PFrames > how to get them all at same orientation (not rotated)

hi,
when i create perp frames along a curve , they get rotated from node to node (green in image 1)

is there a way to get them all at the same orientation (while tey remain perpendicular at every node) ? (red in image 2)

goal: project a curve to the first frame at each curve and get a oriented sweep / extrusion).

thanx

stan
