DS 21/30 EC meets all requirements of conventional warp preparation
Apr '09
The DS 21/30 EC – a new computer-controlled direct warping machine developed by KARL MAYER for the warp knitting sector.

KARL MAYER's DS machine series represents highly efficient technology for use in warp preparation for warp knitting. A well-thought-out construction and intelligent design features enable high speeds of up to 1,200 m/min to be achieved when producing sectional warp beams having identical circumferences and lengths, whilst guaranteeing accurate and reliable operation at the same time.

KARL MAYER's high-speed direct warping machines operate using optimally coordinated creel systems, feed units and synchronised braking systems. All the operating conditions, start/stop and running phases are 100% computer-controlled, and any variations in the circumference of the sectional warp beams are extremely small. The maximum variation is no more than a millimetre, even when extremely delicate yarns are being processed.

If the machine has to be braked, highly innovative synchronised braking systems stop the machine in just 0.6 seconds, and the running of the yarn sheet is fully controlled, even when the machine has been operating at high speed. These performance features can all be utilised very easily via the KAMCOS machine control system.

The Operator Interface with touchscreen facility gives a clear view of what is happening, and enables all the machine functions to be accessed easily. An Ethernet interface permits the data acquisition and Teleservice modules to be connected up. These performance features have ensured that all the models in KARL MAYER's range of direct warping machines have become real bestsellers on the market.

DS 21/30 EC
A new model in the successful DS series is the DS 21/30 EC. This new warping machine is based on a rational design concept, is relatively cheap, and is designed to produce standard articles on a price-oriented market. These features mean that it is perfectly matched to suit the requirements of KARL MAYER's TM 2 and TM 3 machines. The performance features of these two basic tricot machines, which are designed to appeal to manufacturers who are new to this sector, can be fully utilised by using them in combination with the DS 21/30 EC.

The construction of the DS 21/30 EC has been logically designed to provide practical solutions. The technology for producing the sectional warp beams enables a warping speed of up to 1,000 m/min to be achieved, and yarn tension values up to a maximum of 200 N to be processed.

The special technical features include computer-controlled band build-up, a master beam/successive beam control system, an integrated MMI operator console, an intelligent, synchronised braking system, the tried-and-tested KAMCOS control system, and facilities for connecting-up additional units. The touchscreen monitor is an easy-to-use man/machine interface and can be used to display the process parameters and input the beam data. A range of different functions can also be activated and master lists can be stored - simply by pressing buttons.
