5 Tips for Splicing Folder Gluer Conveyor Belts

Splicing folder gluer conveyor belts is a crucial step in new belt installation. Since many belts arrive as flat strips of rubber, it’s up to you to join the belt into a loop that can fit on your conveyor system. When splicing belts, it’s vital to form a strong connection between the two ends so they can withstand a lifetime of wear and tear. Use these five tips for splicing folder gluer conveyor belts.

Know the Different Types of Splicing

There are many types of splicing methods, some of which tend to work better on larger conveyor belts. For folder gluer belts, your choices are between mechanical fasteners and a process called endless (or vulcanized) splicing, which chemically bonds the two ends.

Don’t Use Mechanical Splices With Small Particles

Unlike endless splicing, which creates an almost seamless loop, mechanical fasteners have cracks, gaps, and openings. These gaps are perfect traps for debris and oil, so don’t use them if they’ll be in direct contact with glue, liquid, or anything that crumbles.

Use Bias Splicing To Reduce Noise

Bias splicing is a technique that connects the two ends of the belt at an angle. This means the splice travels over the pulley gradually, instead of all at once. A bias splice is less likely to create bumps and noise.

Cold Splice in Gradations

Cold splicing is a type of endless splice that uses adhesive and pressure to join the ends of the belt. It differs from hot splicing because it doesn’t involve using heat. The key to a solid cold splice is to peel back the layers of the belt ends in sections, like a staircase. Fit the two staircases together, one on top of the other, and you’ll have a much stronger connection than a splice with only one step or layer.

Don’t Forget the Cover Strip

For cold splicing in particular, it’s very important to cover the splice with a guard on both sides. Failing to do so will weaken the belt by exposing the splice directly to stress and friction.

Following these tips for splicing folder gluer belts will help you get started using your new folder gluer belts much more quickly than paying for an outside service.
