摘要： PURPOSE:To perfectly automate coiling work by pressing and sticking a double coated adhesive tape on a leader tape to the tip part of spacer paper and winding an spacer paper by pressing the adhesive tape on a winding shaft for spacer paper. CONSTITUTION:The strip 2 of a coil 1 is uncoiled with pinch rolls 16. At this time, the spacer paper 3 is separated from the strip 2 and hung down. When the tip of the spacer paper 3 is detected with a detector 7, a pay-off reel 15 is reversed and the tip of the spacer paper 3 is made so as to come to on the extension line of a cylinder 10 for a press roll 9. The tip position of the adhesive tape 4 which is stuck on the leader tape 5 is detected with a detector 8 and stored. The cylinders 10, 12 are operated after positioning and the press rolls 9, 11 are pressed against the pay-off reel 15 and a winder 6 for spacer paper and the second half part of the adhesive tape 4 is stuck on the spacer paper 3. The first half part of the adhesive tape 4 is stuck to the winder 6 by revolving the pay-off reel 15 forward and the press rolls 9, 11 are separated and the spacer paper 3 is wound with the winder 6.

摘要： PURPOSE:To surely drain a strip with a compact device by sucking and removing water on the surface of the strip through perforated concentric outer ring rolls by use of a strong sucking force generated in a fixed shaft having a negative pressure sucking hollow hole. CONSTITUTION:The axis of fixed shafts 1 extends in the width direction of a strip 7, the shafts 1 are provided with a sucking hollow hole 2 extending in the axial direction and a slot communicating with the hole 2 and opening to the side contacting with the strip 7. The shafts 1 are also provided with an concentric outer ring roll 5 on the periphery of the shafts 1 to hold the top and bottom surfaces of the strip 7. Many through holes 1a are bored in the entire of a necessary surface of the rolls 5. When the holes 2 are brought to be a negative pressure by sucking, water, etc. on the surface of the strip 7 are sucked into a sucking device through holes 1a, slots, holes 2, and hoses 10.

摘要： PURPOSE:To improve the productivity by obtaining a good plate shape, by setting the crown pattern and quantity of a backup roll according to the rolling plate width and by adjusting the amplitude according to the shape and the output of a load detector while under rolling. CONSTITUTION:The backup roll 3 of a cluster rolling mill is divided into plural rolls and the crown pattern and crown quantity are provided with their setting possibly. Prior to rolling, the roll 3 is initially set to the prescribed calculation value via an adjusting servo device 7 by calculating the crown pattern and quantity by inputting a plate width information 12 and estimated rolling load 13 to a preset arithmetic unit 10. While under rolling, the crown of the roll 3 is adjusted by outputting to the servo device 7 by calculating the crown quantity only by inputting the outputs of a load cell 8 and plate-like detector 9 to a feedback arithmetic unit 11. A good plate shape is therefore made and the productivity can be improved.

摘要： PURPOSE:To normally coil a set-off sheet by sending a thin strip to the upper side of an opener and then bringing the end of the opener into contact with the lower surface of the thin strip to peel the set-off sheet in a payoff of a metal thin strip coil in which the set-off paper is inserted. CONSTITUTION:After the end of the base sheet 3 is lead out on the upper side of the opener 6, the end of the opener 6 is held up and brought into contact with the lower surface of the base sheet 3. When a coil 2 is driven under such a state, though the set-off sheet 4 sticks to the lead-out base sheet 3, it receives a shearing force, is peeled from the base sheet 3 and falls under the opener 6. Then, if the coil 2 is driven for rotation, the end of the set-off sheet 4 is sent out to the lower side of the opener 6. Thus, the guard sheet can be sent out normally.

摘要： PURPOSE:To reduce the manufacturing cost of the title roll and to quicken roll exchange by coupling the split reinforced roll to a roll supporting shaft supported freely turnably to a reinforced roll frame through an eccentric section. CONSTITUTION:The roll supporting shaft 1 is supported freely turnably to the reinforced roll frame 3. Eccentric bushes 5a, 5b, 5c having different eccentricities respectively are provided on the fitting parts of plural split reinforced rolls of supporting shaft 1 right and left symmetrically with respect to the central part in the shaft center direction of the supporting shaft 1. The split reinforced rolls 23a, 23b, 23c are coupled with these bushes. By this method, the manufacturing cost of the split reinforced rolls are reduced and the exchange of rolls is quickened.

摘要： PURPOSE:To enable rolling of a strip having a short width without damaging roll surfaces by putting part of back up rolls of intermediate rolls to support work rolls into a non-contact state according to the transverse length of the strip to be rolled. CONSTITUTION:A pair of the upper and lower work rolls 6, 6 which roll the strip 4 by holding the same in place between the rolls are pressed and supported by the back up rolls 10 via the intermediate rolls 8 provided on at least one side thereof. The back up rolls 10 of a cluster type rolling mill 2 constituted in the above-mentioned manner are constituted of supporting rolls 12 supported to chocks 11 and the rolls which are axially divided to the plural rolls; a center roll 10a, quarter roll 10b and end roll loc supported respectively freely turnably by means of bushings 14, small exccentric bushings 16 and large eccentric bushings 18 on said shafts. The strip 4 is rolled while the end roll 10c, etc., which are a part of the rolls 10 are held detached from the intermediate rolls 8 and are held in the non-contact state, if the transverse length of the strip 4 to be rolled is shorter than the barrel length of the work rolls 6.

摘要： PURPOSE:To magnify the applicability of an automatically inserting device for set-off sheet by adopting a belt wrapper which is brought into contact with the outer periphery of the lower half of a thin strip take-up reel and circulates endlessly in accordance with the peripheral speed. CONSTITUTION:When the tip of a steel sheet 1 is coiled round the take-up reel 3, the hanging set-off sheet 11 is caught between a belt 6 and the take-up reel 3, makes about half a round along the outer periphery of the lower side of the take-up reel 3, then, comes out on the left side of the take-up reel, separates from the belt 6 there and is caught between the rear side of the steel sheet 1 entering the take-up reel 3 from the left and the steel sheet 1 on the surface of the take-up reel 3. Consequently, even when the steel sheet 1 is caught from the upper surface of the take-up reel 3 so that it crosses the upper part of the take-up reel 3, no non-conformity is generated, the applicability of the automatically inserting device for guard sheet can be magnified and the cost of the device can be reduced.

摘要： PURPOSE:To simplify a mechanism for adjusting roll crowns by setting the eccentric centers of eccentric bushings for supporting the respective rolls of a pair of split back up rolls asymmetrically with the centers of supporting shafts and turning the eccentric bushings in the same direction, thereby moving the respective rolls upward or downward. CONSTITUTION:Driving levers 26b, 26c are turned to turn the eccentric bushing 16b or 16c by a prescribed angle with a lever 24. Quarter rolls 6b and side rolls 6c are respectively moved upward or downward to form a desired crown pattern in the axial direction of the roll together with the center roll 6a fixed at the center. A frame 36 is then moved in a vertical direction and the work roll 2 is pressed via an intermediate roll 4, by which the roll crown thereof is adjusted.

摘要： PURPOSE:To completely automate a coiling operation by detecting the position of a set-off paper with a paper detector and touching and detaching the set-off paper through a coiling axis coated with adhesive in a set-off paper coiling device of a strip coil. CONSTITUTION:The strip coil 1 uncoiled by a low speed rotation is divided by an opener 11 into a strip 4 and a set-off paper 5. The divided and hung set-off paper is detected automatically by a paper detector 17, a paper sleeve 6 is pressed by the information to the hung set-off paper 5, after the set-off paper 5 is stuck to the paper sleeve 6 by the pressure sensitive adhesive double coated tape stuck previously on the paper sleeve 6, the paper sleeve returns to the prescribed position and coils the set-off paper. In this way, the coiling operation of the set-off paper 5 requires no manual work and is automated completely.
