Let's break it down into smaller parts and see how that works out --
*[Kfb, k3, ssk, - that starts with 6 sts and you end up with 6
turn, sl 1, k4] - that uses 5 of the 6 sts.
do that 3 times, it doesn't say to turn so I don't think you turn after the k4. Repeat everything in the  3 times. So then you do the next 6 sts, turn and work 5 over that, work 6 sts, turn and work 5 sts. Then it's " kfb, k3, ssk;" that's over the next 6 sts, and then you repeat from * which is the beginning of this sequence.
A link to the pattern or a picture of what it's supposed to look like would be really helpful.
