Abstract
Abstract Stacks of superimposed paper sheets are formed from a succession of layers each of which contains a given number of groups of sheets. One or more layers which contain a first number of groups can be followed by one or more layers containing a different second number of groups so that a stack can contain layers which, in turn, contain different numbers of groups and hence different numbers of sheets. The number of sheets in each stack and in each layer is a whole multiple of the number of sheets in a group. If the average number of sheets in a series of successive stacks is to deviate from a whole multiple of the number of sheets in a group, successive stacks contain different numbers of sheets; each such number is a whole multiple of the number of sheets in a group but the total number of sheets in the series of stacks divided by the number of stacks which form the series can deviate from such whole multiple.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
137 words
A method of forming stacks of paper sheets or the like, comprising the steps of forming a succession of groups of overlapping sheets each containing a predetermined number of sheets; accumulating at least one first layer from a first number of successively formed groups; thereupon accumulating at least one second layer from a different second number of successively formed groups; and accumulating said first and second layers into a stack containing a total number of n sheets equal to z 1 times r times p+z 2 times r times q wherein r is the number of sheets in a group, z 1 is the number of groups in a first layer, p is the number of first layers, z 2 is the number of groups in a second layer and q is the number of second layers.
Claim 2
Independent Claim
137 words
A method of forming stacks of paper sheets or the like, comprising the steps of forming a succession of groups of overlapping sheets each containing a predetermined number of sheets; accumulating at least one first layer from a first number of successively formed groups; thereupon accumulating at least one second layer from a different second number of successively formed groups; and accumulating said first and second layers into a stack containing a total number of n sheets equal to z 1 times r times p+z 2 times r times q wherein r is the number of sheets in a group, z 1 is the number of groups in a first layer, p is the number of first layers, z 2 is the number of groups in a second layer and q is the number of second layers.
Claim 3
Dependent Claim
65 words
The method of claim 1, wherein said group forming step comprises establishing several discrete sources of successive coherent sheets, drawing coherent sheets from such sources so that successive coherent sheets drawn from one source register with successive coherent sheets drawn from each other source, and repeatedly severing all coherent sheets to separate successive foremost sheets therefrom whereby the separated foremost sheets together constitute a group.
Claim 4
Dependent Claim
28 words
The method of claim 1, further comprising the steps of accumulating groups into layers at a first station and accumulating layers into stacks at a discrete second station.
Claim 5
Dependent Claim
38 words
The method of claim 3, further comprising the step of transferring successively formed layers from the first to the second station at different intervals whose duration is a function of the number of groups in the respective layers.
Claim 6
Dependent Claim
37 words
The method of claim 1, further comprising the step of shifting in resonse to the accumulation of first layers to the accumulation of second layers upon completion of the formation of a preselected number of first layers.
Claim 7
Dependent Claim
71 words
The method of claim 1, further comprising the step of accumulating at least one additional stack wherein the number of sheets is different from the number of sheets in the preceding stack and the combined number of sheets in the preceding and additional stacks equals y times N wherein y is the total number of stacks and N is not a whole multiple of the number of sheets in a group.
Claim 8
Dependent Claim
48 words
The method of claim 6, wherein y equals x 1 +x 2 and x 1 is the number of stacks having N-a sheets, x 2 being the number of stacks having N+b sheets, N-a and N+b being whole multiples of r, and a and b being whole numbers.
Claim 9
Dependent Claim
40 words
The method of claim 1, further comprising the step of storing information pertaining to the numbers of first and second layers and utilizing the thus stored information for the assembly of requisite numbers of first and second layers into stacks.
Claim 10
Dependent Claim
63 words
The method of claim 8, further comprising the steps of transferring successively formed layers from a first to a discrete second station at different intervals whose duration is a function of the number of groups in the respective layers, and selecting the speed of removal of layers from the first station to the second station in dependency on at least one variable parameter.
Claim 11
Dependent Claim
31 words
The method of claim 4 wherein said parameter includes the maximum permissible speed of at least one driven unit in the apparatus which is utilized for the practice of the method.
Claim 12
Independent Claim
212 words
A method of forming stacks of paper sheets or the like, comprising the steps of forming a succession of groups of overlapping sheets each containing a predetermined number of sheets, including superimposing several coherent sheets and repeatedly severing such superimposed coherent sheets to separate successive foremost sheets therefrom whereby the separated foremost sheets together constitute a group; accumulating at least one first layer from a first number of successively formed groups at a first station; transferring the first layer from the first station to a second station; accumulating at the first station at least one second layer from a different second number of successively formed groups each containing a predetermined number of sheets; transferring the second layer from the first to the second station; and stacking the first and second layers at the second station so that the first and second layers form a stack containing a total number of n sheets equal to z 1 times r times p+z 2 times r times q wherein r is the number of sheets in a group, z 1 is the number of groups in a first layer, p is the number of first layers, z 2 is the number of groups in a second layer and q is the number of second layers.
