Abstract: The invention relates to a method of monitoring the distance between the rolls of the roll pairs in a rolling line that includes a plurality of mutually sequential roll units where each unit includes a roll pair and a roller guide for leading a bar section or billet into said unit during a rolling operation. According to the method, the roller guides are provides with vibration measuring means for continuously sensing vibrations in the roller guides. These vibrations are analyzed with respect to frequency, for determining the distance between the rolls of the roll pair that immediately precedes or follows the roller guide.

Abstract: Arrangement for fastening a roll unit carrier (2) firmly to roll stand. The roll stand comprises a fastening device (15) which is journalled eccentrically in a rotatable cylindrical member (14) and has one end (16) provided with a fastening surface (16a) which in the fastening mode of the arrangement coacts with a complementary surface on the carrier (2). The arrangement includes elements (17, 18) for rotating the cylindrical member between a fastening position in which the carrier is pressed against the roll stand at a predetermined force, and a release position in which the carrier can be moved towards or away from the roll stand without being impeded by the fastening device.

Abstract: A roll-pair has synchronously driven shafts and a drive arrangement. The drive arrangement comprises an alternating current motor (12) and a planetary gear mechanism (13). The alternating current motor (12) and the planetary gear mechanism (13) are disposed in side-by-side relationship, the alternating current motor (12) having an output shaft and the planetary gear mechanism (13) having an input shaft. A transmission (14) connects the output shaft and the input shaft. The roll-pair and alternating current motor (12) and planetary gear mechanism (13) are all disposed on the same side of the transmission (14). The transmission (14) is a gear transmission. The input and output shafts are parallel to each other.

Abstract: The present invention relates to a method for grinding grooves in the peripheral surface of rollers roller guides for rolling mills. The roller (2) of a roller guide is caused to rotate while retained on its own bearing (8,9,10) as the peripheral groove is ground.The invention also relates to an apparatus for carrying out the method, and to a roller guide structure with which the method can be applied.

Abstract: An arrangement for removing an end-part from rapidly moving rolled material includes a cutting device (3) which functions to cut the moving rolled material, and a guide (4) which is located downstream of the cutting device. The guide has an active state, in which a forward end of rolled material (T) to be fed to the guide (4) in a first direction, is gripped and driven thereby and discharged therefrom in a second direction different from the first direction, and an inactive state, in which an end-part of rolled material (T) incoming in the first direction passes through the guide (4) without changing direction and without being gripped thereby. The arrangement also includes feed devices (5) which function to advance rolled material (T) in the second direction. This rolled material is discharged from the guide (4) in the second direction with the guide in its active state.

Abstract: A method for securing a roll-ring onto the end of a roll-axle, comprising prefitting a roll-ring onto a roll-ring mount, and securing the mount with the roll-ring fitted thereon, onto the end of a roll axle. Securement is effected by passing one single screw-threaded bolt axially through an opening through the roll-ring mount, and tightening the bolt into a screw-threaded recess within the end of the roll-axle. The mount has a cylindrical end part (22) on which a roll-ring (30) can be secured, and the mount has an abutment surface (24) against which a roll-ring is to be pressed. Clamping structure (27, 28) presses the roll-ring against the abutment surface, and projections and recesses (25, 29, 31, 34) non-rotatably secure the mount to an end of a roll-axle. The end of the roll-axle has a conical recess in which a conical external surface on the roll-ring mount shape-matingly fits.

Abstract: The present invention related to a wire-rod block which forms part of a wire rolling line and which includes two roll rings, between which the wire rod is rolled, and which further includes an input drive shaft and a gearing for transmitting the drive torque of the drive shaft to the roll rings. According to the invention, the input shaft (10) drives one of the roll ring shafts directly, via a first bevel gear (13) and also an output drive shaft (12), via a gear (11). The output drive shaft, in turn, drives the shaft of the other roll ring, via a second bevel gear (14), wherein the transmission ratios of the gear (11) and the bevel gears is such that the roll rings will rotate at mutually the same peripheral speeds.

Abstract: A wire rolling machine comprising a pair of parallel drive shafts, a housing mounted for swinging movement on each drive shaft, and a first gear within the housing secured to each drive shaft. A second gear within the housing is driven by the first gear, a driven shaft within the housing bearing at one end the second end and emerging from the housing and bearing at an end opposite the second gear a driven roll. Each driven roll has a peripheral groove, the peripheral grooves being adapted to be brought into registry with each other when the housings are swung toward each other. The driven shafts swing in a common plane. Structure is provided to swing the housings relative to each other about the drive shafts.

Abstract: The front and tail ends of fast travelling rolled goods (3) such as wire rod are cropped by leading the rolled goods into a guide groove (2) extending around the periphery of a circular disc (1). The disc rotates at the same peripheral speed as the linear speed of the rolled goods. The rolled goods are positively guided in this position and are caused to accompany the disc over a sector (24). The rolled goods are sheared by a cam-operated punch (8) carried by the disc, the punch moving parallel to the axis of the disc. The separated end pieces (22) of the rolled goods are lead away in one direction, and the cropped rolled goods (23) are lead away in another direction.
