Abstract: The invention relates to a device for winding a strip material into a coil. The device comprises a winding mandrel (1) having a shaft element (2) and radially movable segments (16) mounted on the shaft element for winding and unwinding the strip material. The device further comprises an actuating drive (26) for spreading or collapsing the segments. The device also has a rotary drive (5) for rotationally driving the winding mandrel. To achieve a simpler and more economical design, a displacement device (60) is provided for axially displacing the actuating drive (26) together with the winding mandrel (1).

Abstract: The invention relates to a rolling plant (100) and to a method for its operation. Known rolling plants (100) typically comprise a reversing stand (110) for rolling a metal strip (200) in a plurality of rolling operations until the metal strip has reached the desired thickness. The reversing stand (110) is typically assigned at least one reversing reel device (130), which has a reel mandrel (132), for temporarily storing the metal strip (200) after individual rolling operations. The known rolling plants (100) also have a sensor device for determining the thickness of the metal strip.

Abstract: An expandable and contractible coiler mandrel for coiling metal strip, including: a rotatably supported coiler mandrel shaft with a wedge surface on its outer circumference; cooperating segments, which have an outer circumference with a coiling surface for the strip, and which have an opposing wedge surface cooperating with the wedge surface of the mandrel shaft in their end region facing away from the coiling surface; a mechanism for shifting the segments relative to an axial direction of the mandrel shaft; and a supply system for conveying lubricant to coiler mandrel regions that require lubrication. The supply system is connected with a lubricant pump having an actuating element for pumping, such that the pump is connected with the shifting mechanism or with the mandrel shaft, and the actuating element is connected with the other of the mandrel shaft or the shifting mechanism whereby pumping occurs only when the shifting mechanism is actuated.

Abstract: The invention relates to a rolling installation (100) and a method for its operation known rolling installations (100) typically include a reversing stand (110) for rolling a metal strip (200) in several steps until the metal strip reaches a desired thickness. The reversing stand (110) is usually associated with at least one reversing reel (130) with a reel mandrel (132) for an intermittent storage of the metal strip (200) after separate rolling steps. In addition, the known rolling installations (100) have a sensor device for determining the thickness of the metal strip (200).

Abstract: The invention concerns an expandable and contractible coiler mandrel (1), especially for coiling a metal strip, which has: a rotatably supported coiler mandrel shaft (2), which has at least one wedge surface (3) on its outer circumference; a number of cooperating segments (4), which have a coiling surface (5), especially for the metal strip, on their outer circumference, and which have at least one opposing wedge surface (7) that cooperates with the wedge surface (3) of the coiler mandrel shaft (2) in their end region (6) facing away from the coiling surface (5); means (8) for shifting the segments (4) relative to the axial direction (A) of the coiler mandrel shaft (2); and a supply system (9) with which a lubricant, especially lubricating grease, is conveyed to places (10) in the coiler mandrel (1) that require lubrication.

Abstract: For a directly driven coiler for winding rolled strip into coils, a piston/cylinder unit is proposed which can be supplied with pressure medium through rotary feeds arranged on a shaft extension or on a coiler shaft.

Abstract: An arrangement for axially displacing rolls in rolling mill stands. The rolls of the rolling mill stands are supported in roll supports or chocks which are adjustably and slidably guided in the roll housings of the stand. The rolls are displaceable by means of hydraulic piston-cylinder units which are supported relative to the roll housing and are connected to the supports of the bearings of the roll. The bearings of the rolls are axially slidable within the roll supports and a sliding guide is arranged on the roll support for a sliding carriage which supports a coupling device for a roll neck. The hydraulic piston-cylinder units are articulated to the sliding carriage. The coupling device includes drive members which are slidable in radial guides and can be placed in an annular groove of the roll neck. The coupling device is supported by the neck bushing of the deep-groove-type radial roller bearing which is immovably arranged in the sliding carriage.
