Tooth Chain Program

With the extensive tooth chain program Renold offers the ideal components for your glass production.
With unparalleled product quality and expert service. Inverted tooth conveyor chains, whether as an IS-machine conveyor or a cross conveyor in front of the furnace offer ideal guiding characteristics: low-vibration, smooth operation, high production speeds, minimal sliding resistance and extended service-life. High-precision drives with inverted tooth chains ensure smooth processes in sheet glass production. The inverted tooth chain is a cohesive network of sturdy links. It is made of numerous link plates and profile pins. The result: a powerful and flexible chain drive that can be perfectly  adapted to the task at hand. HPC- and Biflex tooth chain drives: space-saving and variable in type, design and width, slip-free and silent, simple assembly / disassembly.

Now Trending: Stainless Inverted Tooth Chains

Stainless steel for increased efficiency and reduced waste

The leading European technology specialist for inverted tooth chain applications, RENOLD, stands for quality, individuality, and innovation. This year’s focus at the Glasstec: stainless steel inverted tooth chains.  

•Stainless steel inverted tooth chains increase energy efficiency in the production process
•Inverted tooth chain: Specialist for drive and transport in glass production and processing 

“Admittedly, the designation ¿'stainless inverted tooth chains' may be confusing – because the advantage of our stainless steel inverted tooth chains for the glass industry are in another area,” emphasizes Uwe Gillert, glass industry manager for inverted tooth chain manufacturer RENOLD. As stainless steel has a lower thermal conductivity than standard steel, the interface temperature between the burning hot glass and the inverted tooth chain increases. “This way, base cracks in the glass are reduced, which results in minimal waste during production,” explains the inverted tooth chain specialist. Preheating the inverted tooth chains is also no longer necessary. For a standard IS-machine, this can save energy costs of tens of thousands of euros per year. “We will present current calculations at this year's Glasstec in Düsseldorf, Germany,” Gillert reports.

Of course, the stainless steel inverted tooth chain also features the classic advantages of the inverted tooth chain design: The interlocking power transmission between the inverted tooth chain and the sprocket ensures slip-free drive operation. The inverted tooth chain engages in the sprocket with minimal impact and minimizes energy loss. And the 2-part rolling pivot joint features virtually zero friction losses. This results in efficiencies up to 99% – in production lines with many operating hours and high speeds especially, the use of inverted tooth chains can increase energy efficiency in production.
Laser-welded rolling pivots offer major advantages in the glass industry in particular. The smooth contact surface on both sides of the inverted tooth chain creates a gap-free transition between the inverted tooth chain and the infeeding and transition points. This process also reduces the risk of pin breakage.
