Cylinder Punching Machine Plates & Heidelberg Cutting Jackets
Precision-Engineered Hardened Steel Counter Plates for Heidelberg, Johannisberg, Kama & Universal Cylinder Presses
ARK Industrie Cylinder Punching Machine Plates and Cutting Jackets are engineered to deliver stable, accurate, and consistent die-cutting results on cylinder presses. Manufactured from vacuum heat-treated high-grade alloy spring steel and precision-ground to micro-inch tolerances, these plates provide an ultra-durable, true-running counter surface across the entire cylinder circumference.
Engineered specifically to endure continuous high-speed converting cycles on Heidelberg KS, KSB, SB, SBB, SBD, as well as Kama, Johannisberg, and converted letterpress cylinders. Our plates eliminate partial cuts, prevent sheet distortion, protect cutting rules from premature pitting, and drastically shorten make-ready setup times for cartons, folding boxes, labels, and specialty corrugated packaging.

Why Packaging Converters Choose ARK Industrie Cylinder Plates
Engineered to solve the most common failure modes on cylinder die-cutters — plate deformation, high-spot scarring, uneven cut depth, and make-ready delays.
Cryogenic Vacuum Heat Treatment
Computer-controlled vacuum thermal treatment ensures homogeneous Rockwell hardness across the entire plate. Eliminates soft spots, brittle edges, and internal residual stresses that cause bowing under continuous rolling pressure.
Blanchard Micro-Ground Planarity
Precision rotary Blanchard surface grinding maintains a strict thickness tolerance within ±0.015 mm. Guarantees uniform knife-edge contact along the entire impression cylinder, eliminating the need for excessive patch-up and taping.
Anti-Scoring & Rule Protection
Precisely calibrated surface hardness (HRC 48–52 or HRC 56–60) prevents the steel die cutting rules from biting excessively into the plate. This protects expensive laser dies, extends rule sharpness, and prevents crease cracking.
Rapid Mount & Exact Fit Clamping
Finished with CNC-beveled leading and trailing clamp strips that drop seamlessly into the cylinder jacket lockup bar. Tight radial tensioning prevents slippage or lifting during high-speed production stops and starts.

ARK Industrie Cylinder Jackets vs. Conventional Soft Plates
Upgrading from untreated mild carbon plates to calibrated vacuum-hardened alloy cylinder jackets delivers measurable operational ROI.

Cylinder Punching Plate Mounting & Care Guidelines
Follow these engineering guidelines to ensure maximum jacket life, zero radial runout, and clean kiss-cut die cuts from the very first sheet:
Cylinder Drum Prep
Thoroughly clean the cylinder surface using an approved degreaser to remove paper dust, dried ink, or burrs.
Leading Clamp Insertion
Insert the beveled leading clamp bar firmly into the cylinder lockup channel, ensuring perfect parallel alignment.
Slow Inching Tension
Slowly inch the press while smoothing the jacket around the cylinder, then engage and torque the trailing lockup bar.
Kiss-Cut Calibration
Begin with minimal impression pressure and advance in 0.02 mm micro-steps to achieve a crisp cut without over-striking.
Frequently Asked Questions on Cylinder Punching Plates
Expert advice from our tooling engineers on cylinder jacket selection, Heidelberg conversions, and custom tolerances.
What information is needed to order a replacement Heidelberg cylinder cutting jacket?
To ensure 100% drop-in fitment, we require: (1) Press Model (e.g. KS, KSB, KSBA, KSD, SB, SBB, SBD), (2) Machine Serial Number, (3) Desired Nominal Jacket Thickness (standard 0.8 mm, 1.0 mm, or 1.2 mm), and (4) Clamp bar channel style (standard hooked clamp or flat bolted bar). If you have an existing sample or OEM drawing, our engineering desk can replicate it with micrometric precision.
How does jacket hardness affect die cutting rule lifespan?
If a plate is too soft (under 40 HRC), the cutting knife penetrates into the steel, quickly carving permanent grooves that cause rough edges and partial cuts on subsequent jobs. If a plate is excessively brittle (over 64 HRC), steel rules can chip rapidly. ARK Industrie calibrates plate metallurgy to HRC 48–52 or HRC 54–58, providing the ideal counter-surface that withstands millions of impressions while preserving cutting rule sharpness.
Can you manufacture cutting jackets for modified or converted letterpress cylinders?
Yes. Many packaging operations run converted Heidelberg, Kama, Albert, or Johannisberg letterpresses where the cylinder undercut has been modified. We specialize in custom radius machining, custom undercut compensations, and customized clamp bevels engineered specifically to your modified cylinder geometry.
What is the difference between a cylinder jacket and a flat platen punching plate?
A flat platen punching plate is a heavy, flat steel plate (typically 3mm to 8mm thick) used in platen die-cutting presses (such as Bobst, Brausse, or manual clam-shell platens) where the entire die strikes simultaneously. A cylinder jacket is a high-tensile, flexible spring-tempered plate that wraps around the rotating cylinder, where cutting occurs progressively along a line of tangential contact.
How are ARK Industrie cylinder plates packaged for damage-free transit?
Because cylinder jackets are precision ground and pre-curved, improper packing can distort planarity. Every jacket is thoroughly coated with rust-inhibiting protective oil, vapor-barrier wrapped, clamped to rigid wooden contour cradles, and shipped in heavy-duty export-grade wooden cases to ensure arrival in pristine, ready-to-mount condition.
