2) First fix the tail end of the zipper (lower stop end) on the fixed point A (the pull tab faces inward): b) Fix the pull tab on the pull tab:
) Fix the front end of the zipper (the upper stop end is fixed on points D and B d) Loosen the fixed point A, pull the tail of the zipper upward so that the zipper falls in the middle of the hole of the balance plate, and then adjust point A (at this time, point D is already fixed and point B is on the level surface); e) Loosen the horizontal supports B and C, and put the fabric tapes on both sides of the zipper into the clamps B and C, with a clamping size of about 5mm. At this time, the five fixed points are fixed; adjust the tensioner to the upper limit, loosen the pull tab to see if the zipper maintains its straight line.
