Doctor blade clamping assembly for a printing press

In a printing press having a chamber body positioned adjacent to a roll, a doctor blade clamping assembly comprising:

• spring means for applying a biasing force to a doctor blade so as to clamp the doctor blade to the chamber body, said spring means including a leaf spring, said leaf spring including a plurality of leaves assembled together in overlying relation to each other, and at least some of said leaves being of different lengths;
• securing means for securing the spring means to the chamber body in at least partial overlying relation to the doctor blade such that the spring means applies said biasing force to the doctor blade to clamp the doctor blade to the chamber body;
• and
• biasing means for biasing the spring means in a direction away from the doctor blade to release the doctor blade from said biasing force.

In a printing press having a chamber body positioned adjacent a roll, a doctor blade clamping assembly comprising:

• securing means for securing the spring means to the chamber body in at least partial overlying relation to the doctor blade such that the spring means applies said biasing force to the doctor blade to clamp the doctor blade to the chamber body, said securing means including at least one bolt extending partially through said leaf spring and secured to said chamber body;
• and
• biasing means for biasing the spring means in a direction away from the doctor blade to release the doctor blade from said biasing force.

In a printing press having a chamber body including a recessed area and positioned adjacent a roll, a doctor blade clamping assembly comprising:

• spring means for applying a biasing force to a doctor blade so as to clamp the doctor blade to the chamber body;
• securing means for securing the spring means to the chamber body in at least partial overlying relation to the doctor blade such that the spring means applies said biasing force to the doctor blade to clamp the doctor blade to the chamber body;
• and
• biasing means for biasing the spring means in a direction away from the doctor blade to release the doctor blade from said biasing force, said biasing means including inflatable bladder means positioned in said recessed area for biasing said spring means in a direction away from the doctor blade to release the doctor blade from said biasing force of said spring means.

In a printing press having a chamber body positioned adjacent a roll, a doctor blade clamping assembly comprising:

• spring means for applying a biasing force to a doctor blade so as to clamp the doctor blade to the chamber body;.
• securing means for securing the spring means to the chamber body in at least partial overlying relation to the doctor blade such that the spring means applies said biasing force to the doctor blade to clamp the doctor blade to the chamber body;
• biasing means for biasing the spring means in a direction away from the doctor blade to release the doctor blade from said biasing force;
• and
• stop means for limiting movement of said spring means in a direction away from the doctor blade, said stop means including a bolt extending partially through said spring means and secured to said chamber body.

In a printing press having a chamber body, a doctor blade clamping assembly comprising:

• a leaf spring;
• a securing assembly secured to the chamber body and engaging the spring to secure the spring to the chamber body in at least partial overlying relation to a doctor blade such that the spring applies a biasing force to the doctor blade to clamp the doctor blade to the chamber body and such that said spring is positioned entirely on a side of said doctor blade which is opposite to the chamber body so as to sandwich the doctor blade therebetween;
• and
• a biasing assembly positioned in a recessed area in the chamber body and which biases the spring to move the spring in a direction away from the doctor blade to release the doctor blade from said biasing force.

In a printing press having a chamber body, a doctor blade clamping assembly comprising:

• a spring;
• a securing assembly secured to the chamber body and engaging the spring to secure the spring to the chamber body in at least partial overlying relation to a doctor blade such that the spring applies a biasing force to the doctor blade to clamp the doctor blade to the chamber body;
• and
• a biasing assembly positioned in a recessed area in the chamber body and which biases the spring in a direction away from the doctor blade to release the doctor blade from said biasing force, said biasing assembly including an inflatable bladder positioned in said recessed area, said inflatable bladder at least indirectly engaging said spring when the bladder is inflated so as to bias said spring in a direction away from the doctor blade to release the doctor blade from said biasing force of said spring.

In a printing press having a chamber body, a doctor blade clamping assembly comprising:
