Electronic Corner Cutting/ Rounding Machine
Electric Corner Rounding Machine
Designed specifically for heavy-duty use, the MÜHLEN L777 electric paper corner rounding machine can round the corners of 500 sheets of paper at once. Capable of 60 presses per minute, the model has a motor power of 180 Watts. With its metal body and steel internal component system, the model is built to be durable for many years of use.
Heavy Use Throughout the Day
The fully professional MÜHLEN L777 model is specially manufactured for continuous use throughout the day. With the help of the cylinder on top, the user can easily choose among 7 different blades, and can operate more comfortably with both hands by using the cutting button or the cutting pedal.
Beyond Expectations
This model features an extremely powerful motor and cutting blades made of special steel. This allows the user to easily remove the cutting blades and sharpen them when needed. Besides rounding paper corners, it can also round the corners of PVC, photographs, MDF, labels, cardboard and fabric at the angle of the user's choice.
7 Different Angle Blades
The MÜHLEN L777 has 7 different blades at R3, R4, R5, R6, R7, R8 and R10 angles, which can be easily selected by turning the cylinder on top of the machine. Capable of cutting all kinds of materials with ease, the model can smoothly round the corners of cardboard, photographs, fabric and more, in addition to paper.
500 Sheets at a Time
This time-saving electric paper corner rounding machine can round the corners of 60 stacks per minute, with 500 sheets of paper per stack, to the desired degree. Extremely sturdy, the model is built with a fully metal body and steel internal components. With a cutting throat height of 70mm, it can easily cut other materials besides paper.

User Friendly
To prevent paper stacks or other materials from slipping during cutting, an automatic clamping (press) system applies pressure to the stack, offering a great advantage. If preferred, the user can use the foot pedal to keep both hands free. (The power switch must be at position I for button operation, and at position II for pedal operation.)
Wide Range of Use
The MÜHLEN L777 does more than just round paper corners. It can also be used with ease on PVC film, cardboard, chipboard, photographs, MDF, fabric and many other materials. The emergency stop button is used to immediately halt the machine during pedal operation. An Allen key set for the adjustable tray guards and other parts is shipped together with the product.
