Technical details and manufacturing context for Blade Holder

Definition
The blade holder is a critical component within a doctoring system that provides precise mounting, alignment, and secure clamping for the doctoring blade. It ensures the blade maintains consistent contact pressure and angle against the target surface (e.g., a roll or web) for effective scraping, coating control, or cleaning operations.
Working Principle
The holder typically uses mechanical clamping mechanisms (such as bolts, wedges, or pneumatic/hydraulic actuators) to fix the blade in place. It is designed to allow for micro-adjustments to control the blade's angle (doctor angle) and pressure against the surface, which are crucial for the doctoring process's effectiveness and to prevent damage to the blade or the substrate.
Common Materials
Stainless Steel, Aluminum Alloy, Carbon Steel
