Instead of using mechanical pattern discs, the high-performance, digital generation tricot machine HKS 3-M ON from Karl Mayer works with electronic pattern data obtained directly from the KM.ON cloud. This allows it to offer extremely short and flexible design changes, minimal down-time, and operation without the previous expense of ordering pattern discs, having them delivered, and changing and storing them.  
The Spring Motion Assistant is an automatic return device that makes changing guide bars much easier. Together with the push rod, the spring motion forms a system that transmits the pattern-specific movement impulse from the electronic pattern drive to the guide bar. The system was optimized to work with the new ON gear in the HKS 3-M ON tricot machine of the Karl Mayer Group, Obertshausen/Germany, and the developers also took this opportunity to improve it in terms of ease of use.
When it is time to change the guide bar, the operator is supported effectively by the HKS 3-M ON. There is a special function on the touchscreen that guides them through the partially automated process step by step. Once the spring motion and push rod are back in their original places with the newly threaded guide bar, the spring motion is set to the correct position and tensioned automatically. The machine lighting visually informs the operator that the function has been completed and production can continue.
The Spring Motion Assistant is convenient, safe and requires less effort from personnel than the previous system. Furthermore, the patented solution does not require any tools. The innovation now comes as standard on the HKS 3-M ON.
