Paper tail cutter

Abstract

A paper tail cutter for cutting .Iadd.a leading edge upon .Iaddend.and deflecting a tail from a moving sheet of paper. A cutter body member is pivotally mounted to swing a knife up through the .Iadd.path of .Iaddend.the moving sheet of paper, .[.thereby cutting.]. .Iadd.to engage .Iaddend.a narrow, .Iadd.previously severed, .Iaddend.tail at one side of the moving sheet. The tail is supported by the body member and deflected away from the moving paper sheet .Iadd.as the leading edge is simultaneously cut thereon .Iaddend.for delivery to apparatus such as a stack of calender rolls.

I claim: 
     
       1. A paper tail cutter for .[.cutting and.]. deflecting a moving paper tail from .Iadd.an edge of .Iaddend.a moving sheet of paper .Iadd.and cutting said tail transversely.Iaddend., said paper tail cutter comprising: (a) a body member for supporting said moving paper tail, said body member pivotally mounted, at one end, so that the opposed end of said member may swing through the plane traversed by said moving paper sheet; .[.and,.].   (b) a first knife at said opposed end.[.;.]..Iadd.extending transversely of said body member; and,   (c) a second knife fixed with respect to said first knife to provide a scissor-like cutting action between said knives when said body member pivots to swing said first knife across said second knife; .Iaddend. whereby pivotal movement of said body member and said first knife relative to said moving paper sheet .[.cuts a portion of said moving paper sheet to yield said moving paper tail and continued pivotal movement of said body member.]. deflects said moving paper tail away from said moving paper sheet .Iadd.and cuts said tail transversely.Iaddend.. .[.2. A paper tail cutter as defined in claim 1, further comprising a second knife fixed with respect to said first knife to provide a scissor-like cutting action between said knives when said body member pivots to swing said first knife     
     
     
        across said second knife..]. 3. A paper tail cutter as defined in claim .[.2.]. .Iadd.1.Iaddend., wherein said body member has a troughed surface 
     
     
        for retaining and guiding said paper tail. 4. A paper tail cutter as defined in claim 3, further comprising powered means for pivoting said 
     
     
        body member to force said first knife across said second knife. 5. A paper tail cutter as defined in claim 4, wherein, said knives have edges contoured to cut an end of said tail shaped to ease machine handling of 
     
     
        said tail. 6. A paper tail cutter as defined in claim 5, wherein said 
     
     
        knife edges are contoured to cut a "V"-shaped end of said tail. 7. A paper tail cutter as defined in claim 4, wherein said body member is normally retracted to a position .[.beneath.]. .Iadd.to one side of the path of .Iaddend.said moving paper sheet, and wherein said second knife is fixed in position .[.above.]. .Iadd.on the opposite side of said path of .Iaddend.said moving sheet, whereby operation of said powered means pivots said body member through .Iadd.said path of .Iaddend.said sheet to deflect 
     
     
        said tail away from said sheet. 8. A paper tail cutter as defined in claim 7 further comprising a "U"-shaped frame having a first leg for pivotally mounting said one end of said body member and having a second, opposed leg for supporting said second knife.
