Abstract
Abstract An apparatus for storing flat articles comprises a first conveyor, two deflectors for diverting the articles fro the first conveyor to a second slower conveyor disposed beneath each deflector at right-angles to the first conveyor for receiving the articles in an overlapping formation, a frame adjoining the second conveyor and carrying rollers at each end, endless driven conveyor belts passing over the rollers, the frame being pivotable about the axis of one of the rollers so that the other roller is disposed adjacent to a winding for receiving covolutions of the overlapping formation of articles and so that the belts are in contact with the convolutions to turn the core, and a supply reel of holding tape associated with each winding core.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
237 words
In an apparatus for storing sacks, bags or like flat articles discharged at a high rate from a production machine, comprising a conveyor for feeding the articles to a station which combines them to form units containing larger numbers, the improvement comprising: two deflectors disposed on the conveyor behind one another in the conveying direction; a slower further conveyor below each of said two deflectors disposed at right-angles to the conveyor for feeding the articles; abutments displaced near each of said deflectors and extending parallel to the edges of each of the slower further conveyors; frames carrying rollers associated with and adjoining the downstream ends of the slower further conveyors and being pivotable about the axis of the roller closest the downstream end of the associated slower further conveyor; a machine stand; a winding core freely rotatably mounted in the machine stand; an endless driven conveyor belt supported by said frame and passing over the rollers and each frame in such manner that articles carried by the endless driven conveyor belt are applied to the winding core to form an overlapping band reel from the articles supplied in overlapping formation by the associated slower further conveyor, the endless driven conveyor belt driving the overlapping band reel; and a roller with holding tape, the holding tape extending beneath the articles guided on the frame with the leading end of the holding tape being secured on the winding core.

Claim 3
Dependent Claim
98 words
In an apparatus as claimed in claim 1 the improvement further comprising belt tensioning means associated with each endless driven conveyor belt and having two rollers fixedly mounted to the machine stand, a moveable roller mounted for movement towards and away from the two rollers, and piston means for controlling movement of the moveable roller, the endless driven conveyor belt passing through the belt tensioning means in such manner that a belt loop is formed around the moveable roller, the size of the belt loop being varied by the movement of said moveable roller by said piston means.
Claim 4
Dependent Claim
54 words
In an apparatus as claimed in claim 1, the improvement further comprising a conducting roller and a backing roller positioned between each roller with holding tape and each of the slower further conveyors, the conducting roller and the backing roller being pressed together and having a gap therebetween for passage of the holding tape.
Claim 5
Dependent Claim
31 words
In an apparatus according to claim 1, the improvement further comprising pressure bands operatively associated with the slower further conveyors for applying pressure to articles carried on the slower further conveyors
Claim 6
Dependent Claim
35 words
In an apparatus according to claim 1, the improvement wherein said conveyor for feeding the articles is adapted to extend beyond the last of said two deflectors to terminate in a depositing and packaging station.
Claim 7
Dependent Claim
53 words
In an apparatus according to claim 1, the improvement wherein each of the frames carrying rollers is in the form of a rocker which is adapted to be pressed against the overlapping band and wherein the apparatus further comprises a piston-cylinder pressure medium unit for pressing the rocker against the overlapping band real.
Claim 8
Dependent Claim
32 words
In an apparatus according to claim 1, the improvement further comprising a guide plate positioned between each of the slower further conveyors and the frames carrying rollers for guiding the holding tapes.
