2.3. Construction of the machine

Th e cutter consists of three main mechanisms: knife, clamp and backgauge

drives and other additional devices.

2.3.1. Knife driving mechanism

Drawing 4. Kinematic diagram of the knife driving mechanism

The driving mechanism for the knife is shown on Drawing 4. Hydraulic double – acting

cylinder (actuator) 1 is fixed on the knuckle 2. Piston rod 3 is connected with the levers

4, which are connected with connecting rod 5, which pull knife beam 6 together with the

The knife bar 6 moves between the slide ways 7 and 8, in perpendicular plane to the

Text on page 8

work tables plane. Inclination of the slide ways at different angles allows inclination of

the knife bottom edge at the same angle, when the knife moves down. It decreases a

force required for cutting, and the cutting accuracy is increased.

The knife is so guided that in its bottom position the blade is parallel to the under knife

cutting stick, and penetrates it up to 0,5 mm depth. Admission of the cylinder with the

entry V1 causes, the piston rod 3 moves through the lever 4 knife beam and goes

down. After cutting down material, admission of the cylinder with the entry V2 causes

piston rod 3 to go back and the knife beam goes up and stops in the top position.

2.3.2 Clamp bar mechanism

Drawing 5. Kinematic diagram for the clamping bar drive mechanism

The driving mechanism for the clamping bar is shown on Drawing 5. Hydraulic double

  • acting cylinder (actuator) 1 through the levers 2, pulls clamping beam 3 down.

Clamping beam 3 is shifted in the slideways (not stated on the drawing) , that

guarantees its parallelism to the cutting line.

Lowering down the clamp bar 3 is possible also by pressing foot pedal 4. Pushing the

pedal 4 moves the bar 5 into the lower position. Return of the clamping bar 3 is

permitted by the spring 5. Spring 6 causes the return of cylinder 1 into its start position.

2.3.3 Back gauge mechanism

Drawing 6. Kinematic diagram for backgauge mechanism.

Electric motor 1 drives the feed screw through the belt transmission 2, through the

nut forcing the movement of the base motion 8 .

The base 8, bolted together with the backgauge bar 4, is guided on the guiding shaft 7.

The limit switches 9, 10 cause the backgauge bar 4 to stop in its extreme positions.

An accurate setting of the backgauge bar enables knob 5. The pulse- rotary converter

7.3. Regeneration of knife

Quality and accuracy of the cutting depends totally on the knife sharpness and the correct choice of the cutting edge angle.

7.3.1. The features of the blunt knife:

rough and uneven plane of stack to be cut;

edges seizing of material to be cut;

increased accumulation of the paper dust;

7.3.2. Grinding conditions of the cutter knife:

  • grinding machine of correct operation;
  • appropriate chosen grinding wheel
  • clean and sharp grinding wheel /”sparked out”/
  • correct chosen grinding parameters
  • even fixing of the knife

The manufacturer of knives used in the cutter recommend the cup-type grinding wheel or

grinding segments, “J” hardness, 60-80 grain size, with keeping:

  • 500 m/min grinding peripheral speed;
  • 8-10 m/min traveling speed;
  • max. Grinding Wheel stroke per 1 feed: 0,005 mm;
  • cooling with water-oil emulsion, 60 l/min., at least;

The correct sharpen knife is shown on drawing 39.

7.3.3. Selection of the grinding angle

Depending on the cut down material, a ground off angles are between 16 o and 26 o .

Soft material needs a smaller grinding angle, whereas a hard material, a larger grinding

If the cut materials are of different hardness, then a larger grinding angle is favourable

Quick start

  1. Install the side tables and level the cutter by adjusting the foot.
  2. Connect to a 5-wire L1, L2, L3, N, PE supply on a 30A protected circuit.
  3. Turn the main switch on and press the green "I" button; a green light confirms the light barrier is clear.
  4. Set the backgauge with the program module, or press in and turn the crank for fine tuning.
  5. Set clamp pressure with the knob (left to reduce, right to increase) to suit pile height, size and paper.
  6. Press and hold both cut buttons until the cut is complete. Use the foot pedal to clamp without cutting.

Frequently asked questions

What is the maximum pile height?

100 mm without the false clamp, or 96 mm with the false clamp fitted. See page 36.

How often should the hydraulic oil be changed?

The hydraulic unit maker recommends changing the oil after one year of intensive work. Drain it while warm and use HL 46 hydraulic oil. See page 43.

How often should the knife be changed?

About every 8 hours of effective cutting, based on experience. See page 21.

How often does the cutter need lubrication?

The lubrication points should be greased every week, with the machine switched off, using non-liquid grease. See page 38.

Can I adjust the hydraulic pressure?

The overflow valve is factory set to 170 bar and sealed. Only an approved service technician should change it, or the warranty may be lost. See page 43.
