Label Slitter Support
Rewinder Support Answers
Use split-ring lockwashers to increase the effective diameter of the vanes and make the cores fit more tightly.
Remove one of the vanes and place a #8 split-ring lockwasher on each screw BETWEEN the Shaft and the vane. Retighten the screws. If needed, washers can also be added under a second and if desired, the third vane. On 10″ shaft Models be sure to add lockwashers evenly under the inner and outer set of vanes.
2. Cores are slipping on my Adjustable Core Holder (ACH)
The secret to having the label cores fit tightly on the ACH is to slide the core ONLY PARTWAY onto the 3 fingers of the ACH. Now adjust the diameter and lock the 3 lock levers. Then slide the core the rest of the way onto the ACH up against the Flange. A little experimentation will show you just how far to slide the core onto the fingers before locking the adjustment.
If you are trying to use the ACH with multiple cores for slitting you will probably want to use one of LABELMATE’s “Quick-Chuck”™ Quick Locking Core Chucks instead. These Chucks will firmly lock all the cores equally giving you superb results. “Quick-Chucks” are available for core diameters of 38mm, 40mm, 44mm, 50mm, 70mm, 76mm or 100mm. Need other core diameters? Ask us about availability.
3. How do I reverse the direction of my MINI-CAT-10 or MC-11 Rewinder? (If there is no direction switch at the back)
Easy. Unplug the Power Connector from the Power Input Jack on the rear of the MC-10 or MC-11 Rewinder. Pull the little Connector (may be elbow shaped or straight) off the end of the Power Cord and reverse the Connector 180° so either the (+) or the (-) sign is aligned with the word (TIP) imprinted on the mating Connector. Plug the Power Connector back into your Rewinder.
4. My Rewinder is plugged in. Why won’t it work?
Make sure the ON-OFF switch rocker on the rear of the unit is in the “ON” position so the red indicator stripe is showing.
On the MC-10 or MC-11 Rewinder, make sure the VOLT CHANGE Switch on the AC/DC Power Adaptor is set to “3” or more. The “1.5” setting is used only when using the MC-10 or MC-11 as an Unwinder.
On the CAT-3 or CAT-40G Rewinder, make sure the “« 0 »” Direction Switch is in either the “«” or “»” position and that the “TORQUE” Control is advanced to at least mid-position. The center (“0”) position is OFF. Once the Rewinder is operating, adjust the “TORQUE” Control as desired for proper rewinding. See also Question 5 immediately below.
5. My Rewinder is pulling too hard (or not hard enough)
On the CAT-3 Rewinder, rotate the “TORQUE” Control as desired. The “REWIND/SLIT” Switch provides a Low and High Torque Range for a wide range of available torque.
On the MC-10 or MC-11 Rewinder, the torque adjustment is made by the slide switch setting on the AC/DC Adapter plugged into the wall outlet. Make sure the VOLT CHANGE Switch on the AC/DC Adaptor is set to “3” or more for rewinding. A higher setting provides more torque while a lower setting provides less. The “1.5” setting is used only when using the MC-10 or MC-11 as an Unwinder.
Slitter Support Answers
1. My Slitter is not slitting properly
There are a few things to check. First, make sure that the tip of the cutting blade is extended well past the round white Fixed Paper Guide. If you attempt to slit using the very tip of the blade it will not work. You want the cutting to be taking place along the length of the blade not with the point.
Next, make sure the red blade Pressure Bar is contacting all Blade Holders evenly. If it is not, loosen the attachment screws at the Slitter Chassis and reposition the Bar and retighten the screws.
Of course, you must have SHARP Blades. While ordinary snap-knife blades can be used, the quality of blades you can buy at the local hardware store varies tremendously. LABELMATE now supplies only special ground steel, premium blades made in Germany, renowned for fine cutting instruments. These blades are recommended as they yield the best results and last much longer than ordinary blades. The blades are available from LABELMATE in a convenient 10-blade dispenser pack. Order Model HSB-10.
If you attempt to cut only a web / release liner with no labels on it, you will probably not have good results. The Slitters depend on the added stiffness of the label web that has labels on it to provide a good cut.
In every case, you can expect better results doing your slitting “off-line,” using an Unwinder, Slitter, and Rewinder as a dedicated slitting station. In “in-line” use, at the output of a printer, the set-up may be difficult as you try to attach the multiple slit webs to the rewind cores AND get your printer going too. Also, most printers do not have a smooth continuous output, but rather are starting and stopping constantly. This means the slitting operation will be always starting and stopping. The static (starting) friction / resistance to cutting is always much higher than the dynamic (running) friction / resistance. This may contribute to jerky and unpredictable slitting results. Further, as the number of blades increases, the required rewind force increases, eventually reaching the point where too much force is being put on the labels coming out of the printer. This can result in the labels being pulled out of registration or other undesirable results. See also the Answer 2. immediately below.
2. How do I slit using a lot of blades?
The number of blades you can use at one time is a practical matter. The minimum label width is about 12mm. You need to request special small head lock screws to do this. With standard BH-1 Blade Holder Lock Screws the minimum slitting width is about about 18mm.
The difficulty with a large number of blades is starting the slit webs onto the rewind cores and getting them taped in place with equal tension. It is usually much more convenient and productive to do slitting of 6- or more “up” labels in two passes. You might do a single slit as the labels come out of the printer. This almost always works well. Then, move to your “off-line” slitting station and do the second pass with two blades. This will be easy to set up and you will probably find your overall throughput is much greater than trying to do the entire slitting job at one time “on-line.”
A complete off-line Slitting Station will always give better results than trying to slit in-line at the output of the printer. Please see the question immediately above for more information SLITTING Q.1 . Please feel free to call and talk with one of our technicians about your particular slitting needs.
