Special Design Features
With today's high-speed machines, heavy demands are placed on bellows. Hennig customers can choose between various design solutions to meet those demands. With the use of the following design features, service life can be greatly increased.
Scissors are used for high traversing speeds. This allows an even extension of all elements; across the whole extension length. As a result, the folds are less strained and the durability of the bellows is prolonged.
Rollers are used in large and heavy bellows with extension limits. They minimize friction and ensure excellent running properties.
The advantage of half-scissors is that the individual elements can be extended successively depending on the necessary extension length. Since the folds are not loaded up to the theoretically possible extension limit, the durability is also longer.
Hennig bellows consist of a bellows cover, guide and end frames. Bellows with large extension lengths are composed of various elements which are connected by intermediate frames. A wide variety of material for frames and bellows are available, allowing us to meet nearly all of our requirements.
Intermediate Steel Frames
Intermediate steel frames are used to connect the various elements, especially when extension limit systems are required. The intermediate frames are fastened to the bellows with a clamping rail. The intermediate frames can be guided by either plastic or brass rollers or gliders.
The guide frames provide the bellows with the necessary stability and enable a precise operation, even at high speeds. They are made from PVC and are directly attached to the cover. The shape of the frames is adapted by Hennig to the design required.
End frames, made from steel or aluminium, connect the bellows with the machine. Hennig offers various fastening solutions for the adaptation to different bellows and machine interfaces.
