This new machine developed by SIMA Group represents an important novelty in the field of rope layers, because 280/4 is suitable to produce small diameters, from 2 to 6mm, without investing high capitals, therefore with the max economical conveniennce.

The 280/4 is made of a feeding section, running with 3 or 4 strands, and of a take-up section, which is the GS2016, a more than tested machine.
The system conceived in this way leaves complete freedom to the customer concerning its use, because it is evident it can be used as a rope layer or, using the only take-up section, as a twister.

The 280/4 runs on the principle of the 2 twists in the feeding section and 2 twists in the take-up section; mechanically speaking, cynematism where introduced, which have been considerably simplified, with benefits to the noise level, which is within what foreseen by the international regulations, thanks also to the insulation.

ADVANTAGES:

• Set-up of 280/4 through the control panel of GS2016
• Electronic change of the pre-twist ratio
• Device to detect the strand breakage
• Immediate change of the rotation direction S or Z
• New cynematism with consequent noise reduction
• Feeding up to 3x4 bobbins of 12" x 12", for a total of 160000 den
