Stranding machine

from Wikipedia, the free encyclopedia
Stranding machine. The single wires are fed in from the left, the twisted cable on the right.

A stranding machine , also known as stranding machine , is an apparatus with which individual wires are twisted or stranded to form wire ropes or, in the case of electrical lines, from several strands to form electrical cables .

Working principle

The machine consists of a bobbin around which a rotor with the individual wires moves. Several individual wires are twisted to form a strand, the shape of which is determined by the number of individual wires. The speed of the rotor determines the length of the lay . These two factors together determine the shape of the final cable.

Types

A basic distinction is made between single and double lay machines. Single impact machines generate one impact on the cable per rotor revolution. Their advantage is the often low material stress . A disadvantage is their slower production speed compared to the double-lay machine. Double lay machines produce one stroke on the entry side and one on the deflection side per rotor revolution at a higher production speed.
