Abstract
Abstract Apparatus for conveying sheets emanating from transverse cutters or other sheet-ejecting machines in a flow line of successive end to end sheets in which the sheets are overlapped by upper and lower conveyor belt means with conveyor belt drive means being operative to move one conveyor belt means slower than the other conveyor belt means so that each successive sheet is overlapped with the immediately preceding sheet, the slower moving conveyor belt being stopped in response to the absence of at least one sheet in the flow line of successive sheets, the drive means for the slower conveyor belt means including a differential gear means including an input drive shaft and two driven shafts and means are operatively associated with said differential gear means for alternatively stopping and releasing both driven shafts.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
In apparatus for conveying sheets emanating from a transverse cutter or other sheet ejecting machines, means for receiving and moving ejected sheets in a flow line of successive end-to-end sheets, means for overlapping moving sheets including upper and lower conveyor belt means, drive means for said conveyor belt means including means operative to move one conveyor belt means slower than the other conveyor belt means so that each successive sheet is overlapped with the immediately preceding sheet, means for stopping said slower moving conveyor belt means in response to the absence of at least one sheet in the flow-line of successive sheets, and the drive means for said slower conveyor belt means including a differential gear means including an input drive shaft and two driven shafts and means operatively associated with said differential gear means for alternatively stopping and releasing both driven shafts.
Claim 2
Dependent Claim
143 words
In apparatus for conveying sheets emanating from a transverse cutter or other sheet ejecting machines, means for receiving and moving ejected sheets in a flow line of successive end-to-end sheets, means for overlapping moving sheets including upper and lower conveyor belt means, drive means for said conveyor belt means including means operative to move one conveyor belt means slower than the other conveyor belt means so that each successive sheet is overlapped with the immediately preceding sheet, means for stopping said slower moving conveyor belt means in response to the absence of at least one sheet in the flow-line of successive sheets, and the drive means for said slower conveyor belt means including a differential gear means including an input drive shaft and two driven shafts and means operatively associated with said differential gear means for alternatively stopping and releasing both driven shafts.
Claim 3
Dependent Claim
39 words
Apparatus as claimed in claim 1 in which one of said two driven shafts of the differential gear means drives the slower moving conveyor belt means, while the other driver shaft is an idler shaft which can be stopped.
Claim 4
Dependent Claim
95 words
Apparatus as claimed in claim 2 in which said input shaft of the differential gear means is continuously rotating, the power train through said differential gear means being transmitted to the slower conveyor belt means from said input shaft by said one driven shaft when said idler shaft is stopped and said one driven shaft released, and the power train through said differential gear means being transmitted from said input shaft to said idler shaft when said one driven shaft is stopped to stop said slower moving conveyor belt and said idler shaft is released.
Claim 5
Dependent Claim
150 words
Apparatus as claimed in claim 3 in which the means operatively associated with said differential gear means for alternatively stopping and releasing both driven shafts includes a band brake means for each driven shaft, each bank band brake means having a pulling end, a cylinder, a piston means movable within said cylinder and having opposite end portions, said pulling ends of the band brake means being connected to the opposite end portions of said piston means, and means for controlling reciprocating movement of said piston means so that when one band means is applied to stop its associated driven shaft, the other band means releases its associated driven shaft when the piston means moves in one direction, and said other band means is applied to and stops its associated driven shaft and said one band means releases its associated driven shaft when the piston means moves in the opposite direction.
