A wire baler machine is that which uses wire to tie up bales, as opposed to those which use straps that tend to be mounted on top or at the back of a baler. Wire can be used to hold the large, heavy bales in place, ensuring they are secure for transportation. This is done by feeding wire through the machine after the baling process has occurred and looping it underneath the bale through grooves at the bottom of the baler and tying it off in the middle.
Strautmann’s BP28 and BP53 are such balers, utilising wire to tie bales together. There is a video on the BP28’s page that demonstrates how to safely feed wire through the body and ensure all bales are secure and able to be unloaded by forklifts. There are also balers that automatically wire wrap bales as they’re fed through the baler’s system, though these tend to be much larger machines, such as the CB-S Channel balers.
Strap or Wire
You may wonder why there are two methods to holding bales together. This is because different materials are tougher than others and so require stronger support. Baling strap is generally less expensive and more flexible than wire, although wire is stronger on the whole. Strap is better at shock absorption however, more able to withstand being thrown about.
