Obertshausen - Warp knitting machine builder Karl Mayer has launched its widest ever tricot machine. Part of the renowned HKS machine series, the HKS 3-M is now available in a width of 280 ins.
Previously available in widths of 186 ins and 218 ins, Karl Mayer says that the new model, which is the widest available on the global market, will deliver both increased productivity and flexibility.
Like all the HKS three-bar machines, this new machine targets a wide variety of end-uses, from car interiors, furniture and sportswear, to coating/backing substrates and advertising media.
Fabrics processed with different widths can now be produced on one machine instead of two, which used to be the case. The simultaneous production of webs can also be increased by a factor of one, i.e. two webs can be produced on a 186 ins-wide machine compared to three webs on a 280 ins-wide machine, while three webs can be produced on a 218 ins-wide machine as opposed to four on the new machine.
The finished fabric is wound using standard batching unit no. 6 when using the normal-width, high-speed machines, whereas the new batching unit no. 51A is used with the new machine. Batching unit no. 51A winds the fabric on friction rollers, which are driven by the fabric take-up unit.
As well as its new features, the HKS 3-M also offers all the usual features. For example, this high-speed tricot machine operates with a 3 x 32 ins beam mounting arrangement as standard. A mounting configuration with a diameter of 40 ins for beam position GB 1, and 32 ins each for beam positions GB 2 and GB 3, is available as an option. Just like the machines with a smaller working width, the HKS 3-M, 280 ins, is available in the gauges of E 28 and E 32.
It can be equipped with the new KAMCOS 2 efficient computer platform, the LEO Low Energy Option for energy-efficient running, and a camera monitoring system above or below the web. A faceplate under the textile web for monitoring transparent fabrics is also available as an option. The knitting motions and elements are the same as on the existing machines.
"This machine delivers the dependable quality typical of all Karl Mayer’s machines," the company says, adding how it can be supervised easily and operates steadily and reliably with low maintenance requirements. "It is also extremely efficient with the HKS 3-M, 280 ins, operating at a maximum speed of 2,200 min-1. This extra-wide machine has just been launched onto the market, but a number of modifications are already on the agenda. The developers and engineers at Karl Mayer are currently working on a three-bar, high-speed tricot machine with an intermediate width of 238 ins - with the possibility of extending this by 10 ins.
