Circular blades are configured around the cutting material, machine interface and required edge. MEIRENTE can work from an approved drawing or a sample when a standard flat or dish-shaped blade is not an exact fit.
Flat, dish-shaped and other circular knives are used across film, foil, paper, paper-core, tape, rubber, nonwoven and converting operations. Machine layout and cutting method determine whether the blade runs against a mating knife, an anvil, a holder or another supported cutting system.
Material grade, hardness and bevel should be reviewed together with speed, abrasive content, cut cleanliness and the risk of chipping. A harder blade is not automatically the better choice when the installation, impact load or mating condition requires additional toughness.
For a non-standard circular blade, the approved drawing controls diameter, bore, thickness, runout-related features, holes, keyways, dish direction and edge geometry. A sample can support identification, but critical dimensions should still be confirmed before repeat production.
For a custom review, send the drawing or sample dimensions together with the machine and application details you already have. Final specifications are confirmed before production.
Direct answers for blade buyers
Circular blades are configured around the cutting material, machine interface and required edge. MEIRENTE can work from an approved drawing or a sample when a standard flat or dish-shaped blade is not an exact fit.
Confirm outside diameter, bore, thickness and dish or flat profile; keyways, mounting holes and other locating features; cutting material, operating condition and current blade problem. Include the required quantity and any current cutting defect when available.
MEIRENTE reviews non-standard industrial knife requests from an approved drawing or sample. Final dimensions, mounting features, material, hardness and edge geometry are confirmed before production.

Blade selection by application
Compare circular slitting blade applications by web material, converting process and required edge result before confirming diameter, bore, thickness, bevel and machine fit.
Thin plastic films and technical membranes require stable web tension, low edge disturbance and blade geometry suited to the film structure.
Adhesive transfer, liner behavior and roll buildup must be considered when selecting blades for tape, labels and laminated converting webs.
Paper, tissue and nonwoven rolls need clean edges with controlled dust, fiber pull and width consistency across the finished reel.
Abrasive paper, cloth and belt stock combine hard particles with flexible backings, requiring stable support and wear control without tearing or shedding the coated edge.
Cable wraps, shielding laminates and electrical insulation webs need narrow-width control while limiting burr, layer separation and damage to functional coatings.
Soft nonwoven and laminated hygiene materials require controlled web tension, low lint generation and consistent edge quality at production-line speed.
