitting a pouf ...question

This pattern states to knit in wedges. I did the pattern 1 thru 28 …do I continue to knit 1-28 without binding off? Or do I knit 1-28 and bind off each time 10 more times?? I’m on the 3rd time of repeating the rows, I’m just worried bc I don’t see any wedges??

It should be approximately football shaped sections. Don’t bind off but continue with the next section.
The shaping is worked by short rows so that there are more rows of knitting in the middle of the piece than at the ends. This shapes the sections.
