Magnetic tenter lever actuating device

Abstract

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.
