  Question  
 
Do you have any Literature available?

We have two types of publications. A full sample folder detailing the jointed covering range and a brochure with the jointed covered range overview.

 
 
Do you have standard Price Lists?

Given the infinite combinations of belt type, cover type, thickness and fabrication this is not possible. We can however produce a price list specific to your demands. On this we can list all the information you need to identify any of the belts on your production line. For further details contact the Sales Department.

 
 
How can I have a thicker cover than my pullies allow?

This can easily be overcome by cross slotting. We can machine a slot across the cover at different depths and pitch. This allows the cover to “open” as it travels around the face of the pulley. This in turn relieves the cover of excess tension and stops any cracking or splitting. (Custom Fabrication)

 
 
How do I know what cover type to choose?

In general terms, the harder the cover, the more abrasion resistance, with less grip on the product.  Conversely, the softer cover will offer more grip but less abrasion resistance.  The hardness of the cover depends a lot on the product being pulled. Is the present cover performing satisfactorily ? Do you need more grip ?  Are your belts wearing out too quickly ?  Answering these questions should help you choose the best cover type from our range or alternatively contact our Sales Department for advice.

 
 
How do I stop crushing damage to a delicate extrusion?

There are three possible ways:

  1. Use a soft cellular material (Jointed Covers) that will “wrap” around the extrusion giving greater contact with the product.  This will require less clamp pressure on the product, and in turn less product damage.
  2. Use a Cushiontex® construction.  This is a combination of a solid top cover and a cellular base.  This again offers a “wrap” effect on the product and requires less clamping pressure.  Additionally, this combination also offers greater abrasion resistance and longer belt life.
  3. Use a profile in the belt covering.  This can be machined into the top cover (Custom Fabrication) to precisely fit your product.
 
 
How do I work out the size of the belt on my equipment?
  • Identify what construction of belt it is i.e. Poly Vee, Timing, Flat etc (Base Belts)
  • For Poly Vee identify the length and rib pitch. (Poly Vee)
  • For Timing Belts count the teeth and ascertain the tooth pitch to calculate the length. Take care as some imperial and metric pitches are very similar. Eg L section 0.375” (9.525mm) is very close to T10 (10mm). To double check, measure over 10 pitches. This allows the differential to be seen more clearly.
  • For flat belts, measure the belt length in sections on a flat surface, marking it out as you go.
 
 
How thick do I need to make my belt cover?

This is generally dependent on three factors:

  • The diameter of your pulleys.  The smaller the pulley, the thinner the cover needs to be (Pulley Diameters) Thicker covers may be needed where smaller products are run on larger haul offs. This could be due to the booms not being able to close sufficiently to grip smaller products.
  • An extra thick cover may be necessary, if the belts require profiling to suit a deep section.
 
 
I need a very complex profile machined Into the covers for a new section.

Send us a drawing of the cross section of your product, and we will produce a drawing of the belt(s) required. We can also produce these from a sample of your product.

 
 
I only know the manufacturer & model of my haul off?

No problem. We hold comprehensive data on most manufacturers and machine types. Talk to our Technical Sales Department.

 
 
My haul off has Poly Vees without ribs the whole width of the belt.

For some of the older wider units this is quite possible. Accurately describe and/or sketch the rib layout. We can machine the ribs on your new belts in the same way.
