Open Spiral Belts: production, application and expertise

What are open spiral belts

Open spiral belts are metal conveyor belts that consist of woven spirals, manufactured with great precision and craftsmanship. The unique feature of these belts is their open structure, which allows air, heat, liquids or small particles to pass through the belt unhindered. This makes them particularly suitable for production processes where ventilation, temperature resistance or sterilization are essential.

Thanks to the flexible construction, each spiral and insertion can rotate independently, guaranteeing optimal flexibility and a straight belt run. In addition, open spiral belts are available in various materials and wire sizes, making them suitable for use in a variety of industrial conditions.

Key benefits of open spiral belts

Open spiral belts offer numerous advantages for companies and production lines:

• Efficiency: The open structure promotes air circulation and heat transfer, essential in ovens, drying installations or sterilization tunnels. Positively driven variants prevent tire slip and ensure a constant and straight belt run.
• Sustainability: Made of robust materials such as stainless steel or special alloys, resistant to temperatures up to approximately 1,150°C and designed for long-term use.
• Safety: The construction of the belts reduces the risk of product damage and makes transporting sensitive products reliable.
• Ease of maintenance: Thanks to the robust construction and wear-resistant materials, maintenance is minimal. The design also offers easy replacement options for parts such as gears or product carriers.
• Cost-effective: Standard and crushed versions in particular offer excellent value for money, while customized options are available for specific applications.

Applications in various sectors

Open spiral belts are widely used and are used worldwide in various sectors:

• Food industry: Oven belts for bread and pastries, cooling and baking lines for potato and vegetable products, and frying lines.
• Pharmaceutical industry: Sterilization tunnels and drying systems for safe processing of sensitive materials.
• Industrial processing: Drying tunnels for insulation materials, tempering processes in the glass industry, and metalworking applications such as hardening, sintering and brazing.
• Special transport tasks: Acquisition installations with sharp curves or minimal takeovers, transport at high temperatures or in demanding production environments.
