Abstract: 977,611. Feeding adhesive labels. O. KIND, [trading as METRO-GESELLSCHAFT OSCAR KIND KOMM.-GES.]. Dec. 6, 1960, No. 42030/60. Heading A4G. [Also in Divisions B6 and B8] Relates to apparatus for printing, dispensing and applying adhesive labels which are lightly adhered to a carrier strip on a spool, the carrier strip being fed over a sharp deflecting edge which detaches the labels from the strip. According to the invention the carrier strip is fed intermittently by a feed roller and a printing stamp block is provided for printing the labels, the feed roller being driven through a oneway clutch against the action of a return spring by a drive roller actuated by a drive member on the stamp block during reciprocation thereof to print the label. In one hand operated form the stamp block 7 Figs. 1, 2 is carried at the end of a plunger 4, 5 and is provided with a shaft 8 for number type wheels 9. A clamping slide 15 with an ink pad 16 is carried on a rocking frame 14 coupled by links 13 to the block 7, so that when the block 7 is downwardly displaced, the frame 14 swings outwardly. A drive roller 24 is mounted rotatably on a shaft 23, and a feed roller 25 is rotatably mounted on the roller 24 which has wedge shaped recesses 27 in which clutch bars 28 are lodged. This arrangement forms a one-way clutch in which feed roller 25 is driven by the roller 24 in one direction but not in the other. The carrier strip 41 with labels 42 adhering to it are fed from a spool 40 and runs over the feed roller 25, over a guide roller 34 and the deflecting edge 32 and thence between the feed roller 25 and a pressure roller 31. The labels are detached at the edge 32 and present themselves for printing and application to an article by operation of the plunger 4, 5. The feed roller 25 is operated via the one-way clutch and roller 24 by means of an arm 43 on the stamp block 7 which engages a driving peg 44 on the roller 24. At the end opposite the peg 44, the roller 24 carries another peg 45 engaged by a spring 46 urging the roller 24 counter to the direction of the arrow X. The operative path of the feed roller 25 is adjustable and thus the feed of the carrier strip 41 can be adjusted according to the size of the labels on it. Where the labels have to be applied to curved surfaces, it may be desirable to print the labels and then to remove them by hand after passage over the deflecting edge. For this purpose a plate 57 is inserted over the window frame 20, the rear edge 58 of the plate abutting the deflecting edge 32 and the front edge 59 now constituting the deflecting edge. In another power-operated embodiment the carrier strip 117 Fig. 6 is fed from a spool 115 over guide rollers 118, 119, 120 to a dispensing slot 121 in a cover hood 102. In the slot 121 is journalled a dispensing and application roller 125, and a hinged control flap 127 covers the rest of the slot 121, the flap being spring urged to project upwardly beyond the plane of the cover hood. Between the guide rollers 119, 120 the carrier strip is led over a counter pressure plate 133 for the reciprocating stamp block 138 Fig. 9 which is held in the rest position by a spring 141. The type wheels 137 carried by the block 138 are settable by setting buttons 144 and are provided with an insertable carrying plate 173 for four additional lines of easily-exchangeable rubber types and with an inking pad 145, the carrying frame of which is swung out of the way during the working stroke of the stamp block. The carrier strip 117 passes around a deflecting edge 167, in the form of a roller, to present labels to the roller 125 and then passes between a feed roller 148 and a pressure roller 149 and is discharged to the outside. The roller 148 is provided with a free wheel clutch 147 similar to the roller 24 of the first embodiment. A rack 155 is secured to the stamp block 138 and is displaced by a toothed segment 156. During the working stroke of the block 138, the rack end 157 engages a lug 158 on the clutch 147 and the roller 148 is rotated and printing on the label lying on the counter pressure plate 133 is effected. The toothed segment 156 is coupled to a constantly running motor 159 through a single revolution clutch. The object to be labelled is guided over the cover hood 102 and pushed over the application roller 125 so that the label lying against the roller is rolled on to the object. The control flap 127 is now depressed by the object and by means of a rocker 129 and the single revolution clutch initiates the next feed step for the feeding of the carrier strip 117 and the printing of the first label not yet printed. The printing mechanism may be disconnected when the apparatus is used for dispensing preprinted advertising labels. Specifications 977,612 and 977,613 are referred to.
