■ Belts Splicing

Generally there are ten methods of belts splicing as illustrated on the following diagrams. Depending on situations, we may suggest more suitable method considering the conditions of facilities and belts, in which case a special technique can be utilized

■ Kinds Of Splice

Scarf splice Scarf splice uses a similar splicing method with the overlap splice method. It is also called as seamless splice because of the smooth edge finish. Splicing can be done on business trip while on-site manufacturing is not available.	Overlap splice The most common splicing method using thermosetting. Standard technique is to set the width of 25mm at an angle of 90°. But the width and angle can be adjusted according to usage. Belt splicing can be done on-site by a technician. Business trip manufacturing is also available.
Butt Splice A splicing method which allows smooth upper edge (surface contacting the material) finish. The lower part (surface contacting the pulley) is joined using thermosetting with the same fabric as the belt or different kinds of materials. It has a minor defect which is the relatively short durability because the contact surface is rubbed out easily.	Two ply Laminated belt An effective splicing method to splice the two-ply using thermosetting, removing the thickness difference between the upper and lower fabric parts. Perfect for manufacturing process requiring extra smooth surface. Belt size should be within 100mm length due to the manufacturing difficulty.
Sawtooth wave splice This connection method is a method of heat-sealing the upper and lower reinforcements in the form of a saw blade using the blade.High strength of the joints as well as flexible benefits and the connections you can use a lot smoother surface also possible connections. we can perform a wide belt splicing in the field(up to 2,600mm).	PEEK spiral splice This connection method is a method for connecting the belt mainly of the shape of the mesh. Flexibility and breathability of the joints in relation to the use of Kevlar reinforcement mesh are widely used in the mesh belt excellent.
Smart loop(Bullnose) splice Very Similar to the PEEK spiral method. The loops do not require extra support materials as they are made by specially manufactured Para-aramid mesh. It has great permeability due to the simple sewing process. However, it is less flexible compared with PEEK and the process connecting with the pins can be slightly complicated.	Heavy duty fabric splice Using Para-aramid fabric as a support material for the connected parts and instead of metal pin, FRP pin is utilized making it perfect for high frequency oven belt.
Allgator splice As a splicing method using connecting metal loops which look like an alligator. It has been widely used in the past but now less popular.	Clipper laced splice Very similar to the alligator splice method except of the shape of the connecting loops.

Sewing Industrial Lamination Belts

■ Lamination Belts

Lamination belts have the following excellent features compared with other one-ply glass or Para-aramid belts :

• Flexible joining parts and outstanding durability
• Extra thin joining parts and minimized occurrence of transferring in the joining parts
• Flexibility of joining parts preventing meandering and superior operation stability
• Excellent form changeability and top surface quality
• Excellent antistatic feature
• Can be used continuously at temperatures between -73℃ and 260℃
• Can be manufactured with the width up to 2.4m

■ Types of Basic Style

• L-6 : Total thickness 0.15mm, (Nominal thickness 0.075mm x 2ply)
• L-9 : Total thickness 0.23mm, (Nominal thickness 0.075mm x 3ply)
• L-10 : Total thickness 0.25mm, (Nominal thickness 0.125mm x 2ply)
• L-15 : Total thickness 0.38mm, (Nominal thickness 0.125mm x 3ply)
• Processing the edge is available (wrap or strip)
• Belt guide is available for one side or both (Para-aramid profile or buttons)

■ Spliced Parts Features

Previous belt splice has several defects such as stiffness from two-ply and meandering of spliced parts, which lead to poor quality. To eliminate these defects, this product use thermosetting method on the thin PTFE coated glass fabric two or three fold, which improve the flexibility of spliced parts and minimize the meandering.

Belt Specification

Laminated Belt

■ Laminated Belt

Laminated Belt or Composite Belt has been created to eliminate several defects of previous belt splice, such as stiffness from two-ply and meandering of spliced parts, which lead to poor quality. Its utmost features include the improved flexibility of spliced parts and reduction of the meandering incidence of spliced parts through thermosetting method. This is done on the thin PTFE coated glass fabric by two or three fold.

■ Types of Laminated Belt

• L-6 : Nominal 0.075mm PTFE Glass Fabric 2 ply - Thickness 0.15mm
• L-9 : Nominal 0.075mm PTFE Glass Fabric 3 ply - Thickness 0.23mm
• L-10 : Nominal 0.125mm PTFE Glass Fabric 2 ply - Thickness 0.25mm
• L-15 : Nominal 0.125mm PTFE Glass Fabric 3 ply - Thickness 0.38mm

■ Benefits

• Flexible spliced parts and outstanding durability
  Extra thin joining parts and minimal occurrence of meandering in the joining parts
• Flexibility of joining parts preventing meandering and superior operation stability
• Excellent variance and top surface quality
• Excellent antistatic feature
• Can be used continuously at temperatures between -73℃ and 260℃

■ Product Standards

Maximum width and length of available belt

• Width : up to 2000mm
• Length : No limit

Temperature for continuous usage

-73℃ ~ 260℃

Splicing method

For splicing method of belts please see the illustration on the left. It has the same sealing strength as the joining parts and main body fabrics when completed. This method enables smooth touch and minimum thickness difference in the spliced parts.

Belt Edge Supporting Technique

In order to prevent the ply fray and support the machinery strength, one of the following three methods can be selected and applied when the belt is installed and operated.

Common Edge Support Materials

Safety equipments can be attached on one side or both sides to prevent the meandering and the operation stability

Prevention of Belts Meandering

Pin, grommet or Para-aramid profile can be attached, which will pass through the grooved pulley and thus preventing the belt from transferring on one or both edge. Applicable usually for under the width of 1,000 mm.
