DIRECTION OF UNCOILING
For the creation of new articles, this important detail must be specified. The direction of uncoiling can be:
- a) Clockwise (standard). When the coil is in a horizontal position, the tube ending in the inner layer of the coil is at the bottom.
- b) Anti-clockwise (optional). When the coil is in a horizontal position, the tube ending in the inner layer of the coil is at the top.
