    摘要: Photosensitive sheet handling apparatus and method for phototypesetters. Accurate control of the lateral positioning of the sheet (i.e. film) is provided by the use of tapered drive rolls (24). The apparatus includes an input cassette (2), a film input drive assembly (7) comprised of tapered pinch rollers ' (8, 10) and a film edge locating stop, a slightly tapered vacuum film drive drum (24) having a collar or flange on one side in accurate alignment with the rollers, a motor operated output drive assembly (56) also comprised of tapered pinch rollers and a film edge locating stop in accurate alignment with the drum flange, and a periodically operated film winding mechanism (142) located within an output cassette (42). The tapered rolls urge one edge of the film against the flange of the drum (24) and stops of the pinch rollers (8, 36) to maintain accurate alignment. Chambers (62, 84) are provided for receiving loops of film at the input and output sides of the drum (24). The film moves forwardly for leading, and moves in the reverse direction for reverse leading. During the reverse motion, film is withdrawn from one of the loops while another loop is formed to take up the film. This avoids the scratching and wear which otherwise would occur by repeatedly passing the film through the pinch rollers (7, 56). The film winding mechanism (142) in the output cassette winds the film under tension, but periodically relieves the tension in order to prevent the film from jamming in the output cassette (42).

    摘要: Die Erfindung betrifft eine Stanzeinrichtung für die Stanzung, insbesondere Registerstanzung, von Druckplatten, insbesondere zur Anordnung im Bereich eines Druckplattenbelichters, vorzugsweise im Randbereich einer Mulde eines Innentrommel-Plattenbelichters, umfassend einen Stanzstempel, der quer oder mehr oder weniger senkrecht zu einer Positionierfläche für die zu stanzende Druckplatte beweglich und antreibbar geführt ist und mit einem Stanzwerkzeug zum Übergriff des Randes der zu stanzenden Druckplatte ausgerüstet ist.
    Sie zeichnet sich dadurch aus, daß die Stanzeinrichtung als Durchzugsstanze ausgebildet ist, bei der das Stanzwerkzeug (4) vollständig durch die zu stanzende Druckplatte (10) durchziehbar und in oder unterhalb deren Positionierfläche (9) versenkbar ist.

    摘要: A recorded image is distorted on a printing plate when an image information for a computer is recorded in the form of a band with a band width of a plurality of image elements on a printing plate wound around a drum. This invention provides an undistorted recording on the printing plate, made possible by an arrangement that has a printing plate wound around a drum in the form of a right circular cylinder, and exposure unit to record image information in the form of a band on the printing plate by means of a light beam, a moving mechanism to move the exposure unit by one band width in the direction of the drum axis in relation to the drum while the drum makes a revolution, an image treating apparatus with the image information stored in the form of a right quadrangle, and an image modulator to rearrange and slant each band of image information readout from said image treatment apparatus by one band width in the opposite direction to the movement of said moving mechanism.
