Title: Gravure printing
IPC: G03F5/20
Filed: 1976-06-30
Abstract: A carbon acid-resist, carrying a photosensitive bichromated-gelatine layer, is exposed to light through a gravure screen (8) having transparent lines, through a continuous-tone positive (10) superposed on a tint screen (13) and through the same positive taken in isolation. The order of these three exposures is arbitrary. Finally, the resist (top) is mounted on a gravure cylinder and developed, and the cylinder is etched with acid in the usual manner. The plate obtained has cells, the walls (22) of which are defined by the gravure screen and the bottom (20) is at a general level proportional to the density of the positive, but has, in the medium- and low-density regions of the positive, depressions (17, 21) created by the tint screen. The reproducibility of the tone values is thus improved without having to use two positives, one a continuous-tone one and the other a halftone one. <IMAGE>

Abstract: In a double-twist frame, yarn delivered from each spindle is taken up on a hank-reeling device.  The frame may be double or single-sided, and two hank-holders may serve one spindle as that one may be doffed while winding proceeds on the other.  The holder may be collapsible for case of doffing and adjustable for hanks of different dimensions. Each holder may receive two or more hanks side-by-side or superposed with a layer of paper between them. These hanks may be wound from the output of one, or more than one, spindle.  Individual holders may be mounted on a common shaft by a spring-ball clutch, Figs. 7, 8, (not shown), and hooks may be provided to assist a holder for pining.  To thread-up after doffing, the end is placed over a bar 145 with a rough surface nesting on members 149.  The bar is then moved to alternative nests 144 whereby the thread-end is carried over the base of the holder, Fig. 9, (not shown).  Alternatively, the end is placed over a similar bar forming the central axis of the holder.  The laying guides may be moved so that a number of hanks may be wound side-by-side with the output of one spindle.  The guides are mounted on a rod 102 Fig. 11 (not shown) connected to a reciprocating bar 106.  A lever 101 rotatably mounted on rod 102 is secured during a wind in a notch in a plate 108 which reciprocates with bar 106.  At the end of a wind, the lever is moved in to a notch in a stationary plate 120.  After the holder has made one revolution, the lever is moved into the next notch in the oscillating plate and a new hank is begun with a length of thread around the holder intermediate between the two hanks.  The leading, intermediate and terminal stretches of each yarn is isolated from the associated hanks by passing them over guides 153 Fig. 13, (not shown) rotatably mounted for doffing on a bar of the holder; when the hanks are to be doffed, a binder 157 is applied to each hank and the two associated ends of yarn.  To hold the severed end ready for the next wind, a bar 160 is lowered on to contact with the guides or the guides are provided with gripping members Fig. 15 (not shown) or the ends are taken up temporarily in a suction tube.
