Abstract: PURPOSE: To obtain a mechanized liquid absorption measuring instrument by providing a grasping device, a balance, a humidifying device composed of a metallic cylinder and paper, and a blotting device having upper and lower cardboards surrounding a sample and a blotting roller at continuous working positions. CONSTITUTION: At a position I, the negative-pressure grasper 4 of the instrument 1 for measuring liquid absorption of paper takes out a paper sample 3 and, at a second position II, the grasper 4 puts the sample 3 on the edge of a pipe 5 having a hole 6. At a third position III, the grasper 7 of the rotating plate 8 of the instrument 1 places the sample 3 on the plate 15 of an electronic balance 9 together with the grasper 4. After measured values are stored, the grasper 7 carries the sample 3 to a fourth position IV. A working cylinder 19 brings the plate 15 into close contact with a swingable metallic cylinder 10, pours water in the cylinder 10 in a container 7, brings the water into contact with the sample 3. A driving device 11 discharges the water by swinging the container 17 and an arm 13. On a table, the sample 3 is put between blotting papers 23 and 28 stretched between rolls and, after a blotting process, the sample 3 is sent to a table 37 and taken out and carried to a balance by means of the grasper 7. The liquid absorption of the sample 3 is measured from the preceding and succeeding measured values. When this constitution is used, the measurement can be mechanized fully.
