on printing machines.

In the previously known devices for feeding envelopes, postcards , Paper sacks or the like. On printing machines, the items to be printed are advanced by pusher (gripper), which remove the stacked envelopes one by one either from above or from below to them to feed the printing device, the pusher z. B. reversibly attached, slotted Cheeks serve as guidance; in this case, however, the movement path of the pushers remains unchanged.

Another embodiment has a cutout in the bottom of the one containing the envelopes Block frame, through which the flap of the lowest envelope can fold down to get a straight path to let the guided pusher enter between the flap and the envelope.

These devices remain limited to use for envelopes since the position respectively. the point of application of the pusher is invariable, causing an advance other types of printed matter are usually excluded.

The subject matter of the present invention differs from those set out above Devices in that for feeding envelopes, postcards, paper sacks o. The like. On printing machines the fingers (grippers) causing the feed are guided on slide rods that are hinged stored on the underside of the feed table and on arch guides in different Position are adjustable.

The device is shown in the drawing by:

Fig. Ι in side view,

Fig. 4 shown in the front view.

The sliding rods c, mounted in a hinge-like manner at e, carry, by means of the two sliding bearings b, the supporting piece a, which is moved back and forth by machine; on the same the two fingers d provided with longitudinal slots d ^l are slidably mounted. The outer ends of the slide rods c slide in the guide slots f ¹ of the curved guides f attached to the underside of the feed table g and adapted to the movement curve of the slide rods c , on which the slide rods j c can be adjusted in different positions by the adjusting screws c ^l. What is achieved hereby is that the fingers d , which can be adjusted on the crosspiece α through longitudinal slots d ¹ , are changed in their direction of movement and mode of attack, so that they can ο any printed matter such as envelopes, postcards, paper sacks.

The envelopes, paper bags ο. Like. Are placed in a known manner on the table top g that the downward flaps over the recess h ^l the

Table top g lie. At the front they are limited by the means of the vertical slot guides i ¹ on the firmly screwed side cheeks k adjustable end plate i and laterally by the walls /, which are arranged ^{adjustable by means of the longitudinal slot z 2} in the end plate i , for the purpose of guidance. The bottom plate /; the recess h is ¹ ίο at / j ² bent slightly downwards in order to serve as a contact surface and support for the butt ends d ^{2 of} the fingers d. The preceding fingers d grasp the underlying printed matter, if it is an envelope, between the flap and the envelope, if it is a paper sack, between the flange and the paper sack, and if it is finally a postcard, after a suitable setting the rear edge and lead them under the rubber strip η, which is held by holders n ¹ adjustable in the slot i ' ² , and then return to their original position while the advanced printed matter is gripped by grippers and fed to the printing roller. The table top g can be filled after removing the side walls k by inserting a fitting, as indicated by the dotted line m in Fig. 1 and 2, and thus used as a smooth work table.
