Rollforming boost with
roll design expertise
Somass, Germany, provides a
comprehensive roll design service
to optimize rollforming and assist
manufacturers of welded tube. This
capability is aimed at those that design and
produce welded round and shaped tubes,
together with open and closed sections.
In the area of welded tubes, the company
offers design experience to assist
manufacture of products from extremely
thin-walled tubes to thick walled pipeline.
Somass can support the development of
rollforming strategies, definition of machine
layouts and also verification of rollform
tools. All delivered designs from the
company are proofed and verified by Finite
Element Analysis (FEA).
Certified according to DIN EN ISO
9001:2000, the company provides complete
documentation for all work.

The punched holes can be supplied in any
pattern and in a variety of shapes.
Taylor-Winfield rollforming lines are used
to manufacture a vast range of products
for many diverse industries including
construction, automotive, electrical, security,
both white and brown goods, industrial
storage, transport, and office furniture.
Features of Taylor-Winfield lines include
automatic entry coil loading and feed up,
multiple pre-piercing and shearing with
PLC and PC control, high speed flying
cut-offs, cassette section roll change, auto
changeover, and offline punch/welding
systems. Automatic stacking with weight,
wrap and bar coding facilities can also be
provided for finished products.
Taylor-Winfield’s tube mills operate with
precut blanks fed into the machine and
formed into tubular shapes. The two edges
are then seamed together using welding or
mechanical lockseaming.
The company can process
a wide range of diameters,
lengths and thicknesses in
round, oval, asymmetrical
and tapered tubes.
Taylor-Winfield offers two
platforms of machines. The
high precision platform
forms the blank around
a mandrel and holds the
blank in place while a
rollforming carriage/weld
head traverses across the
top and forms a lockseam/
weld.
The company’s highly
flexible platform for
lockseaming forms the
blank in a rolling unit,
feeds the rolled blank
into a pulldown press and
feeds the pre-edged part
into seaming rolls. With
automatic changeover,
this machine is capable
of running alternating
diameter parts.
The highly flexible platform
for welding forms the blank
in a rolling unit and feeds
the blank onto a z-bar. In
resistance seam welding,
the rolled blank is then
Taylor-Winfield Corporation, USA,
specialises in the automation of applications
involving material joining, forming and
assembly, coil joining and induction heating.
The company offers a wide range of
equipment including coil joining equipment,
automated assembly lines, metal forming
equipment, and work handling systems.
Rollforming lines are used to convert
incoming flat strip into a variety of shapes
and sections and in a wide range of
thicknesses, widths, lengths and materials.
The required shape is obtained by passing
the incoming material through a series
of driven profiled rolls. The rolls are set in
pairs (upper and lower) and gradually form
the material until the final shape/cross
section is obtained.
Prior to the actual forming operations,
Taylor-Winfield lines can also punch holes,
notch, emboss and knurl the incoming strip
as necessary for assembly/fixing purposes.

 Tubes can be produced on Taylor-Winfield tube
mills, which take-in precut blanks that have their
two edges seamed together using welding or
