DS 21/30 EC practical warper makes in-roads in world markets

1st April 2009, Obertshausen – Karl Mayer’s new DS 21/30 EC direct warping machine has been used successfully in the Asian market since August 2008, and has been available on the world market since January of this year.

Karl Mayer’s DS machine series has represented highly efficient technology for use in warp preparation for warp knitting for some years. Sound construction principles and intelligent design features enable high speeds of up to 1,200 m/min to be achieved when producing sectional warp beams with identical circumferences and lengths, whilst guaranteeing accurate and reliable operation.

The company’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 completely computer-controlled, and variations in the circumference of the sectional warp beams are kept to a minimum.

According to Karl Mayer, the maximum variation is no more than one 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, Karl Mayer says. The Operator Interface with touch screen 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 and it is these features which have helped Karl Mayer’s range of direct warping machines to become bestsellers in the market.

A new model in the successful DS series is the DS 21/30 EC. Karl Mayer says, this new warping machine is based on a rationalized design concept, is relatively cheap, and is designed to produce standard articles in a price-oriented market. The company emphasises that 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 company adds.

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 touch screen 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 by simply by pressing buttons.

Karl Mayer claims that the DS 21/30 EC is a rational, robust production machine, which meets all the requirements of conventional warp preparation and is another contribution from Karl Mayer for producing standard products economically. The new DS 21/30 EC model in the DS range has been used successfully in the Asian market since August 2008, and has been available on the world market since January of this year.
