2.8 Maximum speed (by capstan device) – 50 m/min.
2.9 Type of bobbins:
- Pay-off:
a) bobbin with dieter of 400 mm (Appendix 1) or 500 (Appendix 2);
b) for the central core, metal drums according to DIN 46391/46395 1250-1600 mm;
- Take-up:  bobbins DIN 46391/46395 with diameter of 1250-1600 mm.

3.1 The design of the machine must ensure:
