New fastening system MAGNOTOP for flat clothings

For more than 100 years flats were made of cast iron. In 1991, Truetzschler introduced the higher-precision aluminium profiled bars. Meanwhile, all well-known card manufacturers have adopted this technology.
At ITMA Munich, Truetzschler exhibited a new development stage, the MAGNOTOP system. This innovation is the result of intensive development cooperation between card specialist Truetzschler and clothing specialist Truetzschler Card Clothing.
Up to now, the flats made of cast-iron as well as of aluminium were attached with so-called clips. These clips are made of sheet steel, which is shaped by a special machine for fastening.
This process requires not only the special machine, but also trained personnel for its operation. Another disadvantage of the conventional system is a certain inaccuracy that is caused by the clipping process.
This inaccuracy must be compensated by subsequent grinding. Removal of the worn flat clothings requires yet another special machine.
With MAGNOTOP, all this is history. MAGNOTOP uses magnetic forces to fasten the flat clothing onto the flat. For this purpose, a thin sheet plate is glued to the back of the flat clothing.
A magnetic strip is attached to the flat. The adhesive technology offers a very important advantage. The thin adhesive layers function as tolerance compensation.
Small tolerances in flat clothing strips or in the flat are eliminated. Thus, MAGNOTOP flat systems can be set with higher accuracy. This improves the carding quality noticeably.
Naturally, this system uses no average magnets. Truetzschler applies super-strong neodymium magnets. The magnet strip of a flat is designed to hold 100 kg. The clothing strip only weighs a fraction of that. The carding forces on the flat are also significantly lower.
Despite these high magnetic forces, replacement does not require much effort. The clothing strip is raised at the end and then simply peeled off. The process calls to mind the peeling of a banana.
In addition to eliminating the expensive machines for flat fastening, there is also no longer a need for the entire flats workshop.
Clothing replacement is done directly at the card. After the replacement, the old clothing strips are not destroyed. Thus, tests with new clothing types can be performed without much expenditure.
