摘要： PURPOSE:To prevent the oscillation of a cup-shaped grinding wheel by pressing the grinding wheel to a rotating body in such a manner as to come into contact with the surface of the rotating body within the range sandwiched by two parallel lines tangent with the inside diameter of the grinding wheel thereby grinding the rotating body. CONSTITUTION:The cup-shaped grinding wheel 3 is brought into contact with the surface of a work roll within the range H0 from the horizontal line X-X running the axial center of the grinding wheel up to the horizontal line C-G tangent with the inside diameter D1 of the grinding wheel. The wheel 3 is driven to rotate by the rotating force of the work roll, by which the work roll is ground in a non-driving system. The generation of a point of inflection by the wear, i.e., local inclination, is obviated on the cup surface of the grinding wheel and the cause for the generation of a clatter is eliminated by grinding the work roll in the above-mentioned manner.

摘要： PURPOSE:To grind uniformly a roll with a grinding device made into a simple construction by using just one grinding wheel for a piece of the roll, grinding the entire width of the roll and rolling over the grinding surface near the transverse central part of the roll. CONSTITUTION:The grinding wheel G is started from the point A at the body end of the work roll 1 and the roll 1 is ground toward the transverse central part S thereof. The axial center of rotation of the grinding wheel G is inclined inward by an angle thetawith the normal of the roll surface and one side of the cup surface of the grinding wheel is pressed to the roll surface, then the wheel G is rotated according to the rotation of the roll 1. The wheel G is detached from the roll surface when the wheel G arrives at the point B near the transverse central part S of the roll. The grinding wheel G is then retreated to the position B' and rolled over to the position C' where the angle theta of inclination of the axial center of rotation of the wheel G is inverted and again the grinding wheel is pressed to the roll surface as shown by C. The roll is ground toward the point D at the other roll body end. The wheel arrived at the point D is moved in the opposite direction and the roll is again ground to the point C. The wheel is retreated and rolled over at the point P and the roll is ground between B and A.

摘要： PURPOSE:To prevent the oscillation of a device by providing rotating resistors to a supporting shaft for a grinding wheel and housing the rotating resistors into a box body sealed therein with liquid. CONSTITUTION:The supporting shaft 4 for the grinding wheel 3 is extended and a gear 12 is fixed to the end thereof. The gear 12 is housed in the box body 13 sealed therein with liquid such as oil and is meshed respectively with the other gears 12a, 12b, 12c. The rotation of the gear 12 is transmitted to the gears 12a, 12b, 12c which rotate respectively in the liquid and play the role of the rotating resistors. The wheel 3 is driven to rotate and to grind the surface of a roll when the wheel 3 is pressed to the outside peripheral surface of the roll by actuating a hydraulic cylinder 7. The rotating gears 12, 12a-12c exert the resisting power to the rotation of the wheel 3. The clattering of the wheel 3 is thus eliminated and the oscillation of the device is prevented.

摘要： PURPOSE:To form easily and quickly a gear without dimensional errors and to reduce cost by heating locally the outside circumferential surface of an annular blank material to a prescribed temp., pressing a toothed punch thereto to deform plastically the blank material and performing said operation at an equal interval over the entire circumference of the blank material. CONSTITUTION:An annular blank material 1 is inserted and fixed to a mandrel 2 having a stopper 4. The outside circumferential surface of the ring is locally heated to a prescribed temp. in a high frequency furnace C and a toothed punch X is pressed thereto to deform plastically the material 1 to a tooth profile. Such operation is executed at an equal interval over the entire circumference of the blank material. Since the material is locally heated, the dimensional error over the entire part is decreased and the material is worked in a short time. The gear may be subjected again to hot punching or be finished by final cold punching in order to improve the accuracy of the tooth profile.

摘要： PURPOSE:To improve grinding efficiency by disposing a dressing tool to the non-contact part of a grinding wheel and rolling roll and pressing the tool to the side end face of the grinding wheel during grinding. CONSTITUTION:A supporting shaft 4 of the grinding wheel 3 is supported by a bearing box 5 and is pressed to the outside peripheral surface of a work roll 1 by the operation of a hydraulic cylinder 6. The dressing tool 10 is provided to the non-contact part of the wheel 3 and the roll 1 and is pressed to the bore part on the grinding surface of the wheel 3. The tool 10 is pressed always under the specified force to the wheel 3 by the operation of a hydraulic cylinder 11. The tool 10 follows up consequently the wear of the wheel 3 even if the wheel wears. The tool 10 removes successively the build-up part of the wheel 3. Since the build-up part which is the cause for the oscillation of the wheel 3 is removed, the stable grinding with the wheel 3 is made possible. The grinding efficiency is thus improved.

摘要： PURPOSE:To increase the operation rate by performing so that the strip sheet inserted between the outer peripheral face of a spool and a pressing plate is wound on a spool in the state of being pinched by the outer peripheral face of the spool and pressing plate according to the rotation of the spool. CONSTITUTION:A spool 12 starts its rotation and simultaneously a pressing roller 14 is displaced to the spool 12 side when a strip sheet is fed in and the tip thereof reaches close to the joining part 15 of the spool 12 and pressing plate 13. The strip sheet 11 is therefore pressed to the outer peripheral face of the spool 12 via the pressing plate 13 and in this state the strip sheet 11 and pressing plate 13 are wound onto the spool 12 with being overlapped. And when the strip sheet 11 is wound in several steps onto the spool 12, the pressing roller 14 retreats to the original position.

摘要： PROBLEM TO BE SOLVED: To assure high-speed and stable work by applying adhesives on tape- like elastic materials, such as waist bands of throw-away diapers, during the course of transporting these elastic materials and pressing the elastic materials to a moving web which is wound around a drum while holding the elastic materials stretched by utilizing a cam mechanism, thereby adhering the elastic materials to this web. SOLUTION: The plural band-shaped elastic members Ra to Rc are supplied by a vacuum attraction type conveyor 7 and are cut by a pair of cutting roll 1 and anvil roll 2 to the tape-like elastic members a to c of a prescribed width. The elastic members a to c are then transferred by a vacuum attraction type transfer roll 3 to an adhesive applying roll 4 and are coated 11 with the adhesives during the course thereof. Next, the elastic members a to c are supplied via a transfer roll 5 to a width expanding roll 6 and are vacuum attracted by plural pairs of chucks 16a,... at both ends thereof. The elastic members a to c are stretched in this state by the effect of a cylindrical cam. The elastic members a to c are then pressed to the prescribed positions of the web W carried by the vacuum drum 9 for web transportation, by which the elastic members are adhered and fixed to the web.
