Abstract
Doctor blade apparatus having a mounting plate rigidly holding the blade. The doctor blade mounting plate is independently slidably and pivotably mounted by a ball-bearing on each of a plurality of spaced support ports and resiliently supported thereon by compression springs. The apparatus allows movement of the mounting plate and the blade carried thereby in several degrees of freedom with adjustment means providing independent adjustment at each of the supporting posts.
Claims17
Apparatus for supporting a doctor blade in position against the surface of a roller having an axis of rotation, comprising:
- (a) mounting means for firmly holding a doctor blade;
- (b) a base;
- (c) support means for supporting said mounting means on said base including a plurality of posts mounted to and extending from said base in an elevational direction, said support means engaging said mounting means so as to permit linear elevational motion of said mounting means on said posts and rotational motion thereof around a longitudinal axis parallel to the axis of rotation of the roller and around a lateral axis through said mounting means, said support means preventing linear motion of said mounting means along the lateral and longitudinal axes and rotational motion around an elevational axis parallel to said posts;
- and
- (d) means for resiliently urging said mounting means back to an initial position when displaced from such initial position in any motion permitted by said support means.
Doctor blade apparatus for supporting a doctor blade in position against the surface of a roller having an axis of rotation, comprising:
- (a) a base;
- (b) a plurality of posts affixed to and extending from said base;
- (c) a mounting plate having a plurality of holes therein in position to align with and receive said posts;
- (d) attaching means for firmly attaching a doctor blade to said mounting plate;
- (e) bearing means, mounted to said plate in each of said holes in said plate, for receiving and engaging said posts to allow said plate to move along each individual post toward and away from said base in elevational movement and to allow rotational movement of said plate around a longitudinal axis parallel to the axis of rotation of the roller and around a lateral axis through said plate, while engaging said posts to substantially prevent linear movement of said plate along the lateral and longitudinal axes and rotational motion around an elevational axis parallel to said posts;
- (f) a plurality of lower support springs each mounted at one of said posts between said base and said plate to provide support for said plate;
- (g) a plurality of upper support springs each mounted at one of said posts above said mounting plate;
- and
- (h) adjustment means engaged to each of said posts for adjustable upward and downward positioning thereon in engagement with said upper spring, whereby adjustment of the position of said adjustment means at each of said posts determines the elevational position of said mounting plate above said base at each said post.
