Designs
Heat Sealed
The optimum design for bellows is the heat-sealed version. The cover material and guide frames made from PVC are permanently joined. The connection of the bellows material and the guide frames ensures maximum loading capacity and absolute tightness against liquids such as cooling or grinding fluids. For special requirements, e.g. resistance to temperatures of up to 752 °F (400 °C), stitched bellows can be used. Heat-sealed bellows can be manufactured in widths of up to 3 meters.
Round Bellows
We make bellows with round, oval or rectangular (with rounded off corners) cross-sections using a special sewing method. Support rings will be used to meet special requirements and applications. Due to their robust design, these bellows have a long and reliable service life, even under extreme mechanical and dynamic strain. The temperature resistance of these bellows can be increased to approx. 752 °F (400 °C) when using an aluminized fabric.
Glued Bellows - Can Be Adapted to Any Shape
These bellows consist of up to three foils glued together in sandwich construction. Special shapes such as polygonal bellows, bellows with negative folding in the opposite direction, or bellows with small fold widths, can be easily constructed. Due to the special gluing of materials, these bellows provide maximum protection, even against liquids.
Fixed Steel Lamellas – A Solid Solution
Hennig has developed lamella bellows to meet particularly high requirements. This type fills the gap between telescopic steel covers and conventional bellows. The lamella bellows are based on our heat-sealed or stitched designs. Each fold has its own guide frame which is sealed to the cover material. Lamellas made from stainless steel protect the bellows against red hot, sharp-edged swarf, or mechanical strain.
Hinged Steel Lamellas – If Space is Limited
Do you need vertically mounted bellows? Without lamella overhang? In such a case our bellows with hinged lamellas are the perfect solution for you. Each lamella is flexibly fixed to the PVC frame. Therefore, the lamellas can lie down flat on the machine enclosure at the bottom.
The Perfect Combination – 3-Sided Lamellas
These folded bellows feature lamellas on three sides combine the advantages of telescopic steel covers with folded bellows. Due to this combination of folded bellows and telescopic steel cover, the bellows are protected on each side, against hot, sharp chips or mechanical strain. Thanks to an ideal ratio between the extended and the compressed length, and compact dimensions because lamella has no overhang, this type of bellows is perfectly suited to limited space applications.
