The expectations of your customers in respect of quality slide-out rails are high: high load bearing capacity, small installation space, minimum noise, long service life are just a few of the requirements. Their product designers fulfil these wishes with complex profile cross-sections, complex punching or embossing, minimum roughness of the running surfaces and tolerances which elsewhere in the sheet processing sector would be classified as unachievable: Many products of the market leaders are produced on our roll forming systems.

With our roll forming systems for slide-out rails, you will not only benefit from high productivity: first and foremost our roll forming machines are characterised by their short pay-back times. Our further development of roll forming technology reduces your material consumption by up to 6 per cent and ensures a correspondingly higher production volume.

Within an overall concept, you will also receive the appropriate strip-feeding system from us: It is used for the continuous supply of the roll forming system with the raw material, the flat strip. Flat strip systems make an important contribution to the productivity of the overall system and the quality of the parts. Highly automated strip systems perform a complete coil change in 3 minutes, including welding of the strip ends. Precision-alignment systems and a low-stress strip feed into the downstream punching or roll forming machines provide the necessary conditions for the production of precision components with the narrowest of tolerances. Dependent on the nature of the requirements, the more cost-efficient standard system can also be used.

The core of a system for the production of slide-out rails is our roll forming machine with the roll forming tool. Process-sure tolerances down to a few thousandths of an inch can only be achieved if there is perfect interaction between the forming technology and the machine. Simultaneously, high production rates of up to 120 parts per minute are achieved. Of particular importance here is the Start-Stop® operation introduced by us. Here the roll forming machine operates like a highly dynamic precision roller feed, feeding the completed parts with high positional accuracy to the downstream press and punching tools. A further advantage are the low tool costs, especially when producing length variants. Also very important is the low material consumption: In order to achieve a very high level of process reliability, Dreistern utilises skin-passing as a newly developed technology. The skin-pass mill reduces the strip thickness to a very narrow tolerance. Another effect that makes this investment absolutely necessary is the reduction in the amount of material used, as the reduced strip thickness is reflected one-to-one in the strip length.

Dependent on the requirement, we will put into practice roll forming concepts for ensuring maximum production performance while for extreme requirements the emphasis is on flexibility. This means production performance of up to 120 parts per minute and changeover times of a few minutes. Thus, when producing length variants, the individual tools can be moved automatically and precisely into the new position. Special control software can reduce the amount of scrap during length changes and in many cases limit it to zero. This helps you to save material costs. Not every rail production requires a high performance system: for reduced requirements focussed on the production performance or changeover times, we can supply you with particularly economic standard systems. Irrespective of whether they are high performance or standard systems, all of our roll forming systems operate with notable quietness thanks to effective sound insulation. The sound insulation is designed so that access to the system when operating or during changeovers is not significantly impaired.
