A Spanish SME has designed a security system to protect workers working with Heidelberg printing machines. Advantages of the system are safety, universality and cost. The company is looking for work security companies or machine distributors interested in the technology.

The safety system developed by a Spanish company can be mounted in Heidelberg printing machines, type T (26x38 cm) and type GT (34x46 cm). Although these machines are several years old, due to their quality and toughness, they still form nowadays a remarkable proportion of printing machines in Europe. The system will allow owners of these machines to comply with the law as regards safety at work (European directive 89/655/CEE)

The safety system principle consists of putting removable protections around the machine in such a way that it prevents workers from getting into the hazardous zone and, nevertheless, allows them to pay attention (visibility) to the functioning machine.

For the system to work, it is necessary to mount a triggering device on the machine. Whenever someone removes any of the machine’s protections, this device will immediately declutch the motor and let the brake operate, thus avoiding every hazard.

Innovative Aspects:

These machines (in their original design) have deficiencies in safety aspects that, although in small numbers, cause serious accidents. Several solutions to that lack of safety have been proposed, but they have failed to achieve the desired results. The safety system proposed here does achieve absolute protection of workers, as well as conformity to laws

Main Advantages:

- Absolute protection of worker.

- Minimal annoyance during machine supervision.

- Universality.

- Low cost.
