PRISM® is the embodiment of state of the art technology from around the world, brought together for optimal performance and pricing. From computer controls made in the U.S. to European hydraulics, quality components have been integrated with a well established mechanical design. The result is a world class product at down to earth prices - accurate and reliable, designed for many years of trouble free operation.

Computer Control

The PRISM® computer control system automates the operation of each machine. It provides the ability to store cutting sequences and have the back gauge automatically position itself for each cut. Programs can be automatically uploaded from a network or with a USB device with CIP 3/4 files. No additional hardware or software is required.

The hardware and software for the computer control were developed by our C&P MIcrosystems division using the latest in microcomputer technology. All circuitry is manufactured to meet or exceed the highest microchip military specification standards. All electrical components undergo vigorous function tests as well as a computer controlled endurance test of the complete module.

Measurement can be entered into the computer, via a numeric keyboard, allowing for quick setup without moving the back gauge. All back gauge moments and limits are automatically set and controlled by the computer. Stored program measurements can be changed easily and quickly and measurements can be added or deleted as necessary.

The PRISM® computer offers the ability to record while cutting, thereby allowing the program to be automatically recorded while cutting the first lift.

The PRISM® MC-Basic computer can store up to 4000 program steps. The use of a non-volatile memory storage system assures no loss of data in the event of a power loss. The PRISM® MCC and TFT units offer a virtually unlimited cut storage capacity and complete networking.

Measurement Display

The MC-Basic computer offers an easy to read digital display of exact back gauge position and the next cut position that is stored in the computer's memory. Measurement can be displayed in the metric or inch system to three digits.

Measuring System

PRISM®'s industry standard direct rotary measuring systems uses a rotary encoder/pulse generator connected to the lead screw. Back gauge movements are transferred to the computer control electronically.

The system automatically compensates for wear on the lead screw, spindle condition or by changes in the back gauge drive mechanism. Therefore, the highest possible precision is maintained for many years.

Cutting Line Indicator

Optical (light line) and mechanical (clamp edge) cut line indicators are provided as standard equipment. They provide a visual reference of the cutting edge of the knife and allow the setup of a cutting program according to the printed image or cut lines. They also provide a visual safety to prevent cutting in an image area.

Chrome Main and Side Tables

The PRISM® is standard equipped with a chrome surface on the main table and also on all side tables (30" X 40" on all 45" and 54" machines). The high quality flash chrome surface provides a very stable surface and eliminates the maintenance necessary for steel or cast iron surface tables.

Air Table

Each PRISM® is equipped with an air table with built in blower. The air table provides a cushion of air that floats the lift so even the heaviest material can be moved, turned or aligned easily. The computer controls the air on the cutting table. The air turns on automatically when the back gauge moves in reverse and turns off when the back gauge moves forward. The air table can also be turned on or off manually.

One Hand Control

The back gauge can be positioned manually with advance/reverse-fast/slow keys for fast and precise setting of the back gauge position according to a printed image. With one hand control, the operator can hold the lift with the other, always keeping it in contact with the back gauge.

Back Gauge

The PRISM® has a very rigid and stable back gauge because it is guided on all four sides of the large table gib. Due to the design, the back gauge is carried (does not ride) over the cutting table guaranteeing long lasting precise operation.

Back Gauge Drive

The back gauge drive on each PRISM® cutter is equipped with a patented DC drive system.

Slot Closing Device

Each PRISM® is equipped with a slot closing device that covers the slot on the cutting bed and prevents the bottom sheets in a lift from being damaged or folded over by the slot. This device not only prevents damage to materials but also damage to equipment in further processing such as a blanket on a printing press if a folded sheet is run through undetected.

Hydraulic Clamp Pressure Adjustment

The infinitely variable hydraulic clamp pressure is easy to adjust. It offers a wide range of pressure with a low minimum pressure. A false clamp plate to protect difficult materials during cutting is provided as standard equipment and is easily fitted from the front of the machine.

Smooth Swing Cut

PRISM® has a smooth left to right cutting action so material is not forced against the side guide. The result is a smoother cut and prolonged knife life.

Knife Drive

The PRISM® uses a worm gear to drive the knife. The worm gear is the strongest of all common gear drives because more teeth are in mesh at the same time. The worm gear drive runs in an oil bath and requires no service other than oil changes.

PRISM® uses a hydraulic clutch to transmit the dynamic energy from the flywheels to the knife drive. This clutch system is designed for minimum wear, resulting in less maintenance for the PRISM® cutter.

Knives

Each PRISM® is supplied with three new high speed steel knives. Carbide knives can be supplied on request. Knives on PRISM® 30" and 36" machines are extra thick and have a higher grinding reserve for extended life and reduced knife costs than those offered by similar manufacturers. PRISM®'s knife lift device provides a simple and safe means of changing knives. The knife does not have to be manually lifted in or out of the machine.

High Speed Steel Knives

Provided as standard equipment are high-speed steel knives. High-speed steel knives are manufactured using tool steel, which is a higher quality of steel. The result is a knife with better accuracy and toughness. A high-speed steel knife is a stronger, more durable knife that has the unique ability to resist abrasion, stress, shock and impact.

High-speed steel knives will last up to three times longer between grinding than standard steel knives. This results in a reduction of downtime for knife changes with an increase in machine utilization. They will also reduce annual grinding costs with an increase in knife life.

Safety Features

Each PRISM® paper cutter has two-hand start and hold cut cycle circuitry with anti tie down and non-repeat devices to ensure safe operation.

Each machine is also equipped with a mechanical safety latch, which is an additional safety device that automatically locks the knife carrier in the upper position after each cycle. This device has an integrated electronic and mechanical self-check system.

Electric eye light barrier with self-check circuitry are standard equipment. The infrared light source which is used is long lasting and is not affected by ambient light.

Mechanical and electronic overload protection prevents damage to the knife drive. Shear bolts are conveniently located for easy accessibility and quick replacement.

Clamping pressure when actuating the clamp with the foot pedal is safe regardless of how the clamp pressure is pre-set for cutting.

Machine functions are continuously monitored with an electronic self check system.
