Wire breakage at the knot due to dry or poorly oiled wire
Poorly or improperly oiled black-annealed automatic baling wire can cause major problems at the auto tie assembly on the baler often resulting in excessive wire breakage.
Poorly oiled wire increases the back pull on the tier because the wire drags as it goes over the pulleys and through the guide tubes. Wire dragging puts added load to the tier and often prevents sufficient wire being delivered to the tier to make a correct knot.
This condition can often be observed by examining the broken wire knot. If the knot looks particularly dry and shiny and the twists very tightly wound there is a good chance that the wire has not properly oiled.
Some manufacturers of black annealed automatic baling wire shortcut the oiling process by spraying a light oil film on the outside of the wire on the carriers.
At Coastal Wire Company, we understand that it is necassary to FULLY oil the coil--inside and outside. All of our wire is dipped into a tank of oil, which is vigorously stirred by compressed air for a minimum of ten minutes. This process gives sufficient time for the oil to penetrate the entire coil, and to be absorbed by the porous black oxide skin on the wire surface. The wire coil is then set on a draining table where it drains for at least two hours in order to remove the excess oil.
We believe that the cost of making a properly oiled product is money well spent when you consider the cost and aggravation of bales breaking apart due to wire knot failures.
If you are not using Coastal Wire Company's FULLY oiled wire, check with your current wire supplier to find out how they oil their wire--you may want to reconsider your wire source.
