Abstract: PURPOSE:To obtain grip force and further high dimensional accuracy by forming in a predetermined pitch on the peripheral surface of a column or cylindrical body a helical or annular groove, providing orthogonally with it a linear groove and forming many fine protrusions. CONSTITUTION:A cylindrical body 11 is held between a pair of dies 16, 17 having in the inside many parallel protrusive streaks 15, and by sliding the one die 16, the cylindrical body 11 forces its peripheral surface to come into press contact with the protrusive streaks 15. And the cylindrical body forms in its peripheral surface by a predetermined pitch along the peripheral direction a helical or annular groove 14 and a helical or annular protrusive streak 18 therebetween. Next, a linear groove 19 is formed with a predetermined space in the axial direction for the groove 14 in the peripheral surface of the cylindrical body 11, and its peripheral surface forms many protrusions 21 arranged in a squared shape having a sharp angle. In this way, strong grip force is obtained while with very high dimensional accuracy.

IPC: B65H9/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To reduce external force so as to restrain the rotation fluctuation of a rotating member, the irregularity of the behavior of a recording paper, and the irregularity of the action of another member in contact with the recording paper by detecting the thickness of the recording paper, calculating a skew angle given to the recording paper based on the paper thickness data, and controlling a resist roll based on the calculated result. SOLUTION: The thickness of the recording paper 6 is detected by an optical reflection type paper thickness detecting sensor 9, and the paper thickness data are outputted to an arithmetically calculating part 17. The skew angle Δθis calculated based on the paper thickness data at the part 17. A control signal is outputted to driving circuits 16A to 16D based on the skew angle Δθso as to cause difference between the rotational speed of the resist roll 10A, (10B) and that of the resist roll 10C, (10D), so that the paper 6 obtains data obtained by adding and subtracting the skew angle Δθ to the skew angle data. Thus, since the paper 6 enters between each photoreceptor and a transfer roller at the skew angle, the external force given to each photoreceptor is reduced, so that the rotation fluctuation can be restrained.
