Stringing the Belt
Textile belts such as Plylon Plus®, Plylon®, Raider ®, Pathfinder®, etc. that have been slit from a full-width slab at the factory
should be spliced with the factory-cut edges on the same side of the conveyor (Goodyear Engineered Products identifies these
edges with white paint applied at the factory after slitting). The factory-edge side of slit belts will be identifies by painting
“Factory Edge” on that side and a solid white 3” strip will be painted across the full diameter of the same edge.
To minimize side travel on steel cord belt rolls, it is recommended that rolls be strung onto the conveyor in the exact sequence
they were manufactured.
Tensioning
Once the belt has been pulled onto the conveyor system, it must be tensioned prior to splicing to facilitate correct positioning
of the take-up and to eliminate sag. The tensioning operation takes place at the location where the last splice will be made.
After final tensioning, clamps are placed on each end of the belt. These are made of steel and have a clamping surface as
indicated in Figure 5.
Tension is applied by means of a power device, which is used to pretension the belt before “clamping off.”
When tension measuring load cells or scales are used, they are rigged to measure the pull on the take-up pulley. The belt is
pulled until the load cells or scales register a tension equal to or slightly greater than the recommended take-up force. Make
allowance for an amount of belt necessary to correctly position the counterweight from this point.
