How Are 3 1/8" Thermal Paper Rolls Manufactured ｜Slitter Rewinder Machine

#thermalpaper #slitterrewinder #industrialmachinery Ever wonder how a 3 1/8-inch thermal paper roll is actually made? Most people think the width comes from the paper core or the rewinding shaft — but that’s not how it works. In this video, we break down the real manufacturing process of 3 1/8-inch thermal receipt rolls (also known as 80mm POS paper rolls). You’ll see how a wide thermal paper jumbo roll is converted into precise narrow rolls using a thermal paper slitter rewinder. Here’s what we cover: Why the finished paper width is controlled by the slitting blades, not the core The exact conversion: 3 1/8 inches = 79.375 mm Step-by-step process: jumbo roll unwinding, blade setup, slitting, rewinding, and final inspection How operators use blades and precision spacers to set the correct cutting width Common mistakes that cause incorrect paper width What to check on a finished thermal receipt roll Whether you work with POS paper, cash register paper, or thermal ticket rolls, understanding the slitting process is key to consistent quality. Watch till the end to see how the same machine can also produce 2 1/4-inch rolls by simply changing the blade and spacer arrangement.
