Quality is everything in a slitting operation. We have talked a lot about blades and material options in our ACE Better Business Blog, but there’s definitely more to achieving the perfect cut than those two things.
There’s no room for variations in the quality of the cut during the life of your blades. That means the last cut your blades make has to be as good as the first. There’s no opportunity to compromise. So what makes a difference between being able to ensure that are no variations in the quality of cut?
Of all of the factors to consider including the skill of your operator and your cutting environment, the quality of any slitting process is the one aspect of your operation that is most directly related to the ability to maintain consistent settings on every single knife holder on the slitting system. This is the only way to obtain the perfect cut.
When reviewing the pneumatic knife holder options available, Mario Cotta brand holders X-Series offer the best performance while simultaneously reducing machine downtime and safety risks. With a wide range of applications, the Mario Cotta X-Series provides the stability and cut stability operators expect from their slitting application so they can maximize profitability. Here’s a sampling of the standard operational and safety features for the Mario Cotta X-Series.
|
Double Shaft |
Two chromed steel shafts for knife descent that ensure absolute stability during slitting process. |
Increased stability allows a higher web speed without losing slitting quality.
|
|
Position Knob (X-35, X-50, X-75) |
Knife holder descent is regulated through a knob by two position valve: at rest (•), working mode(•) |
Effortless operation |
|
Single Air Inlet (X-35, X-50, X-75) |
Automatic Descent Side Load / Side Unload–Ascent Cycle |
Reduces set-up time |
|
Friction Free Approach (X-35, X-50, X-75)
|
Suitable for high precision slitting |
Low friction coefficient in the lateral movement and big size bearings grant reduction of the RunOut. The lower part is specifically engineered for superior stability and durability. |
|
Mechanical Lateral Plate (X-15) |
Knife holder lateral movement is centrally activated on the rail or bracket (manual mode). |
The harmonic steel plate provides a friction-free approach, with no jamming on holder’s hubs in its slim width. |
|
Cant Angle (X-15) |
Adjustable eccentric allows an onboard cant angle regulation |
No special tools needed
|
|
Easy to Remove Cartridge (X-15) |
Simply push the dedicated lever to remove the cartridge |
No special tools needed |
The X-Series also provides optional features that can be added on to increase operational efficiencies and operator safety. These include but are not limited to:
-
Score cut cartridges (crush and razor)
-
Full Guard
-
Oil Wick
-
Half Stoke Knob for those times when a full stroke isn’t desired
-
Graduated Nonius to display the diameter of the blade and allow a replicable and objective regulation of the knife penetration to maintain the most effective overlap or after changing or regrinding knives.
-
Cant Angle Versions – Fixed or Adjustable: the adjustable variant allows an onboard cant angle regulation without any special tools.
-
360° Knife Guard to increase the safety standards for operators during those production’s steps that present major risk to operators.
-
Cartridge Guard to increase operators’ safety during handling and knife changes.
-
Hard Cartridge with increased section of lateral force piston for heavy slitting
There's lots of information here and it's great information but how do you know which of the four Mario Cotta X-Series Pneumatic Knife Holders is right for your particular slitting operation?
We’ve put together a helpful chart that provides guidelines on which X-Series Pneumatic Knife Holder fits best based on the material you’re slitting and your desired outcomes. This information can steer you in the right direction but specifics should be discussed with a qualified project engineer and slitting operation expert to ensure you're getting the right option for your needs.
