Clipping Machines

When buying your clipping machine, look for high-quality components. To ensure a long service life and to minimise corrosion and wear, as many metal parts as possible in a Poly-clip machine are made of high-quality stainless steel or titanium. The components in the area in contact with the product are food-safe so that your product is not contaminated. Where plastic is the ideal material, we only use high-quality, durable materials. Quality makes the difference – you can be sure with us.

Long-term supplier relationships with a very high proportion from Germany contribute to quality assurance and increase delivery reliability. They also ensure delivery times and the supply of spare parts. Our suppliers are continuously monitored by the purchasing and quality departments. Supplier audits and permanent monitoring lead to the best quality and stable processes.

Certain parts require years of development and expertise that a supplier may not be able to fulfil. Quality controls are safest in your own hands. Especially for wear parts, such as punches and dies or displacement plates, we rely on in-house production.

Parts of the clip and separator area, such as punches and dies or separator plates, are subjected to a detailed, traceable inspection. So that nothing stands in the way of your fault-free production, even after wear part replacement.

Assembly steps of a machine are carried out by several employees who check on each other. The entire assembly of the machine is supported by documented test points. This ensures quality assurance at the highest level.

Each machine is subjected to a documented functional test at the end of its completion, for fault-free, the fastest possible commissioning at your production site.

With us, you get high-quality original spare parts, delivered reliably and quickly, even if your machine is already a few years older. Poly-clip System supplies you with spare parts, even many years after the model has been discontinued. You can rely on us!

And if you ever need support, we have an expert hotline and a worldwide service network on site to get your machine back into production as quickly as possible.

The choice is yours – don't just invest in a machine, invest in a Poly-clip system!

We will be happy to advise you personally on finding the right machine for your application. Or do you have any questions about other products and services? Do not hesitate to contact us.

Besides the single-clipping procedure, in which only one clip is ever applied at a time, there is the double-clipping procedure.

With the clipping system of a double-clipper, two closures are performed simultaneously, that is to say, the end of the filled packaging unit and the beginning of the next, as yet unfilled packaging unit, are closed at the same time. In this case a knife cuts through the casing (tubular bag) between the two clips and the next unit is then filled.

In order for a clip to be applied, ideally an empty space must first be created in the casing or tubular bag where the clip is to be placed. This is where the “separator” comes in.

The simplest version of this is the “normal” separator. To produce as clean a casing tail as possible, many double-clippers employ the tried and tested voiding separator.
Two pairs of separator blades apply a V-shaped notch – as with a pair of scissors – to the filled casing and constrict it. The so-called “spreading” process then commences, as the left-hand pair of separators is moved away from the stationary right-hand pair. The spreading process produces a clean casing tail of predetermined length, free of filling, around which the two clip closures are created. The (sausage-shaped) finished portion can then be separated between the closures.

Today, clipping is a natural and core component of all industrial sausage production.

And for small and medium-sized operations, too, the clipping machine has become part of the armoury of important production tools which considerably lightens the workload and saves time, as it replaces the labour-intensive tying procedure. But it is not as run-of-the-mill as it sounds. It is of course the form of a clip closure that is always demanded for a casing or tubular bag, but the requirements placed upon this closure are extremely varied.

Clip closure is subject to a range of conflicting requirements. It must, for example, close casings and tubular bags of differing thickness, sensitivity and hardness, and must do so gently, but also powerfully. Pre-tied casings with widely differing filling capacity must be closed just as securely as products which are divided into portions of precise weight. Production speeds up to 300 portions per minute are possible, depending on the filling weight, product viscosity and package calibre (diameter). In addition, there are a variety of product forms involved, such as portioned sausages (chubs), rounds, half rounds and bladders.

Additionally, the clip closure must withstand the high filling pressure, and it must be tight, but also flexible where necessary. Clip closure must be dimensionally stable even above 80 °C, since the product is sometimes subjected to further thermal treatment, as in the case of cheese which is smoked. It must be capable of closing both hot- and cold-filled products. Thus, clipping technology is more demanding than it might at first seem.

A growing number of clip types and sizes are on offer for the various casing types and products. A basic distinction is made between pre-formed reel clips (R-Clip, R-ID Clip) and U-shaped single clips (S-Clip/U-Clip). Clips on reels (spools) are the indispensable standard in industrial manufacture.

S-clips are used for special applications, for example where high product weights or very large calibres are involved, for the processing of portioned products (with pre-tying), with natural casings for traditional products and with table-top machines. The wide range of requirements made by small and medium-sized firms are also exceptionally well catered for by the multi-faceted S-clips.
