    摘要: A magnetic tenter lever actuating device includes a coupling rail, preferably designed in the form of a pole shoe rail (21), by means of which the end of a tenter lever (3) can be pivoted deliberately from its open into its closed position and vice versa by means of a coupling region (29) formed at the end. An improved magnetic tenter lever actuating device is primarily characterized by the following features: the magnetic actuating device for the tenter lever further includes a safety device for actuating the tenter lever, the safety device comprises a mechanically acting redundant system for the forcible opening and/or closing of the tenter lever in the event of the failure or ineffectiveness of the magnetic actuating device, the safety device is arranged and designed such that, when an opening and/or closing movement is to be carried out by means of the safety device, the tenter lever can be pivoted mechanically, at least in its first opening pivoting range, out of its closed position or, at least in its final pivoting range, into its closed position.

    摘要: In prior art processes of this kind the actual thickness of the extrudate is measured, compared with a reference thickness and the setting regions of an extrusion plant are controlled dependent upon the degree of difference. In order nevertheless to improve the quality of the extrudate in relation to the desired reference thickness, according to the invention the evolution strategy process is used. An increase in the convergence rate can also be attained by taking into account strategy parameters which can be deterministically or stochastically changed, whereby mixing including fixedly settable strategy parameters is also possible. In particular, knowledge of the process can be involved as qualitative process partial knowledge.

    摘要: An improved transport device for a moving material web, in particular a stretching system for plastic film webs which is in particular suitable for high circulating speeds, is distinguished by the fact that a guide rail system (3) comprising at least one guide rail (3', 3") and along which tenter elements (1) can be moved by means of a linear motor drive (5), is integrally incorporated in the relevant linear motor (5', 5"). The respective tenter element (1) is supported with respect to the guide rail system (3) by means of a sliding bearing or a combined sliding and roller bearing.

    摘要: An improved transport device for a moving material web, in particular a stretching system for plastic film webs, comprises tenter elements (1) which can be moved along a guide rail system (3) on both sides of the material web (11). In this case, on both sides of the moving material web (11), a linear motor (5', 5") and a guide rail (3', 3") are provided, preferably in each case at least above and below the moving material web (11). The sequence of the guide rails located above, in relation to the linear motor, is opposite with respect to the moving material web, to the linear motors located below and the guide rail located below. In an alternative preferred embodiment, a maximum vertical and a maximum horizontal distance (a, b) are provided between a point of intersection (S) at the clamping point of the material web (11), which distance is selected such that the tenter mounting is stressed as little as possible.
