The company Friedrich Maschinen- und Werkzeugbau GmbH, or, more concisely, FMW, was founded in the year 1948 at Remshalden near Stuttgart. The family-run company develops and produces riveting machines, special-purpose machines and electrically operated presses for the automotive, fittings and electrical industries.
The deformation does not entail a rotational movement. Due to a high axial force, the part hole is well filled and a large bearing pressure is generated also at depth.
The riveting die is driven by a circular movement and thus rotates with a constant setting angle. The churned material deformation caused by this process requires excellent parts fixing.
The riveting die depicts a hypocycloid movement. It permanently alternates between vertical position and maximum deflection angle. The resulting point contact compresses the riveting material in its depth and forms it into a stable snap head from the inside out.

Friedrich can offer a wide range of accessories for all riveting machines. In addition to the standard products also customised components can be made available. At our customers’ request we shall be pleased to implement any workplace layout and any level of automation.
Depending on the application, different roll-forming head shapes with fixed or adjustable rolls are used. Roll-forming heads are available with one roll only or with several rolls, although it has to be said that mostly heads with 3 rolls are used. Those pressure rolls may be arranged vertically and horizontally as well as at a determined angle to the vertical axis.
Roll-forming diameters : ø7 to ø120 mm
Materials suited for roll-forming: steel, stainless steel, aluminium, pressure die cast
(Al, Zn or brass alloys)
Roll-forming head and roll-forming unit types and sizes:
2 standard sizes exist:
VR2xx with NE2xx (hydraulic feed up to 12 kN, max. stroke 80 mm)
VR5xx with NE5xx (hydraulic feed up to 40 kN, max. stroke 72 mm)
Quality Assurance:
The Friedrich roll-forming units can, of course, be combined with electronic quality assurance systems. To this effect various controls and programmes are available which are based on pressure versus displacement measurements and matched to the special conditions of roll-formed unions.
Roll-forming head with horizontally-arranged rolls
Scope of application Ø14-35 mm
Roll-forming head with vertically-arranged rolls
Scope of application Ø 30-110 mm
