Convergence of machines for stone and glass

The arrival of industrial synthetic materials on the stone market has surprising consequences on the machinery market. In fact, we see appearing from certain suppliers who are both on the glass and stone market on the stone machinery market, machines that were once exclusively used on the glass market.


Mainly for two reasons.


1 / These new materials are calibrated in thickness.

So we see machines appearing for polishing the edge (Bavelloni, Intermac, Bovone) similar to those used for glass (rectilinear, double edger).


The gain is much better productivity for running in and polishing the edge.


2 / Some materials are based on glass


We are witnessing the arrival of cutting systems from glass much more productive and easy to use (cutting tables, at Bavelloni, Intermac ...)

Suctions frames and pliers

This lifting and moving system is done with a vacuum pomp connected to several suction cups with safety devices inside a steel structure. It allows to lift, to move and to overbalance glass sheets.

The number and diameter for the suction cups are in connection with the glass dimensions and weight.

For the glazier where the maximum weight to move is generally under 400 Kg a suction frame with 4 suction cups is the more popular.


The main data

-The maximum weight which is going to decide about the suction number but also for the glass minimum dimensions.

-The rotation

It can be

Manual with stop every 90° when the weight to lift is not too much important.


-The overbalancing

Generally motorized but the small weight glass


-The vacuum

With electric pomp with double security network.


Suction frame from RBB ( you can see the 2 motors for rotation and overbalancing)

Main options for suctions frame

-Remote control

-Vacuum adjustment with glass thickness

-Frame with double section cup for double glazing

-Extensible arms

-Telescopic structure

-Pneumatic vacuum, rotation and overbalancing

-Double vacuum electric pomp with 4 security networks



The manual machines have from 1 to 10 suckers or more and can lift up to one ton.

The motorized machines have from 4 up to 15 suckers and can lift up to 1.5 ton.



Mechanical device to lift and move glass sheets from 3 mm up to 25 mm thicknesses and up to one ton weight.


These machines can be used to move other materials.
