Bluhm Systeme GmbH has been working closely with igus for five years now. This was prompted by a customer request for a labeller with flexible format adjustment. What was needed was a device that can attach labels of various sizes and whose setting width can be flexibly adapted to the product to be la-belled. In search of a suitable solution for the adjustment unit, the manufacturer of labelling systems came across igus. "First and foremost, three things were decisive for us: price, reliability and the fulfilment of technical requirements," recalls Andreas Koch, Sales Director at Bluhm. The Tamper Evident is a com-pact labeller used in the pharmaceutical, food and cosmetics industries to ap-ply various sealing labels to products of different sizes.

Initially, Bluhm employees assembled the igus components for the adjustment unit themselves and installed them on the Tamper Evident. However, the as-sembly turned out to be very time consuming. "We wanted to make this pro-cess more effective and speed up the installation of the adjustment unit in the Tamper Evident. So we got igus back on board," Koch explains. To simplify the process for Bluhm and shorten assembly times, igus offered a ready-to-install format adjustment unit. The production of individual labelling systems is not uncommon for Bluhm. "igus offers individual solutions. Special product requests are very appealing to us, because it makes us even more flexible. This allows us to respond even better to the wishes of our customers," says Koch.

The drylin linear guides give the Tamper Evident, with its adjustment unit, max-imum flexibility in the adjustment of the labeller. They are also resistant to dust and dirt, making the labeller also suitable for harsh environments. In addition, the linear guides operate without additional lubrication, since their sliding ele-ments contain incorporated lubricants. "This not only saves our customers maintenance time, but also costs for maintenance and lubricants," confirms Koch.

The long service life of the drylin linear guides enables Bluhm Systeme GmbH to supply its customers with a top quality product. The repeatability, precision and speed of the drylin components reduced the batch change time of the Tamper Evident. Koch is convinced that these specifications pay off for his customers: "This labeller can attach 500 sealing labels per minute. It pays off every second that you can save in adjustment." That's why the complete au-tomation of label changes and format settings is a topic that is consistently pur-sued at Bluhm. It saves additional time and reduces sources of error. "We are already planning new projects with igus for the future, as the demand for our machines is increasing," says Koch.
