Title: Transfer Sheet having a Hidden Pattern
IPC: B44C1/17
Filed: 1967-04-13
Abstract: 1,180,477. Transfer sheet. TOPPAN PRINTING CO. Ltd. 13 April, 1967 [14 April, 1966; 14 Dec., 1966; 22 Dec., 1966], No. 16925/67. Heading B6C. A transfer sheet comprises a transparent or translucent base sheet, a releasable pattern printed on the base sheet and an adhesive layer over the pattern wherein at least part of the pattern is rendered invisible through the base sheet. In the first embodiment, Fig. 1, the transfer sheet comprises a transparent or translucent synthetic resin film 1, a releasable pattern 2 in colourless, transparent ink, a coloured layer 3, a pressure-sensitive adhesive 4 and a release layer 5 for a temporary support 6; the pattern cannot therefore be distinguished through the base sheet, and only becomes visible on transfer (Figs. 2-4, not shown). The temporary support 6 is stripped off, adhesive layer 4 is contacted with the receiving surface and due to the relative adhesions, only those parts of coloured layer 3 which overly the pattern 2 remain bonded to the adhesive layer 4 when base sheet 1 is removed. A second embodiment, not shown, comprises printing the pattern 2 on the base sheet 1 in monochromatic ink which is given an overall layer of adhesive 4; the base sheet 1 is then covered on the side remote from the pattern side, with a translucent layer of the same colour as the pattern 2. Alternatively, the base sheet itself could be coloured. A third embodiment, Fig. 11, comprises printing in at least two colours 2a, 2b, and then providing a coloured translucent layer 7 on the reverse side of sheet 1 which absorbs light of at least one of the two colours, this idea being extendable to multi-colour patterns. A releasable layer 8, Fig. 11, may optionally be provided between the base sheet 1 and pattern 2, and a further covering layer can be provided over pattern 2 to prevent it from being distinguished through the adhesive layer 4.

[Class 100 (i).] In an arrangement of feed or guide tapes for threading a web through a printing-machine, the tape is carried over runners disposed at positions before the tape normally contacts the impression cylinder and beyond the point where the tape leaves the cylinder, the runners being movable, when desired, towards one another about the surface of the impression cylinder which drives the tape to move the tape out of contact therewith. The tape a, Fig. 1, during the threading operation is driven by contact with driving surfaces on the impression cylinders b, f, and is afterwards moved into the position shown in dotted lines out of contact with the impression surfaces. This is effected by the operation of a pair of runners i, arranged adjacent to each impression cylinder and operated simultaneously by means of an operating handle n. The runners i, j are carried by pairs of arms g, h, o, p pivoted about the axis of the impression cylinders and provided with gear segments g<1>, h<1> connected by gearing k, l, q. The runners are held in the operative position by a projection i<2> engaging a catch r.
