Aluminum and carbon fiber in perfect union –
fulfill the highest demands with the new high-performance heald frame ALtop® HYBRID

"Hybrid" refers to a combination or a cross between two different things. With its new high-performance heald frame, Groz-Beckert shows how to create synergies without any compromises. The ALtop® HYBRID is based on proven and innovative lightweight aluminum profiles which have also been carbon-fiber-reinforced. As a result, the uniquely high bending resistance of the frame staves makes the ALtop® HYBRID an ideal addition to the ALtop® family. The ALtop® HYBRID premiered at the ITMA ASIA 2012.

The carbon-fiber-reinforced profile

Innovative design with aluminum profile and high-performance carbon fibers

The ultra-lightweight frame staves on the ALtop® HYBRID are ideally suited to the dynamic loads of modern high-speed weaving machines – and this is an especially critical factor in applications with positively-controlled heald frame movements.


Tried and tested corner connection

The corner connection contains no moving components. This guarantees a firm screw connection and simple, precise lateral support positioning, ensuring that the frame will withstand extreme loads but at the same time facilitating simple, reliable warp preparation


It's all in the material


The selected materials used for the ALtop® HYBRID are extremely lightweight but still durable and resistant to bending – with no intermediate support. This increases the service life and durability of the heald frames and weaving machines. The low weight of the ALtop® HYBRID also facilitates handling in daily operation.

Varied range of application on air-jet, projectile and rapier weaving machines

The new heald frame has a highly diverse range of applications. Weaving mills now have all kinds of possible options, also because Groz-Beckert offers the ALtop® HYBRID in all the standard nominal widths.

For weaving machines with two drive points, double carbon-fiber-reinforced staves are used both for the upper and the lower frame stave.

For weaving machines with three or more drive points, a double carbon-fiber-reinforced frame stave is used above. Below, a geometrically adapted light metal frame stave is used.

A great deal to offer
