Technical Tips
Clipper® Wire Hooks: How to Achieve the Optimal Splice
 |
Select the proper hook based on the belt thickness and pulley diameter (see hook selection chart).
- If belt has an impression cover, skive end prior to measuring thickness for hook selection.
- Hook is properly sized and clinched when:
| A. |
Hook legs are parallel. Loop should not have a light bulb shape. |
| B. |
Hook points slightly penetrate opposite side of belt (.005"-.015"). |
| C. |
1/3 - 1/2 of the wire diameter is embedded into the belt. |
| D. |
When installed, the 'knuckles' of the hook should not be higher than the legs. |
- Leave 1/4" on each edge of belt unlaced. This guards against end hooks being pulled out.
- Use one more hook on leading end than on trailing end.
- Chamfer trailing edge.
- Splice should be uniformly embedded across the entire width of the splice.
- Edges of the belt should line up when the laced belt ends are connected.
- Run fingernail across loops of splice; loops should not move.
Good Clinch: Hook legs are parallel, half of the wire diameter is embedded into belt, and hook points have penetrated through belt.
Over Clinch: Functional, but not an optimal splice. Try to avoid over clinching in the future.
Under Clinch: If belt is still in lacer, embed fasteners further. If belt is out of the lacer, reinsert splice in the hook retainer/face strip, and embed fasteners further. |
