Doubleclipper SK4-90

The SK4-90 is a manually-operated, semi-automatic pneumatic double-clipper. The SK4-90 is able to process clip series H-3214. This series is suitable for sealing larger calibers natural, artificial and plastic casings (tubular film) using an aluminium clip.


The SK-4-90 is a manual double-clip machine which is operated using compressed air. The clipmachine can be mechanically and electrically connected to a filling machine. The filling tube is revealed by opening the top section, after which the new casing can be placed. The casing is passed through a casing brake, which helps to realise the required product tension. The top section is then closed again and the first clips can be sealed by pushing the gatherer handle downwards. The next portion will then be automatically supplied by the filling machine, once the gatherer handle returns to the top position.

The closing force of the clip - clip pressure - can be adjusted manually. The standard pneumatic blade can be activated if necessary to create individual sausages or chain-based portions. The operator can manually insert a loop which will allow sausages to be hung up. This can also be done automatically using a loop device. The machine can be fitted with an automatic cord-feed unit for the production of ring-shaped sausages. The optional spool-clip system helps to ensure continuous production.

Advantages of the SK4-90:

- Based on compressed air

- Casing brake and filling tube automatically move downwards during the clipping process, so the clip will

  be in the middle of the product and extra pressure will not be placed on the casing
- PLC controls
- Can be connected to any filling machine
- Long life-span due to the use of high quality materials
- Easy to clean
- Minimum maintenance required
