Corner Rounding Machines

Round out those sharp page corners with a corner rounding machine. Corner Rounders feature rounded cutting dies that are used to cut the sharp corners off sheets, replacing them with an attractive rounded look. A corner rounder turns sharp, square corners into smooth, round corners instantly. There are several radii sizes available for most of the corner rounding machines, ranging in sizes 1/8" to 1/2", so you can create small or wide rounded edges. Corner rounding is ideal for eliminating the danger of sharp, square corners on plastic products, preventing paper corners from bending and tearing, or for creating a classy look of business cards, covers, menus, brochures and more. Most corner rounding machines can cut a stack of paper up to a 1/2" thick at a time, so there is no time-consuming individual page cornering.

Whether you need a small, desktop corner rounder for low to medium volume jobs or an electric floor standing corner rounder for a commercial print shop, there is a corner rounder for you. But there are so many options to choose from, so selecting which is best for you and your needs can be tough. In deciding what corner rounder to purchase, there are several factors to consider regarding your particular application needs. Before purchasing a corner rounder, ask yourself the following questions so you can learn how to choose a corner rounding machine.

① What is my volume?

The size of your jobs, and how frequently they occur, is an important factor to consider before you buy a corner rounding machine. The reason being that there are small tabletop units built for only a few stacks a month, as well as large floor standing electric and pneumatic machines for frequent high-volume jobs. The smaller, manual units take more physical effort while the electric require only the press of a foot pedal. In addition, certain models are capable of cutting through thicker stacks of product than others.

② What material will I be cutting?

The majority of desktop and floor standing corner rounders cut through paper as well as thin plastic such as laminate. However, only specific models can cut through materials including aluminum, leather, PVC, polypropylene, etc. Make sure the unit you decide on is capable of handling your specific intended applications.

③ How many sheets do I want to punch at one time?

Corner rounders are not all made alike. Different models will cut through different amounts of product. Corner rounder capabilities range from cutting 1 sheet at a time (small craft units) up to 4" thick stacks. Be careful with this one; higher prices do not always equal higher capacities, so be sure to check the capacity specification.
