Abstract
Abstract A device for positioning sheets in a stack in a sheet-processing machine includes a number of stops positioned at the front edges of the sheets being stacked for aligning the front edges of the sheets, and two joggers located at lateral sides of the stack. Each jogger includes an oscillating plate having a horizontal arm and a vertical arm which extends towards the upper end of the stack. The plate is provided with a drive imparting the oscillating movement to the vertical arm thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A device for positioning sheets in a stack in sheet transferring arrangements of sheet-processing machines, comprising first means for aligning of front edges of sheets to be stacked, second means for aligning of lateral edges of sheets to be stacked, said second aligning means including a plurality of fixed stops spaced from each other along the lateral edges of sheets being stacked and positioned at the opposite lateral sides of the sheets; and jogging means arranged in contact with the lateral edges of the sheets to be stacked, said jogging means including an oscillating plate having a horizontal arm and a vertical arm extending towards the upper end of the stack to be formed, drive means operatively connected to said horizontal arm for providing the oscillating movement of said plate towards the stack to be formed to impart impulses to falling sheets being stacked, and a compression spring adapted to bias said vertical arm in a direction toward said stack.
Claim 2
Independent Claim
160 words
A device for positioning sheets in a stack in sheet transferring arrangements of sheet-processing machines, comprising first means for aligning of front edges of sheets to be stacked, second means for aligning of lateral edges of sheets to be stacked, said second aligning means including a plurality of fixed stops spaced from each other along the lateral edges of sheets being stacked and positioned at the opposite lateral sides of the sheets; and jogging means arranged in contact with the lateral edges of the sheets to be stacked, said jogging means including an oscillating plate having a horizontal arm and a vertical arm extending towards the upper end of the stack to be formed, drive means operatively connected to said horizontal arm for providing the oscillating movement of said plate towards the stack to be formed to impart impulses to falling sheets being stacked, and a compression spring adapted to bias said vertical arm in a direction toward said stack.
Claim 3
Dependent Claim
15 words
The device of claim 1, wherein said fixed stops are located below said oscillating plate.
Claim 4
Dependent Claim
26 words
The device of claim 1, wherein said oscillating plate is pivotally supported on an axle extending along the lateral sides of the stack to be formed.
Claim 5
Dependent Claim
15 words
The device of claim 3, wherein said vertical arm is pivotally supported on said axle.
Claim 6
Dependent Claim
18 words
The device of claim 4, wherein said vertical arm is convexly shaped toward the stack to be formed.
Claim 7
Dependent Claim
39 words
The device of claim 5, wherein said drive means include a rotary shaft, an eccentric bushing mounted thereon and a sliding member connected to said bushing and arranged in contact with said horizontal arm thereby affecting said oscillating movement.
Claim 8
Dependent Claim
19 words
The device of claim 6, further including a pair of rails, said fixed stops being positioned on said rails.
Claim 9
Dependent Claim
17 words
The device of claim 7, further including means for adjusting an oscillating angle of said oscillating plate.
Claim 10
Dependent Claim
21 words
The device of claim 8, wherein said adjusting means include an adjusting screw arranged to be pressed against said horizontal arm.
