Safety at a glance
Wood processing
The fact that woodworking machines have to meet special safety requirements is not surprising when looking at large saw blades and flying wood chips.
These are defined not only by the common safety standards, such as ISO 13849, but also by special C standards that apply only to woodworking machines.
To be able to comply with all standards without having to sacrifice performance in terms of machine output, you need a safety partner with expertise in the woodworking machinery industry.

Woodworking is an industry where machine safety is of particular importance. This is because machinery in this industry often has large, heavy and fast-moving parts that can cause injury if not properly maintained or operated. Woodworking machinery must therefore be designed and manufactured in accordance with current C standards to ensure worker safety.
The demands on woodworking and processing machines have been increasing for years, not least due to increasingly complicated control and operating modes of the machines. Modern woodworking machine should be versatile and at the same time enable maximum performance. In combination with the special normative requirements of the industry, this is a difficult balancing act for safety technology.
Some of the safety standards that apply to woodworking machinery include EN ISO 12100 (Safety of machinery - Principles for design) and EN ISO 13857 (Safety distances - Distances to prevent hazards arising from movements of parts of machinery). In addition, Appendix IV of the EU Machinery Directive requires all woodworking machinery to be assessed as safe by an external certification body.
DINA has many years of experience in working with the woodworking industry and specialises in adequately meeting all safety requirements through the development and production of high quality and reliable safety products:
Our applications for the safety of woodworking machinery
-
Edge-banding machines
An edgebanding machine has fast-moving parts such as glue syringes that can cause injury if not operated safely. heat from hot glue as well as crushing points when pressing on the plastic strip are the biggest hazards. Improper handling is also another hazard. It is important that the machine is properly maintained and operated and that all employees are instructed in the correct handling.
DINA's solution
Depending on the requirements and characteristics of the machine, there is a wide range of potential safety solutions from DINA for edge banding machines:
SAFELINE VARIO: The most complete safety solution for edge banding machines can monitor all protective devices and intervene in an emergency.
Emergency stop relay DNSR-2R2: This module stops the machine directly and safely in case of an emergency.
Rotation direction monitor DN3PR1: If an axis should rotate in the wrong direction, this device switches the machine off directly.
-
Machining Centres
There are numerous danger points with machine centres in woodworking. These include fast-moving parts such as saw blades and router bits can cause serious injuries. Improper handling and accidental splashing of glue are other hazards. There is also the risk of crushing and shearing injuries from unprotected workpieces and tools.
DINA's solution
Due to the significant differences in woodworking machining centres, it is difficult to find a general solution that works for every machine in this category. The SAFELINE VARIO safe small control unit would fit best into the system here. Due to its modularity and flexibility, SAFELINE VARIO can be ideally adapted to your machine.
For smaller machines that need to fulfil fewer safety functions, the modules of the SAFEONE series are also suitable. It is best to arrange a meeting directly with one of our safety experts for optimal advice.

Pressure beam saws
Pressure beam saws entail some safety-relevant risks. The central danger points are: Injuries from contact with rotating parts, injuries from unattended movements of the saw, injuries from contact with the saw blade and injuries from maintenance work carried out by unqualified personnel.
DINA's solution
The perfect solution for pressure beam saws is the SAFELINE VARIO in combination with the DNSL-INV extension module. The add-on module monitors the exact position of the saw blade at all times and compares it with preset safety positions. Unusual movements and deviations are thus directly detected and passed on to the operator.
-
Panel sizing saws
The main hazards of panel-sizing saws are mainly injuries caused by contact with the saw blade, as well as injuries caused by unintentional starting of the machine. There is also a risk of injury from uncontrolled movements of the panel-sizing saw during operation. There can also be danger from the uncontrolled removal of cutting residues, so a safety solution that covers many functions is needed.
DINA's solution
The SAFELINE VARIO module in combination with any peripheral modules, depending on the safety functions required, offers the best safety solution for panel-sizing saws. SAFELINE VARIO is a modular, compact safety control, assembled according to the application, which can monitor up to 30 axes.
A more cost-effective solution would be the DNSR-2R2 emergency stop relay, which does not have nearly the range of functions as SAFELINE VARIO. It only enables the machine to be switched off quickly and safely in an emergency by interrupting the power supply.
-
Trim saws
With trim saws there are some hazards that need to be considered. These include the risk of injury from the unprotected sawing area and the risk of injury from unforeseen kickbacks. It is important that all safety precautions are taken to minimise these risks.
DINA's solution
The SAFELINE VARIO central module is also the ideal solution for trim saws. The module offers reliable and flexible safety and is also easy to install and configure. Depending on the specific trim saw in which the module is to be used, the safety solution can be expanded with up to 15 additional modules. It is a robust and durable solution that works reliably even with frequent use.
-
Multiblade circular saws
With multiblade circular saws there are dangers due to the fast rotating blades, which can cause injuries, as well as due to the uncontrolled workpiece transport. In addition, collisions with the saw blade or the tool head can occur.
DINA's solution
As with most other saws, a combination of SAFELINE VARIO and various additional modules is recommended for multi-blade circular saws, depending on the specific requirement by the machine.
A more inexpensive solution, which is particularly suitable for smaller multi-blade circular saws, is the DN3PD2 speed monitoring module. In combination with the DNSR-2R2 emergency stop relay, this solution can also provide maximum safety.
-
Diagonal saws
The main hazards with diagonal saws are injuries from contact with the saw blade, injuries from contact with moving parts of the machine and injuries from handling the material being sawn.
DINA's solution
An ideal solution for diagonal saws is the phase monitor DN3PW1 in combination with an emergency stop relay DNSR-2R2. This combination provides a safe shutdown of the machine in dangerous situations and monitors the phasing of the system at the same time.
-
Finger jointing machines
The greatest dangers with finger jointing machines are injuries caused by the unprotected working area, especially by the moving tool carrier and tools. There is also a risk of damage to the machine due to improper use or maintenance errors. There is also a risk of fire or explosion from handling flammable materials or from electrical faults.
DINA's solution
The DN3PS2 standstill monitor is a popular choice for all types of finger jointing machines. The device ensures that the machine only runs when all guards are properly closed. -
Sanding machines
Sanding machines can present a number of hazards, including: Injuries from rapidly rotating parts, dust and smoke generation, injuries from inadequately secured workpieces, and fire and explosion hazards from increased friction and generated heat. It is therefore important that the machine has the properly fitting safety solution.
DINA's solution
The SAFELINE VARIO with the DNSL-INV offers a comprehensive safety solution for grinding machines. The DNSL-INV add-on module detects unexpected movements of the tools and thus ensures a fast and reliable emergency stop. Together with the emergency stop function of the SAFELINE VARIO, which enables safe emergency shutdown of machines and systems, this solution offers maximum safety for the operation of sanding machines.
-
Front-end processing machines
Front-end processing machines present many different safety hazards: Hazards from unprotected moving parts, hazards from unexpected restarts after an emergency stop, and hazards from inadequate shielding.
DINA's solution
A suitable DINA safety solution could be the SAFELINE VARIO with the DNSL-INV add-on module. This solution provides a fast and reliable shutdown of the machine in dangerous situations and allows access to moving parts only during safe operation.
-
Surface Planers
The central points of danger with surface planers include injuries caused by rotating parts, injuries caused by workpiece transport and injuries caused by inadequate safeguarding of moving parts.
DINA's solution
An ideal DINA solution for the safety of surface planers could be the DNSR-2R2 emergency stop relay. Most jointers are usually simpler and do not require a large solution, such as SAFELINE VARIO. The emergency stop relay monitors the central safety functions and switches the machine off safely as soon as a dangerous situation is detected.
