HEMA. Tailor made Protective Systems.
Machine tools and production systems
Precision, process reliability, and productivity thanks to robust
04 system solutions and components
HEMA components protect machines and operators effectively
and efficiently against flying chips, cooling lubricants, and
injury from moving parts.
We raise the service life and availability of the machine and
08 keep the operator safe from harm.
Laser cutting machines
18 Optical waveguides or deflecting mirrors guide laser beams
to the machining optics. The beam path is protected with
special bellows particularly on machines with moving optics.
26
Machine tools for nonmetals
32 Special materials are matched to the requirements of non-
metal machining types.
These can be for instance slats for the optimal protection
against sharp chips or particularly smooth surfaces of teflon
material for the enhanced runoff of powdery removal.
38
46 Testing and measuring systems
In the test room the task is to find the µ under climate
controlled conditions. A low noise and low friction process
coupled with a low compressing counterpressure are only
two of the requirements for our bellows and shutter systems.
58 Perfect systems, the optimal surface feel, and tight tolerance
designs are the specifications for our production and quality
assurance standards.
Robotics, automation, and handling
We utilise high strength materials with superior flex fatigue
properties that safeguard fast, precise traverses on linear
guide rails and the greatest possible flexibility for special
designs.
Here we can provide the corresponding supplements to our
rail and rod clamping systems.

Innovation never ends.
For more than forty years we have been manufacturing protective systems for the world’s machinery
building sectors.. Our first products were bellows and coil springs that we produced in Seligenstadt,
which is still our head office today. Through consistent further development our range of bellows as 05
protective covers for guides evolved into the SAMURAI product series with slat reinforced bellows and
aprons and complete rear wall systems. Our spiral springs were joined by other product ranges like
telescopic steel covers, shutter covers, segmented aprons, machine safety screens, and Visiport spin
windows that today supplement our range of offers.
Our second field of competence concentrates on pneumatic clamping and braking systems for linear 08
and rotary clamping. You can view extensive information on these products in an additional catalogue Research and development
we have put together for you.
This product diversity is possible only with extensive research and development as well as intensive
detailed work. In close collaboration e.g. with the Production Management, Technology, and Machine CERTIFICATE The Certification Body
of TÜV SÜD Management Service GmbH
certifies that

ELASTIC Bellows
ELASTIC Bellows are commonly used for protecting machines
and devices against debris and chips. They are also used in
many variations for safety at work. 02
The experience resulting from the production of many
thousands of ELASTIC Bellows and their use in working
applications has been converted directly into product improve-
ments, new developments, and enhanced product lifetime.

ELASTIC Bellows
ELASTIC bellows are available in the following versions
depending on how their frames are permanently joined to the

32 yellow or white materials for medical applications are
available.
The material is selected from a large range of products to
match the intended use of the ELASTIC Bellows.
Also self extinguishing heat resisting materials under the
38 UL 94 standard are available.
Design of ELASTIC Bellows
The essential component of the ELASTIC Bellows is a stabili-
sing PVC frame inside every fold that lends the ELASTIC
46 Bellows high dimensional stability. Reversion to the original
shape is therefore assured after direct impacts.
Beside PVC frames PP and Polyamide can be offered as an
alternative material for the support frames.

The sewn version consists primarily of high temperature

Mounting
ELASTIC Bellows can be easily mounted on machines and
devices with components such as:
frames of metal or synthetic material attached to both
ends and designed to customer specifications
Velcro tape, easy and fast, maintenance friendly

18 A further benefit of these bellows comes in the form of their
segmented design. Damaged parts of the LAMINAT Bellows
can be easily replaced, reducing significantly the costs for
maintenance.

Special Bellows
Rubber Disk Bellows
Rubber disk bellows are of the highest quality and visually
the most attractive protective covers for pistons and spind-
02 les. They are completely leak proof. Since each rubber disk
lies flat on the other, excellent compression dimensions are
achieved.
The production of rubber parts depends directly upon the
control and monitoring of the production processes. Each
08 process step, from mixing up to rolling out the material,
from punching the disks up to the vulcanization process, is
performed under the most accurate observation and attenti-
on. Stringent quality criteria leads to high process reliabili-
ty. After vulcanizing, the rubber disk bellows are ground on
18 the outside, so that they have an absolutely smooth surface
when closed.
Material
Good resistance to light and atmospheric conditions and are
30 well suited to outside use. If emphasis is on oil or coolant pro-
tection in your area of application, then we recommend the
use of NBR rubber foil. Alternative materials are available for Rubber disk bellow
high temperature requirements.
We supply the bellows in 5 mm graduation up to a diameter
32 of 200 mm and in 10 mm graduation above this.
The extended length of the rubber disk bellows can be up to
10 metres.
Mounting
38 Rubber disk bellows are fastened the same as other
bellow types with sleeve or metal flange.
Design
With large extension length and horizontal installation, it is
46 usually necessary to use additional guide elements. In the
most simple case, the bellows are stabilized by internal
wire rings.
In more complex applications, guiding systems with rods
or cables can be incorporated internally externally to the
58 bellows.
When mounting these bellows please pay attention to
sufficient aeration.

result from the machining process.
X-Velo Dachabdeckung
The X-Velo Roof Cover System prevents the machine’s
08 interior from discharging material into the atmosphere.
Thanks to our adapted aluminium profile guide rails,
the roof cover can be installed easily on new or existing
machinery. The machine is sealed off and covered
effectively as a result of X-Velo’s construction features.

required. 02
Two different types are available:
ROLLER blind without housing - this type needs less

safety reasons when longer extensions are used and
especially when steel is used for the band material. They
are available in many variants.

The metal sections are flat or semi-circular aluminium, brass
or steel sections. They are bonded and riveted on a very tear
resistant synthetic carrier material
The sections have a standard width of 15 or 16 mm, the
height of the rods is between 2.0 mm (flat) and 3.0mm 18
(semi-circular). The link aprons are manufactured in a width
up to 3000 mm.

FLEXWALK
The FLEXWALK type is available in two section sizes. It is a
02 combination of extremely stable hollow aluminium sections
and a carrier fabric of synthetic or stainless steel band.
This is used when the customer requires an accessible solu-
tion. The aprons with a steel band as carrier material are
joined with a high-performance bond of the required
08 flexibility. These steel band aprons can therefore be used
permanently on roller blind systems as well.

DURASPRING
DURASPRING Spiral Springs
Spiral Springs are commonly used for the durable protec-
tion of ballscrews and shafts. DURASPRING Spiral Springs
02 are produced using spring steel. The steel strip is roll
formed to produce the spiral spring.
The advantages of DURASPRING are:
High quality spring steel
Tandem installation of multiple springs is possible
