Loading... Please wait...The XU Range of thermal binding machines is our most popular range. The range includes the XU138 which has one heat plate, the XU238, which has two and the XU338, which has three. Each plate is activated independently by a magnet when it comes into contact with a Unibind steel spine product. This means that if someone is using one plate, someone else can use the second or third plate independently. However, as each heat plate is 38mm wide, you are not restricted to only binding one book per heat plate, but can put a number of documents in the same compartment at the same time.
