With this machine it is possible to carry out both expansion and beading.
The female profile is processed by an internal 8-sector expasion head and an external roller, while the male one is typically processed by a couple of rollers – one internal and one external.
It’s TTE’s solution to perfom the so called “hemming” profile: it consists of a cut-resistant processing at the pipe end, where a reverse flanging is carried out. The machine is composed of an internal mandrel, which varies at each diameter change, and a unique external roller, which performs the “hemming” profiling involving an internal contrast roller.
This machine perfoms pipe shrinking/reduction by means of 8 internal sectors and 8 external closing sectors.
With this machine it is also possible to prepare special sections for external gasket seats.
It is a profiling machine made of 2 external rollers with automatic setup and 1 internal roller, enabling 2 different processes without having to do any format change.
Therefore with this machine there is no need to change toolings as diameters change.
In addition it can be designed in both vertical and horizontal versions.
