Paper cutter
Encyclopedia
A paper cutter is a tool often found in offices and classrooms, designed to cut a large set of paper at once with a perfectly straight edge.

Description

Paper cutters can be at least 1 feet (30.5 cm) in length on each side for small work, though they can often be longer than 2 feet (61 cm) on each side. Industrial cutters used in design workshops can be found 30 inches (76.2 cm) in length. The surface will usually have a grid either painted or inscribed on it, often in half-inch increments, and may have a ruler
Ruler
A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines...

across the top. At the very least, it must have a flat edge against which the user may line up the paper at right-angles before passing it under the blade. It is usually relatively heavy, so that it will remain steady while in use.

On the right-hand edge is a long, curved steel blade, often referred to as a knife, attached to the base at one corner. Larger versions have a strong compression coil spring as part of the attachment mechanism that pulls the knife against the stationary edge as the knife is drawn down to cut the paper. The other end of the knife unit is a handle. The stationary right edge of the base is also steel, with an exposed, finely-ground edge. When the knife is pulled down to cut paper, the action resembles that of a pair of scissors, only instead of two knives moving against each other, one is stationary. The combination of a blade mounted to a steady base produces clean and straight cuts, the likes of which would have otherwise required a ruler and razor blade to achieve on a single page.

A variant design uses a wheel-shaped blade mounted on a sliding shuttle attached to a rail. This type of paper cutter is known as a rotary paper cutter. Advantages of this design include being able to make wavy cuts, perforations or just score the paper without cutting, with the use of various circular blades. It is also almost impossible for the user to cut him/herself, except while changing the blade. This makes it safer for home use. Higher-end versions of rotary paper cutters are used for precision paper cutting and are popular for cutting down photographs.

An even simpler design uses double-edged blades which do not rotate, but cut like a penknife. While cheaper, this design is not preferable for serious work due to its tendency to tear paper, and poor performance with thick media.

Safety

Most paper cutters come equipped with a finger guard to prevent users from accidentally cutting themselves or severing a digit while using the apparatus. However, injuries are still possible if the device is not used with proper care or attention.

Future

With the development of technology and the demand of printing production, the further of paper cutter will be the larger cutting area and more intelligent directions. According to the paper cutter manufacturers introduced in addition to CNC cutter, and other digital program-controlled, intelligent product upgrade, the large format paper cutter is the future focus.

Printing, packaging and other related industries is the cutter' market, It has saved a lot of labor and production costs, according to cutter manufacturers, currently parting cutter has a cutter of the first mechanical history, a variety of electric paper cutter, automatic cutter, CNC automatic cutter, and other program-controlled automatic cutter, intelligent Paper Cutter will effectively improve the production efficiency and cutting accuracy.

Cutter Cutter manufacturers will be the future direction of vital importance, in addition to automatic paper cutter, CNC cutter, cutter and CNC programmable automatic paper cutter automation, digital technology has improved continuously outside , paper cutter automation peripherals, digital.
