OUR
OF EXCELLENCE
MEMBERAs metal removal rates on machine tools continue to increase, the removal of swarf becomes a significant consideration. To meet these increasing demands we continue to be at the forefront of swarf removal by offering a comprehensive range of swarf conveyors to suit most applications.
Machine design should be such that all swarf and coolant flow can be easily directed without obstruction into the swarf conveyor and sufficient space be allowed for a conveyor case that is compatible with the machine performance (recommended case sizes are listed for various types).
Our rollaway covers are a valid alternative for bellow type applications. Whenever you have limitations regarding space, you should think of a roller cover or apron type protection. We have developed the roller cover line to a remarkable product with many features and options. In the last twenty years we have gained experience by manufacturing over 5,000 roller covers and aprons.
Today we can offer a standard product range with:
This gives you a choice of almost 6,000 combinations. Besides we offer you customized special solutions for your individual application. Our products are made of high-quality materials. Through our own quality management system which is working according to the rules and guidelines of ISO 9001 we can guarantee high quality products and an outstanding performance. By using special testing equipment and closely monitoring the output of our production, we can deliver permanent and reliable quality.
The durability and product life time is directly depending on:
If all these factors are considered and within a normal range our products can reach travel speeds of 40 meters / 1,500 Inch per minute. In every case our engineers can give you detailed information on the technical performance data of the inquired roller cover.
If you are looking for a high-quality, long-lasting, efficient, well-designed and perfectly performing roller cover or apron protection, get the product from one of the most experienced and recognized sources in the business – Us.

Our rollaway covers are produced to meet the requirements of the machine tool industry (and many other industries), offer protection against machine swarf, dust and cutting fluids and provide additional working safety.
They are designed for horizontal and vertical applications (see operating positions on inquiry sheet). Excellent extension to compression ratios offer little resistance to machine capacity, and their clean lines and smart finish will compliment the appearance of your machine tools.
Our rollaway covers can be manufactured in three different basic technical systems depending on the application and the technical requirements. We will design the product according to your specifications. For standard applications we mostly use high-quality torsion springs which guarantee an excellent performance at reasonable costs. For heavy duty applications you cannot use torsion springs as of their limited forces. We have developed a more advanced solution – the special. These provide the additional power and strength. Another innovative idea from us giving you the best you deserve.
When using stainless steel band the band, width can be up to 1,000 mm / 40 Inches. In the case your application requires a fabric band, the width can go up to 6,000 mm / 240 Inches.

The demand for roller covers with flexible aprons was initiated to protect machines against hot or heavy chip/swarfs. You should give your machine this additional shield protection. The standard roller cover with fabric band cannot be recommended for these applications. The roller covers with flexible aprons don't offer you walk-on capability.
The roller covers with flexible aprons are available in different designs, materials and sizes. If you have limited space we recommend an apron type with curved aluminum links which are riveted to a synthetic fabric with two sided PVC / polyurethane coating or heat resistant aluminum coating. Basically you can also use regular flat brass, steel or aluminum links.
We can even provide you with an all-metal band consisting of aluminum segments. We offer a hollow type and a solid construction. The aluminum links are interlocked with polyurethane hinges providing effective protection against coolants. The low weight of approximately 8 kg / 17.6 lbs per sqm and the small size makes the product perfect for today's machines.
Basic operating situations available
Our flexible aprons are an easy and inexpensive solution for special applications where only a front protection is required. All products are customized and can be delivered within a short period.
The apron usually consists of a basic fabric structure with riveted link material. The link material can be brass, (stainless) steel or aluminum in flat or curved shapes. The heavy duty type aprons consist of a special hollow aluminum construction. You can choose either a metal to metal connection or a design where the aluminum links are connected with polyurethane hinges offering a coolant resistance.
For easy installation we offer you basically three alternatives: as a simple hanging shield, hanging over a deflection roller or in connection with a roller cover (even with an enclosure). For the deflection roller you can use the same technical details as for the mounting brackets for roller covers (see previous section).
Our roller covers with enclosures offer a protection for the roller itself against the working environment, require a minimum of space and can be manufactured customized in different designs.
The enclosure itself can be produced of stainless steel, aluminum, color anodizing or other surface treatments. The standard housing sizes are available from 40 by 40 mm (1.57" × 1.57 Inch) to 120 by 120 mm (4.72" × 4.72 Inch). The enclosure width is not limited. When using stainless steel band the band width can be up to 1,000 mm / 40 Inches. In the case your application requires a fabric band, the width can go up to 6,000 mm / 240 Inches.
Our roller covers with enclosure are designed for use in horizontal and vertical positions. Please give us detailed information about the operating position. All roller covers with enclosure are ready to fit into your application. They are factory preadjusted to the necessary forces. Through our special inquiry sheets we will guide you through the design process and make sure that all important information have been considered and included.
