Industrial multi-needle quilting machines add a wide range of stitched patterns to mattress covers. Up to now, the stumbling block to quick pattern changes has been the need to manually adapt the needle configuration. A new quilting system from Emil Stutznäcker facilitates customised, program-controlled selection of individual sewing positions from a bank of sewing units. A cylinder/valve combination developed by Festo optimises the assembly, changeover and upgrading of systems.
A hundred needles sew patterns in the soft fabric in white thread at breathtaking speed. What sounds like the buzzing of a swarm of bees soon turns into something on which people spend around one third of their lives: a mattress, or to be more precise, a mattress cover.
These days, a mattress is more than simply something to sleep on. The quality concealed on the inside should also be visible on the outside – in softly curved lines, elegant diamond shapes, perfect circles and an almost infinite number of freehand patterns. Since millions of people want to sleep as comfortably as possible, the production of mattress covers depends on high speed and increasingly also on a high degree of flexible pattern design. Emil Stutznäcker GmbH & Co. KG uses new cylinder/valve combinations with ASI technology from Festo in their latest multi-needle quilting machines in order to be able to quickly switch from one pattern to the next.
The new cylinder/valve combination with ASI bus technology and integrated AND gate enables fast, fully automated changeover of the needle configuration.
