This type of baler is either either auto-tie or Manual-Tie. An automatic horizontal baler is fed by a conveyor. After the machine dispenses retaining wires, it compacts the material into bales, and then pushes the bales out on rollers. A manual-tie baler requires the retaining wires to be manually placed around the baler. After a bale is formed, the door of the baler must be opened for the bale to eject. Auto-tie horizontal balers are good for large scale projects and places such as recycling plants. Manual-tie horizontal balers work well for smaller scale recycling.
