Abstract

Abstract A method and machine or receiving a continuous stream of signatures from a printing press and producing vertical stacks of accurately aligned signatures wherein the signatures are first aligned in he direction conveyance, individually curved to increase their rigidity and projected into a supporting collector to align their leading edges. Each signature is maintained in alignment with the others while the stack is forming by means of continuous jogging and rotating brushes continuously depressing the side and back edges the uppermost signatures. The completed stack discharged to a compressor and binder.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 320 words
In a method of continuously forming stacks of accurately aligned signatures comprising the steps of: a. conveying a line of signatures into and through a first zone; b. prejogging the line of moving signatures within the first zone transversely to the direction of conveyance to align the side edges of the signatures extending in the direction of conveyance; c. discharging each signature from the oncoming line of remaining signatures in the direction of conveyance; d. curving each signature about an axis extending in the direction of conveyance as it is discharged; e. halting the conveyance movement of each discharged signature with its edge at a predetermined location; f. collecting a stack of halted signatures with their leading, trailing and side edges aligned, the improvements comprising; g. jogging the forming stack of signatures as they are being collected; h. intermittently conveying the line of signatures through the first zone by selectively varying the speed therein between complete halt, a top speed and an intermediate speed; i. interposing a second zone between said first zone and step e) above, and conveying the signatures through said second zone, both zones normally conveying at the same top speed; j. increasing the distance between leading edges of adjacent signatures within the second zone; k. intermittently conveying the line of signatures through said second zone by halting the conveyance of signatures in said second zone when a predetermined number of them has been collected; l. slowing the rate of conveyance of signatures through said first zone simultaneously with the halting of conveyance in said second zone; m. removing the stack of collected signatures a predetermined time after the conveyance has been slowed in said first zone; n. halting the conveyance of signatures in said first zone simultaneously with the removal of a stack of collected signatures; o. resuming conveyance of signatures through said first and second zones at the same speed as in step i) above.
Claim 2
Dependent Claim 320 words
In a method of continuously forming stacks of accurately aligned signatures comprising the steps of: a. conveying a line of signatures into and through a first zone; b. prejogging the line of moving signatures within the first zone transversely to the direction of conveyance to align the side edges of the signatures extending in the direction of conveyance; c. discharging each signature from the oncoming line of remaining signatures in the direction of conveyance; d. curving each signature about an axis extending in the direction of conveyance as it is discharged; e. halting the conveyance movement of each discharged signature with its edge at a predetermined location; f. collecting a stack of halted signatures with their leading, trailing and side edges aligned, the improvements comprising; g. jogging the forming stack of signatures as they are being collected; h. intermittently conveying the line of signatures through the first zone by selectively varying the speed therein between complete halt, a top speed and an intermediate speed; i. interposing a second zone between said first zone and step e) above, and conveying the signatures through said second zone, both zones normally conveying at the same top speed; j. increasing the distance between leading edges of adjacent signatures within the second zone; k. intermittently conveying the line of signatures through said second zone by halting the conveyance of signatures in said second zone when a predetermined number of them has been collected; l. slowing the rate of conveyance of signatures through said first zone simultaneously with the halting of conveyance in said second zone; m. removing the stack of collected signatures a predetermined time after the conveyance has been slowed in said first zone; n. halting the conveyance of signatures in said first zone simultaneously with the removal of a stack of collected signatures; o. resuming conveyance of signatures through said first and second zones at the same speed as in step i) above.
Claim 3
Dependent Claim 28 words
The method as set forth in claim 1, wherein: said slow rate of conveyance through said first zone is about 1/5 the regular conveyance through said first zone.
Claim 4
Dependent Claim 72 words
the removal of said stack on said signatures conveyor means, and signaling said first and second power means to a. stop said second conveyor means and simultaneously slow said first conveyor means when said stack of signatures has been completed, b. stop said first conveyor means when said stack is being removed on said signature conveyor means; c. starting both said first and second conveyor means after said stack has been removed.
Claim 5
Dependent Claim 72 words
the removal of said stack on said signatures conveyor means, and signaling said first and second power means to a. stop said second conveyor means and simultaneously slow said first conveyor means when said stack of signatures has been completed, b. stop said first conveyor means when said stack is being removed on said signature conveyor means; c. starting both said first and second conveyor means after said stack has been removed.
Claim 6
Dependent Claim 21 words
The method as set forth in claim 1, wherein: said signatures are overlapping during conveyance through at least the first zone.
Claim 7
Dependent Claim 36 words
The method as set forth in claim 5, wherein: the leading edges of said overlapping signatures in said second zone are spaced apart about half the distance between the leading and trailing edge of a signature.
Claim 8
Dependent Claim 32 words
The method as set forth in claim 1, further including the step of: continuously depressing the edges of at least two sides of a stack of signatures as they are being collected.
Claim 9
Dependent Claim 25 words
The method as set forth in claim 1, further including the step of: precompressing the folded edges of said signature prior to their being discharged.
Claim 10
Dependent Claim 33 words
The method as set forth in claim 1, further including the step of: compressing the stack of collected signatures to make the stack more compact and acceptable to process into a binder machine.
Claim 11
Dependent Claim 289 words
In apparatus for continuously forming stacks of accurately aligned signatures comprising: a frame having a plurality of independently operable conveyor means mounted substantially horizontally successively thereon, said frame having first and second zones; first conveyor means within said first zone for receiving a continuous line of signatures as from a press; first power means connected to drive said first conveyor means; prejogging means mounted on said frame within said first zone to assist in aligning the sides of the signatures; second conveyor means in said second zone downstream of said first conveyor means for receiving said signatures therefrom; second power means connected to drive said second conveyor means; signature-handling means to guide each signature and discharge it from said second zone; collection means for receiving a predetermined number of signatures from said handling means and forming a stack thereof and capable of moving said stack, said collection means comprises a bottom support, a pair of joggers on either side thereof and a front wall extending transversely in the direction of signature discharge, said wall positioned to intercept each discharged signature to assist in aligning the leading edges of the forming stack; signature conveyor means to receive said stack of signatures from said collection means; the improvement comprising said first and second power means selectively halting and moving said first and second conveyor means at various speeds in response to predetermined signals; said first conveyor means includes a separate driven conveyor means; a stripper assembly is mounted in position relative to said separate conveyor means to spread the signatures apart in the direction of conveyance a distance greater than they are in the oncoming direction of said first conveyor means; switch means connected to said collection means capable of sensing
