Rotary shear assembly

Claim 2

Apparatus comprising a rotary shear assembly positioned between a double facer machine and a slitter-scorer of a corrugator, said assembly comprising a rotary shear at the upstream end of the assembly and a frame having a web support surface at the downstream end of the assembly, said rotary shear including a rotatably mounted cutting blade for repetitively cutting a web transversely into sheets, means for receiving sheets cut by the rotary shear, a diverter supported by said frame downstream from the rotary shear, said diverter being mounted for movement from an inoperative position wherein it does not interfere with normal passage of a web to an operative position wherein it prevents sheets from moving along a path normally followed by a web, said surface being spaced from the downstream end of the rotary shear by a gap, said gap being upstream from the diverter, said sheet receiving means being below said surface, said diverter having forward and rear portions converging to a crest, and means coupled to said diverter for pivoting said diverter about a horizontal transverse axis adjacent said crest.

Claim 3

Apparatus comprising a rotary shear assembly positioned between a double facer machine and a slitter-scorer of a corrugator, said assembly including a rotary shear at the upstream end of the assembbly adjacent said double facer machine and a web support surface at the downstream end of the assembly, said surface being spaced from the downstream end of the rotary shear by a gap, said rotary shear including a rotatably mounted shear roll having a cutting blade for selectively and repetitively cutting the web transversely into sheets, means below the elevation of said surface for receiving sheets cut by the rotary shear, a diverter between said Surface and said rotary shear, said diverter mounted for movement from an inoperative position where it does not interfere with normal passage of a web to an operative position wherein it projects above the elevation of said surface to prevent sheets from moving along a path normally followed by a web, a sloping wall extending from the downstream end of the rotary shear and below the elevation of the gap for directing sheets toward said sheet receiving means, said diverter having forward and rear portions converging to a crest, and means coupled to said diverter for pivoting said diverter about a horizontal transverse axis adjacent said crest.

Claim 4

Apparatus comprising a rotary shear assembly positioned between a double facer machine and a slitter-scorer of a corrugator, said assembly including a rotary shear at the upstream end of the assembbly adjacent said double facer machine and a web support surface at the downstream end of the assembly, said surface being spaced from the downstream end of the rotary shear by a gap, said rotary shear including a rotatably mounted shear roll having a cutting blade for selectively and repetitively cutting the web transversely into sheets, means below the elevation of said surface for receiving sheets cut by the rotary shear, a diverter between said Surface and said rotary shear, said diverter mounted for movement from an inoperative position where it does not interfere with normal passage of a web to an operative position wherein it projects above the elevation of said surface to prevent sheets from moving along a path normally followed by a web, a sloping wall extending from the downstream end of the rotary shear and below the elevation of the gap for directing sheets toward said sheet receiving means, said diverter having forward and rear portions converging to a crest, and means coupled to said diverter for pivoting said diverter about a horizontal transverse axis adjacent said crest.

Claim 5

Apparatus in accordance with claim 2 wherein said means for receiving sheets includes a conveyor for conveying the sheets in a direction parallel to the axis of said shear roll.

Claim 6

Rotary shear assembly in accordance with claim 2 including a sloping wall extending from the downstream end of the rotary shear and below the elevation of the gap for directing sheets to said sheet receiving means.

Claim 7

Rotary shear assembly in accordance with claim 2 wherein said means below the elevation of said surface for receiving sheets includes a conveyor below said surface for conveying the sheets in a direction parallel to said axis.

Claim 8

Rotary shear assembly in accordance with claim 2 including an anvil roll for continuous rotatably contact with the web below and in cooperating relation with said shear roll.
