The machine, no matter which design, is capable to contain on the creel four or eight beams on cylindrical disk bobbins. The strings from beams go through the string shortage detectors. The string shortage is signalled with sound and light.

The string is wrapped several times over the positive feeding roller system. Behind the positive feeding rollers, the compensators with 2 following functions are situated:

When in lower position, they provide a string reserve for the injection moulding press and in their upper position, they make the string to be clamped on the positive feeding rollers, thus to be wound off the take-off rollers.

On the machine outlet, the disk stretchers are situated that keep the string which enters the injection moulding press tight.

The machine is equipped with the following stretching and control elements:

• string shortage detectors
• gravitation compensators
• disk stretchers
• signal lamp
