Abstract: The invention relates to an improved method for lubricating transport systems or parts thereof, especially for lubricating guideways and rails in elongating systems. The inventive method can be realized in that the lubricant film continuity comprises the equation: X=(lubricating active time/lubricating inactive time)≧100 and/or the lubricant film continuity comprises the equation: Y=(lubricating active time/(lubricating active time+lubricating inactive time))≧10%.

Abstract: An improved apparatus for adapting speed, in particular for nippers (1) which can be made to travel along a rail arrangement (3), is distinguished by the following featuresa rotating and electrically conductive eddy-current body (17), preferably designed in the form of an eddy-current wheel or an eddy-current cylinder, is provided,the guide rail arrangement (3) runs at least over and away from a partial region of the eddy-current body (17) with a tangential component,on the carriages (1) which can be made to travel along the guide rail arrangement (3) there is provided or can be excited at least one magnet (7a, 7b), which is arranged on the side facing the eddy-current body (17) and, in the region of the eddy-current body (17), can be moved over and away from the eddy-current body (17), with an air gap being formed.

Abstract: An improved transport device comprises a novel guide rail (3). Carriages (5) can be moved along the guide rail (3), which carriages comprise guide elements (25a, 25b; 25c, 25d) for this purpose, which elements are supported on rail guiding surfaces (17a, 17b; 17c, 17d) of the guide rail (3). The guide rail is held in a prestressed and/or damped manner with variable guide elements (25a, 25b; 25c, 25d) comprising, for example, sliding pieces or running rollers at the respective spacing of the ?sic!. As a result, the spacing distance between the rail guiding surfaces (17a, 17b; 17c, 17d) can automatically be adjusted to the variable, in each case given, spacing of the guide elements (25a, 25b; 25c, 25d).

Abstract: An improved shock absorber device including first and second shock absorbers. The spring characteristics of the shock absorbers provide a jump function. The position and size of the differential force value in the region of the spring characteristics are such that, when propulsive and shock forces occur with a force value within the differential force value, the second shock absorber is not activated and the first shock absorber has already reached its maximum shock absorbing limit.

Abstract: An improved flat-sheet die, compared with the prior art, for an extrusion system for producing flat sheets has an extremely close succession of actuators (13), by way of which at least one die lip (3,5) is adjustable with a narrow-band bending line in order to define the outlet gap (1).
