Title: Sheet treating device
Inventor: NAKANE NAOHIRO
IPC: B65H15/00
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To eliminate a jarring sound generated when recording material collides with a guide member of a path. SOLUTION: A path P1 is a reversing path curved in U-shape. Recording material S moving in this path P1 is bent to generate bonding reaction. The rear end of the recording material S moving in the path P1 therefore collides with a guide member 118-2 because of bending reaction and generates a jarring sound. A plate spring 120 serving as a means for absorbing the bending reaction of the recording material S is therefore installed at an inlet part of the path P1. The plate spring 120 energizes the recording material S moving in the path P1, in a bending direction in a position shown by a continuous line.

Title: Bending process of metal pipe
Inventor: HANAMOTO YUKIMITSU
IPC: B21D7/16
Filed: 1979-04-26
Abstract: PURPOSE: To prevent occurrence of reduction of thickness and flattening phenomenon of metal pipe on the outside of bending, by cooling the band region of a proper width at the both sides in the circumferential direction spaced at an appropriate distance from the outermost side position of the bending part of metal pipe when heating.  
     CONSTITUTION: A metal pipe 1 is passed between guide rolls 2, 2 and 3, 3, and is locally heated in ring form by means of high frequency inductor 4. While buckling and holding the bend end part of the part 1 with a clamp 6, the pipe 1 after heating is cooled in the specified parts as described below, and a bending moment is given to the pipe by rotary guide of an arm 5 to bend while continuously deforming plastically. That is, vicinities A, A of parts spaced by distance (a) from the vertical axis at the bending outside T of the pipe 1 when heating are cooled. Therefore, the length of A-A on the outside T becomes tension region, while the length of A-A in the bending inside C becomes compressive region. The tensile strength of cooled band regions A, A is set extremely larger than in the other regions. As a result of this, reduction of the thickness on the outside T may be prevented, and also flattening may be also avoided because component of force in the vector direction may work in band regions A, A.

Abstract: PURPOSE:To have sure identification as well as prevent such troubles as errone ous suction, jamming, etc. by installing a tension roller to pinch the center of sheets with a transport belt, and by installing a plurality of correction rollers on the transporting direction side of said tension roller in an arrangement sym metrical about the center line and in the form of a circular arc. CONSTITUTION:Each banknote 2 fed while pinched by a transport belt 1 and a belt 13 intrudes between a tension roller 7 and said belt 1 in such a condition as given a habit of folding, and then between the belt 1 and correction rollers 9, 10 and a center restriction roller 11. Because these correction rollers 9, 10 are arranged with an opening angle theta and theta, respectively, a sideways feeding force with K1tantheta1, K2tantheta2 is applied to each banknote 2 with such folding habit by the rollers 9, 10 with respect to the feed amount P of belt 1. This feeding force corrects the folding habit as the banknote 2 goes farther from the abovementioned roller 7, and the banknote 2 is set between the belts 1 and 18 in tensed condition to be then transported in the direction as shown by arrow. This correction of folding habit provides sure identification of banknote about its sort and pattern through accurate sensing of its width.
