How to Install Wire Hook Belt Fastener?

Inbelts is a wire hook fastener manufacturer in China. Here we will talk about how to install a wire hook belt fastener to join your belt. There are main tow steps, and you can learn from this article.

Proper Belt End Preparation

Make A Square Cutting

To prevent mistracking and extend splice life, it is critical to obtain a square cut off from the center-line of the belt. To achieve this, follow these simple steps:

• Prior to any work on your conveyors, make certain that the power has been turned off and the belt is "locked out"
• Mark the actual center points in belt width at intervals of 3 to 5 feet, for a distance of 15 to 20 feet back from the intended splice area (Fig. A).
• Using either a steel rule or a chalk line, mark the average center line through the points measured in Step 2 (Fig. B).
• Using a square, draw a line perpendicular to the average center line across the belt width (Fig. B).
• Using the a Cutter, cut the belt on the line drawn in Step 4.

Skive Impression Cover

It is important to skive off the impression cover of a belt in the area where fasteners will be applied. This allows the proper size fastener to be selected and for proper penetration/clinch.

Properly Installed Splice

The Hook is Properly Sized & Clinched

• Hook legs are parallel.
• Points slightly penetrate opposite side of the belt.
• 1/3 to 1/2 of the wire diameter is embedded into the belt.
• Hook knuckles are not higher than the legs when installed.
• 1/4" (6.4 mm) on each belt edge is left unlaced.
• One more hook is installed on the leading end than the trailing end of the belt.
• Trailing end of the splice is chamfered/notched.
• Edges of the belt line up.
• Hooks are secure in the belt.

Proper Belt Clinch

• Good Clinch: Legs are parallel, 1/2 of the wire diameter is embedded, points have penetrated opposite side.
• Over Clinch: Functional, but not optimal.
• Under Clinch: Embed further. Failure to do so will result in the hook opening up or in cracks in the knuckle area.

Proper Technique to Measure a Splice

Selecting the correct fastener based on the belt thickness, minimum pulley diameter, and application conditions is the first step to properly installing a splice. The second, and most crucial factor, is ensuring that the leg of the hook is embedded 1/3 to 1/2 its thickness into the belt. It’s easy to measure/inspect the splice for proper embedment; simply follow these four steps:

• Measure the belt thickness.
• Install the fasteners into the belt.
• Use a micrometer or caliper to measure the finished splice. Be sure to capture both the short leg knuckle and the adjacent long leg in one reading.
• If you have properly embedded the fasteners, your measurement should be between: 1) Original belt thickness plus the value in column C, and 2) Original belt thickness plus the value in column D. See the example and chart below.
