Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome

Spindle fibers form during mitosis.
during metaphase not sure how
centrioles
.
Prophase
I believe that they are formed by the Centrioles in the cell. These centrioles are found inside (encased) in the centrosomes. They combine microtubles and associated proteins (such as Aurora A) to strengthen the spindle fibers.
when there is tripolar spindle fiber the chromosomes are likely to have 3 spindle lines making the chromosomes split into each other.

kinetochore microtubules bind with spindle fibers.
Spindle fiber is made of clusters of aggregated microtubules. The spindle fibers will form at opposite poles of a cell during the prophase in mitosis.

Spindle Fibers are formed between centrosomes. Centrosomes migrate to opposite ends of the cell during cell division. The spindle fibers function is to anchor the centrosomes and chromosomes into the poles. The chromosomes then reel them selves in using the spindle fiber.
