The customer benefits from high production reliability, also for small batch sizes. Motor drives which are mainly employed ensure a high availability. Cycle speeds of up to 22 cycles/min can be achieved in combination with cam-controlled table movements in the forming and sealing station.
Equipment kits and additional solutions offered by ILLIG meet different production requirements and performance levels, from standard applications through to forming with sterile pressure air. The punching station is suitable for different punching systems.
After unreeling the material reaches the heating station. During several cycles the contact heating plates heat up the material to the optimum forming temperature. It is only the material surface which is heated by format-milled heating plates. Unheated bridges minimize material shrinkage in longitudinal and cross direction. Upon machine stop the heating station automatically opens. Cups are formed with pressure air, forming is supported by pneumatically driven pre-stretching plugs.

Sealing station with lid material feed
The parameters required for sealing, such as pressures and temperatures, can be individually adjusted with respect to materials used. Precision-processing of printed lid material is ensured due to the print mark control unit. Slight thickness variations of the material are automatically offset during sealing. This way cups are always precision-sealed. Upon machine stop the sealing electrode automatically lifts, thus overheating of material and product is prevented.
High packing quality and minimum waste
The ILLIG multiple gripper transport system provides for maximum safety during material transport through the machine. Very narrow lateral material edges of only approx. 6 mm, depending on the material processed, make sure the machine’s format area can be optimally used without any additional material loss.
Automatic positioning of sealing and punching station
Narrow edges can be achieved on steep packs thanks to the automatic positioning of these units as well as very safe operation. The formed cups are detected by light barriers across the feed direction and in case of mismatch the position of the sealing and/or punching station is automatically corrected (optional extra). This way even sealing and punching edges are achieved even after a machine stop. Malfunction due to material shrinkage and pack mismatch is avoided.
ILLIG control technology
The ILLIG standard ensures smooth production sequencing as well as a consistently high quality level. Besides electronic process control suitable for FFS machines, we offer interlinkage of individual components to form a complete machine line. The automatic start included in the basic equipment ensures a smooth, waste-free start after every stop.
The packs are punched out of the web. High punching forces can be applied due to the four-pillar guiding element. Indexing tolerances are offset by the automatic positioning of the punch press (optional extra). This way punching mismatch is prevented. The skeletal is reduced by a cross cutter and discharged from the back of the machine by a chute.
