The invention relates to a measuring device, a roll stand and a method for detecting the height of a roll gap between two working rolls in the roll stand. In order to ensure a high level of measurement accuracy of the roll gap transmitter even in the case of horizontal displacement of the working rolls in or against the rolling direction it is proposed in accordance with the invention to carry out adjusting the movement of the roll gap transmitter (110) with respect to the working rolls in the case of a displacement in or against the rolling direction so that even in a new or displaced end position of the working rolls a suitable relative position, which is required for a high level of measurement accuracy, between roll gap transmitter and the working rolls is guaranteed.

The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.

摘要:
The high pressure pump comprises a drive shaft (12) with at least one cam (16) or eccentric and at least one pump element (18) with a pump piston (20), driven in the reciprocating direction by the cam (16) or eccentric on the driveshaft (12) in a reciprocating motion. A support element (44) is arranged between the pump piston (20) and the cam (16) or eccentric on the driveshaft (12) and also a roller (46) running on the cam (16) or eccentric is mounted to rotate therein. A support (60) for the roller (46) in the direction of rotation is arranged adjacent to the same in the direction of the rotational axis (47) of the roller (46). The roller (46) and/or the support (60) comprises a surface with high wear resistance at least in the contact region between the roller (46) and the support (60).

A high-pressure pump having a rotationally driven drive shaft with a shaft portion embodied eccentrically to its axis of rotation, on which shaft portion a ring is rotatably supported. At least one pump element, has a pump piston, driven at least indirectly in a reciprocating motion by the drive shaft via the ring and resting at least indirectly on the ring. The ring is provided, at least on its outer face facing away from the shaft portion, with a coating of a friction-reducing paint in at least one region, in which the at least one pump piston rests at least indirectly on the ring.

A hot-vulcanizable, pumpable rubber-based adhesive/sealant where the rubber component is a mixture of butadiene solid rubber and butadiene or isoprene liquid rubber, and wherein the liquid rubber comprises carboxylic acid groups. The adhesive/sealant compositions of the invention are particularly useful for bonding metal sheeting in the construction of automobile shells.

A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.
