Abstract: 1288505 Eye-lines BRIDAL AG 9 Jan 1970 [8 May 1969] 1256/70 Heading A5R [Also in Division B5] Preformed eye-lines having a contour formed by two curved lines tapering to a point at each end of the eye-line are produced by punching and the eye-line by two successive incisions from a web having a selfadhering adhesive coating adhering with its adhesive side to a backing material, one of the curved lines being cut by the first incision and the other curved line being cut by the second incision, each incision completely severing the web and at least one of the incisions also cutting the backing material in places, and subsequently stripping the portions of the web outside the eye-line contour from the backing material. The web may be of paper synthetic plastics material or woven fabric and the backing material of cardboard or paper. The web with its backing material may be supplied in the form of a band and may be cut longitudinally into several partial bands prior to punching, the bottom face of the backing material being scored along two longitudinally extending lines which will pass in proximity and under the pointed ends of the contour of the eyelines to be punched out to ensure easy separation from the backing material when the eye-lines are used. In Fig. 1 two layer material band 2 comprising web 19 and backing material 20 is drawn off roller 1 and fed to working table 9 through continually operating longitudinal cutting device 8 which cuts it into partial bands and at the same time effects longitudinal scoring of the undersides of the partial bands along two lines. The cutter head 10 is intermittently moved up and down according to a predetermined working cycle, the first curved lines of the eye-lines being punched out transversely by a group of knives 11 and, after a predetermined forward movement of the band, the second curve lines closing the contour of the eye-lines being cut transversely with a group of knives 12. In order that the backing material is not completely cut across at all points the table may be provided with a series of longitudinal grooves so that when the knives move downwardly to cut the curved contours of the eyelines and abut against the surface of the table the lowermost portions of the backing material situated on top of the grooves are pushed slightly into the grooves and are not cut by the knives. The band of material is transported over the working table by means of rollers 13 and 14 which are driven intermittently, the roller 14 also serving as a guide roller to strip the portion of web 19 not belonging to the eye-lines 23 but situated outside the cutting lines from backing material 20 and feed it to drive rollers 15 and 16.

Title: Pattern control for printing machine
IPC: B41F17/00
Filed: 1969-09-17
Abstract: 1313109 Printing apparatus COURTAULDS Ltd 16 Sept 1970 [17 Sept 1969] 45739/69 Heading B6C In a machine comprising a number of printing heads 2 ... 5 Fig. 1, operating on material passed therethrough continuously, e.g. a machine for printing a pattern of differently coloured bars across a warp of yarns, the operation of each printing head is controlled by a driven pattern disc 6 ... 9, one for each head. In one embodiment, the discs 6 ... 9 are of metal and have parts of their peripheries masked with insulating tape according to the pattern required, and electrical brushes contact the peripheries and operate control circuits for pneumatic piston and cylinder mechanisms for moving presser rollers 2d ... 5d towards dye-coated rollers 2c ... 5c at the requisite times to print the pattern of colour bars on the material. The discs 6 ... 9 are mounted side by side on a shaft (10, Fig. 3) and have a first set of registering holes 6b ... 9b through which a pin (12) is passed, and the pieces of insulating tape are attached in a pattern which visually corresponds to the required printed pattern. However, the discs thus positioned would not produce the required pattern because of the distance to be traversed by the material between successive printing heads. To take account of this, the pin (12) is now withdrawn from the holes 6b ... 9b and the discs are relatively rotated so that the pin can be inserted through a second set of holes 6c ... 9c, the spacing of which allows for the spacing of the printing heads. Instead of using insulating tape as described above, each disc may have a series of holes into which pegs can be fitted, which trip levers for actuating the printing heads. In another form, a jet of air is directed at the periperhal surface of each pattern disc which has holes in the peripheral surface. The holes are plugged according to the pattern required causing changes in the back pressure on the jet to effect the control of the printing heads. In these modified constructions, the pattern can be changed by altering the spacings between the pegs, or the holes which are plugged.
