Instruction for unwinding reinforcing strands (ropes)
Coils of reinforcing strands (ropes) are marked with a paper self-adhesive label with the image “arrow” to indicate the direction of unwinding of the strand in the following order (Figure 1):
– On the reinforcing strands (ropes) of the right twist, the arrow is directed inside the coil;
– On reinforcing strands (ropes) of the left twist, the arrow points outward of the coil.
Figure 1 Direction of unwinding of a strand (rope)
To avoid tangling of strands (ropes) during their processing, it is necessary to unwind a reinforcing strand (rope) depending on the direction of stranding (rope) in the direction indicated by the arrow (Figure 1).
The dimensions and properties of the strands according to ST 009-2011 and agreement AT 021-01/006-2023.
