Magazines, etc.

Machines for the automatic lifting, folding and wrapping of newspapers, magazines and the like, in which the newspapers are folded one after the other by two folding knives crossing each other at a right angle are known. The present invention now consists in that in the plane of motion of the first folding knife continuously moving endless chains with the same seated fingers are arranged so that after the first folding knife the Once the newspaper has been folded, put your fingers in the fold of the newspaper and remove the newspaper Bring in front of the second folding knife at which point the finger will automatically move out of the newspaper fold will.

Fig. Ι and 2 show the arrangement of the chains.

The newspapers, magazines, etc. are in a known manner from platforms of a Lifted up in packs and then individually lifted off by the reciprocating gripper arm 58 of a lifting device. lifted and successively brought under the first folding knife 84 by conveyor belts, which from a vibrating shaft by an arm 86 in guides 85 and is moved down, the folding knife each time folding a newspaper and the same up with a cover strip around it between guide rollers into one of guides 141 enclosed space. As soon as the newspaper entered this room is, the folding knife 84 goes up again. On both sides of the guides 141 are over on waves 144, 145, 146, 147 seated driving wheels running articulated chains 143 arranged, each with one between two limbs seated fingers 142 are provided. Shaft 146 is driven by link chains driven by the main drive shaft of the machine. Wave 144 joins wave 146 driven by bevel gears seated at the end of a transverse shaft.

The movement of the chains 143 is controlled so that as soon as the folding knife 84 the Upward movement begins, grasp fingers 142 in the fold of newspaper and the newspaper bring down in front of the second folding knife 150 directed perpendicular to the first, at what time they release the newspaper. To this end are the lower ones Shafts 145, 147, over which the link chains 143 run, swinging on the shafts 144, 146 mounted frame 151, which are adjustable in length and are provided with gears 152, which in on Gear wheels 153 seated on shafts 145, 147 intervention. On the gears 152 are Thumb 154 attached. In that the downward movement of the chains 143 sitting fingers 142 respectively the gears 153 with their shafts 145. 147 turn, become the gears 152 are also rotated and thereby the thumbs 154 sitting on the same

Notices 155 approached. If the newspaper goes far enough through the fingers 142 is guided below, the thumbs 154 meet the stops 155 and the swinging Frame 151 are pushed outward and thus fingers 142 out of the Newspaper fold moved out, so that now the second folding knife 150, which is from the main shaft 32 is moved back and forth from by means of an eccentric and a rod 159 connected to the knife, the newspaper can fold for the second time.

Claims (1)

Patent claim: Folding device with two folding blades moving at right angles to each other on a machine for the automatic lifting, folding and wrapping of newspapers, magazines, etc., thereby characterized in that between the first and second folding knife continuously moving endless chains (143) each with one Fingers (142) are attached so * that at the beginning of the upward movement of the first folding knife (84) the fingers (142) enter the newspaper fold and the Guide the newspaper in front of the second folding knife, with the chains (143) swinging Frame (151) are mounted in such a way that when the newspaper is in front of the second folding knife, by pressing outwards the frame automatically moves the fingers (142) out of the newspaper fold will. 1 sheet of drawings.
