At India ITME in December 2022 in Noida/India, the latest generation of Groz-Beckert's fully automatic drawing-in machine – the WarpMasterPlus – was presented live on site for the first time in Asia. In addition, Groz-Beckert presented its knotting machine KnotMaster.
With the new WarpMasterPlus, Groz-Beckert KG, Albstadt/Germany, relied on the proven drawing-in concept, where the drawing-in takes place through a single yarn package technology. The system has been newly constructed from the scratch. The latest technologies were consistently used to bring a machine to the market that is already equipped today for future requirements with regard to increased automation in the course of Industry 4.0.
Maximum flexibility with minimum setup time were further focal points in the development, as well as maximized machine efficiency and simultaneously reduce the loading and unloading time. For this purpose, the number of cycles has been increased and sophisticated functions such as pre-setting drop wire magazines and CNC axes for adjusting the heald length have been added. Conversion times can be reduced to a minimum with different accessories.
The WarpMasterPlus, along with other machines from the Groz-Beckert’s Weaving Division portfolio are also available for training, tests and demonstrations at the recently inaugurated showroom in Ichalkaranji in Kolhapur District of Maharashtra State/India, such as the KnotMaster. Sophisticated technology and simple operation for a wide range of applications are considered the big advantages of the KnotMaster series. Customers benefit from rapid warp changes and reduced processing times for a more efficient and cost-effective weaving preparation. This machine impresses with its high-performance achieving up to 600 knots per minute.
Intelligent technical features of the KnotMaster increase both process reliability and reproducibility. The yarn clamps with a separate clamping system for example, allow the clamping of different yarn thicknesses. Differences in thickness are automatically compensated. Thanks to the automatic repeater, the KnotMaster ensures highest process reliability. In case the separation unit cannot select a yarn on the first attempt, the control repeats the attempt by a predefined number of times. This happens at the full speed of the tying process.
