Lockout is the preferred method of isolating machines or equipment from energy sources. Your Conair product is equipped with the lockout device pictured below. To use the lockout device: Stop or turn off the equipment.
Different puller belt materials opti- mize performance with different types of extruded materials. The cutter portion utilizes a position-controlled servo motor. CSC units achieve park position repeatability less than 0.1 millisecond. Combination Puller/Cutter are available in several sizes:...

Cutting torque upgrades Several options can be used to increase the cutting torque: CSC 3 cutters can be upgraded from a 2.46 HP (MGE-455) to a 3.75 HP (MGE-490) servo motor. (The larger servo motor is standard on SCE-4, 5 cutters.) The standard aluminum cutter-head can be replaced with a heavier stainless steel one.

Cutter blade characteristics such as material, design, and UTTER LADE thickness can have a large effect on cut quality. ELECTION Blade materials Blue tempered spring steel is most commonly used because of its cost and availability over a wide range of thicknesses (0.010-0.062 inch).
Page 122
UTTER LADE Blade Design ELECTION Straight-edge knives have a straight cutting surface. A chop- ping action (which has cutting forces parallel to the cut) is typically obtained with straight-edge blades. Because the blade is mounted on a rotary arm, some slicing action (which has additional force vectors at various angles to the cutting edge) is obtained, but generally not through the entire cutting action.
Page 123
Blade thickness UTTER LADE ELECTION Because material is displaced rather than removed in rotary knife cutting, think of the blade as a wedge. The thicker the blade, the greater the displacement. This displacement can cause fracture in rigid profiles and tubing, which is often observed as a whitening on all or a portion of the cut.
Calculating Blade Interruption UTTER LADE Blade interruption ELECTION is the length of time which the blade interrupts the extrudate during the cutting process. Knowing blade interruption allows you to optimize blade speed and design for specific applications. You can calculate blade interruption for your application if you know: the cutting blade width blade speed (cutter rpm)
Page 125
UTTER LADE ELECTION To calculate interruption time: (0.937 in. + 0.250 in.) X 60,000msec/rev = 2.25msec 44.0 in. 718 rpm Knowing the interruption time and the line speed, you can cal- culate the amount of production deflection that must be accommodated during cutting.

Rotary knife cutter bushings are probably the most ignored BOUT aspect of cutting. Yet, they are probably the most important ingredient to obtaining clean, square, accurate cuts with mini- UTTER mal jamming and broken blades. USHINGS This appendix contains information about several aspects of cutter bushings: bore characteristics bushing length...

Supportive bushings become more important if heat is BOUT used to minimize whitening (fracturing). UTTER If you are cutting a square or rectangular profile, whether rigid or flexible, a round bushing bore will not offer USHINGS proper support and will often lead to an "S" shaped cut. A flat bottomed bushing will offer excellent support and enhance the shearing action of the blade.

Cutter bushing shear surface quality BOUT Similar to a dull pair of scissors, if the cutter bushing shear UTTER surface is not sharp the tube or profile is not supported to the side of the blade and the cut will not be clean. In some cases, USHINGS the entrance of the downstream cutter bushing is slightly radiused to minimize jamming.

Cutter bushing length BOUT CAUTION: Blade hazard UTTER In order to comply with OSHA regulations, the distance from the sidewall of the cutter to the USHINGS blade (through the bushing) must be long enough to prevent fingers from reaching the blade.
Page 131
Adjusting the cutter bushing gap BOUT UTTER If the bushing gap is too big, material is dragged down between the bushings creating a burr, especially with flexibles. USHINGS This may lead to jamming within the bushings where the upstream side of the cut extrudate actually hits against the downstream bushing surface.
Blade and bushing lubrication can nearly always improve the LADE AND quality of cutting. USHING Description of the cutting process UBRICATION Unlike sawing, a rotary knife cutter displaces material rather than removing it. When the knife blade first contacts the extrudate, it pushes it against the opposite side of the cutter bushings.
Page 133
If the blade has a rough surface where the extrudate rubs LADE AND against it, material will accumulate on the blade in a cheese grater fashion. This scratched material will also be passed USHING from the blade to the next cut and be seen as hairs or flakes. UBRICATION Some of the more flexible materials, such as silicones, soft urethanes and flexible PVCs, also exhibit drag against the...

The parameters are set either to the default setting, or to a setting specific to your requirements (Customer col- ONTROL umn). If you change any value, record it in this column. Keep these values up-to-date so you can easily restore your puller to ETTINGS normal operation if the memory is corrupted.

PID (Proportional, Integral, Differential) tuning is the process DVANCED of setting the control algorithm parameters (codes 65-69) to achieve optimum performance. While each puller is tuned ROCEDURE before shipment to optimize performance over the entire speed PID T range, customers may wish to tune the puller for their specific UNING operating conditions.
The digital belt gap sensor uses a linear scale attached to both SING THE belts to measure the relative distance between the belts. The relative distance is shown in thousandths of an inch (.001). IGITAL The sensor has five buttons: ENSOR On/Off - Turns the device on and off.
