Abstract: A continuous paper web is severed transversely in between the transportation cycles at the paper's maximum allowable rate of feed. The transverse cutter device has a stationary bottom blade 6 and a driven upper blade 5 fixed to or integral with a permanent magnet 7a, and a linear motor is used as the drive for the upper blade. The motor stator 7c is fastened to a carrier 4, and the driven blade undergoes reciprocating or vibratory strokes within a stator slot.

Abstract: For the better identification of not-enrolled fingerprint images, images of skin lines of two juxtaposed fingers (1, 2) of a hand are recorded. The orientations of the finger longitudinal axes (L1, L2) with respect to the normal direction (N) are determined and by means of a guidance means (13) a rotation or twisting (W1) of the fingers about their longitudinal axis is largely avoided, so that virtually coinciding, defined partial image quantities (B3, B4) of the complete enrolled fingerprint (A) are detected and transferred by evaluation algorithms into a reduced data quantity. This allows a much greater identification reliability with a smaller storage requirement and simpler evaluation algorithms.
