Description

Technical Field

[0002] The two sides of different-plane beads have different shapes, such as a flat surface and a flower-shaped surface with a specific shape. When sewing or embroidering is required, the crystals need to be uniformly oriented with one side facing up and penetrated through the bead guide rod.

The mounting frame 1 can be a mounting plate or a mounting block. The non-coplanar beads to be directionally output can be placed on the barrel chassis 2 inside the barrel wall 3 and rotate with the rotation of the barrel chassis 2.
