A Quick Guide to Conveyor Belt Endlessing (Splicing) - Monster belting (2024)

We realize that as a business, one of your leading priorities is to minimize downtime and maximize output. That’s why we recommend splicing as a reliable and quick method of fixing the conveyor belt when it breaks down.
A Quick Guide to Conveyor Belt Endlessing (Splicing) - Monster belting (1)Endlessing, or endless splicing, is the process of joining belt ends using a combination of techniques such as heat and pressure and also chemical bonding.
While mechanical splices are also quite effective at joining belt ends, endless splicing still rules because it can offer results even in demanding environments and in settings that require minimal downtime, ensuring effectiveness in splicing despite the condition of your belts.

Endless Splicing – What Makes It Effective?

If you are looking for a method to create strong, long lasting bonding between belt ends, Endless Splicing is the way to go.
This method of belt fabrication is perfect industries that need low profile splices without marking, or diminishing, the looks of conveyors. For instance, conveyor belts in the food and sanitary industry need to be spliced neatly and faultlessly for cleanliness and better effectiveness.
It involves joining two ends of a length, preferably using the hot vulcanizing methodology. Also, use the HIC method to ensure durability of the splice. V-shaped (aka diamond shaped) joints make for a stronger splice and are highly recommended. The additional length needed for endlessing should be calculated using this formula:
Splice Length = W + 150 (N-2) + 25mm
Here, W is width of belt (in mm), N is the number of plies.

What is the formula for conveyor belt splicing? ›

The overall splice length will be given by L = X + [S. (n-1)] Where n is defined, as the number of plies and s is the step length. All splices shall be made by stripping back the plies at the two ends of the belt in the required manner.

How to do conveyor belt splicing? ›

Installing and Splicing Steel Cord Conveyor Belts
  1. Aligning the Belt Ends.
  2. Stripping Away the Cover Stock.
  3. Isolating Individual Cables.
  4. Assembling the Cables.
  5. Closing the Splice.
  6. Vulcanizing the Splice.

What is the angle for conveyor belt splicing? ›

The typical angle of a step splice is 17 degrees, or 0.3 x belt width (B). This over-length needs to be taken into account when determining the endless belt length.

How to join a conveyor belt together? ›

Endless splicing joins the two belt ends together either through heat or chemical activation, making the belt a continuous, endless band. The alternate method, mechanical fasteners, physically attaches a row of fasteners to each belt end. These fasteners are then meshed together and connected with a hinge pin.

Is belt splicing a hard job? ›

“Belt splicing work is difficult and requires unique skills which impacts its attractiveness. A lot of that has to do with the lack of recognition for the trade, which is what we're aiming to change,” Mr Warren explains.

How to joint a belt? ›

Butt joints are made by placing the two ends of a belt together and applying a 50mm wide piece of material underneath. This is then welded together ensuring the top surface is nice and flat.

What is the best angle for a conveyor belt? ›

With a plain belt (with no protrusions) we usually say the maximum angle is 20°. If you need to go steeper than that then a 15mm chevron pattern belt will take you up to 32°. If you need to go still higher than that, a troughed and flighted belt can go up to 45° for ordinary excavated material.

What degree is a belt splice? ›

The most common splice angle is 17 degrees, which is an equivalent bias length of 0.3 x belt width.

How do you cut a conveyor belt straight? ›

Slitting machine

Companies specialising in conveyor belts usually own an industrial slitting device. It has a table with rollers that feed the belt to a stationary blade. This process cuts the belt fast and accurately; even narrow belts are done easily.

What are the techniques for conveyor belt splicing? ›

The step conveyor belt splicing method has two main techniques: Hot or cold (glued) and glued cold bond. Hot or cold glued is best utilized for thermoplastic belt styles and glued cold bond is commonly used on rubber belts.

What is belt splicing? ›

Conveyor belt splicing is the process of joining together two pieces of conveyor belt. Usually, this is done to either elongate the original conveyor belt or to repair a torn or damaged conveyor belt.

How do you join the ends of a conveyor belt? ›

Endless splicing bonds two belt ends together by applying pressure with heat, allowing the thermoplastic material to flow and then bond together for a strong splice as the material cools and re-hardens.

What is the formula for belt pull? ›

Belt pull equals total weight times frictional coefficient between the bottom of the belt and the top of the slider bed. Then, convert this to required power. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min.

What is the formula for calculating the belt length? ›

A more precise calculation formula is: (1) L=π(R+r)+2a+(R-r)^2/a (2) L=π(R+r)+2a+(R-r)^2/4a Where L is the belt length, R and r are the radii of the two pulleys respectively, and a is the distance between the centers of the two pulleys.

What is the belt ratio formula? ›

Belts: A belt decreases speed in proportion to the diameters of its pulleys or sheaves. The pulley on a motor shaft is typically smaller than the one on the machine shaft. The speed ratio is R = DL /DS, where DL = diameter of large pulley, and DS = diameter of small pulley.

What is the formulation of conveyor belt? ›

Generally, conveyor belts are made from a rubber or plastic compound combined with one or more layers of fabric material or different diameters of steel cables. A conveyor belt may be made from polyvinyl chloride and fabric such as polyester or styrene-butadiene rubber and several layers of polyester or nylon fabric.
