Abstract

800,607. Doctors of paper-making machines &c. SCOTT, H. E. B. Nov. 15, 1956 [Jan. 13, 1956], No. 1288/56. Class 96. A doctor 11 of a paper-making machine has a spring 18 which presses the back of the blade 10 downwardly so that it contacts a lip 22 and a nose 19 of the blade-holder, both the lip 22 and the nose 19 extending substantially the whole length of the blade. The spring 18 may be in sections longitudinally; it may be arcuate or of rounded V-section and may be slotted transversely or diagonally. One or more rivets 24, or tongues pressed upwardly from the back of the blade 10 may aid in guiding it into position. The blade-holder may be in two sections screwed together at 15 and mounted on a bar (not shown in Fig. 2). The spring 18 may extend backwardly into a slot between the two sections. Specification 693,187 is referred to.
