Abstract
Abstract Apparatus for shingling or overlapping sheets having a highspeed upper tape system extending in overlying relationship from a lower, high-speed tape system to an overlying relationship with a low-speed, lower or overlap tape system. The upper surface of the low-speed tape system is disposed at a level substantially below the upper surface of the lower, high-speed tape system. Also the upper tape system has a substantial angle of inclination formed with the sheet-receiving surface of the low-speed tapes with a deflector located at the angle of inclination and in superposed relation to the upper surface of the low-speed tapes.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
350 words
Apparatus for overlapping cut size sheets comprising a highspeed tape conveyor system, a low-speed tape conveyor system, the delivery end of the high-speed tape system being adjacent the receiving end of the low-speed tape system, the sheet-carrying surface of the low-speed tapes being disposed at a level substantially lower than the sheet-carrying surface of the highspeed tapes, an upper tape system in the form of a loop with its lower run disposed in superposed relation to the upper run of the high and low-speed systems, means for driving the upper and highspeed tape systems at substantially the same speed and for driving the low-speed tape system at a substantially lower speed, a stop roll rotatably disposed to engage the leading edges of sheets carried between the lower run of the upper tape system and the upper run of the lower tape system and being located at a distance from the delivery end of the high-speed tapes which is approximately equal to the length of said cut size sheets, and a deflecting roll for the tail end portions of said cut size sheets being located intermediate said stop roll and said receiving end of the low-speed tapes at a distance from the stop roll which is a function of the length of said cut size sheets, said deflector roll being disposed within the upper tape system and positioned to retain the lower run thereof at a substantial angle of inclination from the delivery end of said high-speed tapes to the receiving end of said low-speed tapes and from the deflector roll to the stop roll in closely spaced generally parallel relationship to the upper run of the low-speed tapes whereby at approximately the same time that the leading edges of said sheets engage said stop roll the tail end portions of said sheets upstream of said deflector roll are deflected into the plane of the upper run of the low-speed tape system by the deflector roll, and whereby the portions of said sheets between said stop roll and deflector roll are restrained against buckling by the closely spaced generally parallel tapes.

Apparatus for overlapping cut size sheets comprising a highspeed tape conveyor system, a low-speed tape conveyor system, the delivery end of the high-speed tape system being adjacent the receiving end of the low-speed tape system, the sheet-carrying surface of the low-speed tapes being disposed at a level substantially lower than the sheet-carrying surface of the highspeed tapes, an upper tape system in the form of a loop with its lower run disposed in superposed relation to the upper run of the high and low-speed systems, means for driving the upper and highspeed tape systems at substantially the same speed and for driving the low-speed tape system at a substantially lower speed, a stop roll rotatably disposed to engage the leading edges of sheets carried between the lower run of the upper tape system and the upper run of the lower tape system and being located at a distance from the delivery end of the high-speed tapes which is approximately equal to the length of said cut size sheets, and a deflecting roll for the tail end portions of said cut size sheets being located intermediate said stop roll and said receiving end of the low-speed tapes at a distance from the stop roll which is a function of the length of said cut size sheets, said deflector roll being disposed within the upper tape system and positioned to retain the lower run thereof at a substantial angle of inclination from the delivery end of said high-speed tapes to the receiving end of said low-speed tapes and from the deflector roll to the stop roll in closely spaced generally parallel relationship to the upper run of the low-speed tapes whereby at approximately the same time that the leading edges of said sheets engage said stop roll the tail end portions of said sheets upstream of said deflector roll are deflected into the plane of the upper run of the low-speed tape system by the deflector roll, and whereby the portions of said sheets between said stop roll and deflector roll are restrained against buckling by the closely spaced generally parallel tapes.
Claim 3
Dependent Claim
29 words
Apparatus as set forth in claim 1 in which the distance between the stop roll and deflector roll is approximately 2-4 inches less than the length of said sheets.
