Abstract
Abstract An improved slicer having a separate, controllable and relatively high speed knife, a delivery conveyor belt readily controllable in position in respect to the slicing apparatus to receive the sliced product in the desired manner, and means for automatically causing the folding of each slice to create a new and novel appearance in the subsequently packaged product. The means for automatically folding each slice of the sliced product is comprised of a member appropriately supported in the trajectory of each slice as it falls from the remaining unsliced product toward the conveyor belt so as to interrupt the trajectory of that part of the slice to result in the folding of the slice upon impingement of the conveyor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
248 words
In a slicing machine, an improved knife drive comprising a first structure supported on first and second main support bearings for rotation about a first longitudinal axis defined by said bearings, said first structure having a means between said first and second bearings for driving said first structure in rotation about said first longitudinal axis by a first drive motor; a central shaft supported by first and second central shaft bearings concentric to said first longitudinal axis for rotation about said first longitudinal axis, said first central shaft bearing being supported by said first structure between said first and second main support bearings; an offset shaft supported on first and second offset shaft bearings mounted on said first structure for rotation axis about a second axis substantially parallel to and radially offset from said first longitudinal axis, said offset shaft having a knife adjacent one end thereof at a longitudinal position between the longitudinal position of fIrst and second main support bearings; means adjacent one end of said central shaft for driving said central shaft in rotation; first coupling means on said central shaft between said first and second central shaft bearings for driving a flexible drive means; second coupling means on said offset shaft between said first and second offset shaft bearings for being driven on rotation by a flexible drive means; a flexible drive means extending around said first and second coupling means; means for driving said central shaft in rotation by a second drive motor.
Claim 2
Dependent Claim
248 words
In a slicing machine, an improved knife drive comprising a first structure supported on first and second main support bearings for rotation about a first longitudinal axis defined by said bearings, said first structure having a means between said first and second bearings for driving said first structure in rotation about said first longitudinal axis by a first drive motor; a central shaft supported by first and second central shaft bearings concentric to said first longitudinal axis for rotation about said first longitudinal axis, said first central shaft bearing being supported by said first structure between said first and second main support bearings; an offset shaft supported on first and second offset shaft bearings mounted on said first structure for rotation axis about a second axis substantially parallel to and radially offset from said first longitudinal axis, said offset shaft having a knife adjacent one end thereof at a longitudinal position between the longitudinal position of fIrst and second main support bearings; means adjacent one end of said central shaft for driving said central shaft in rotation; first coupling means on said central shaft between said first and second central shaft bearings for driving a flexible drive means; second coupling means on said offset shaft between said first and second offset shaft bearings for being driven on rotation by a flexible drive means; a flexible drive means extending around said first and second coupling means; means for driving said central shaft in rotation by a second drive motor.
Claim 3
Dependent Claim
25 words
The knife drive of claim 1 wherein said first and second coupling means are chain sprockets and said flexible drive means is a drive chain.
Claim 4
Dependent Claim
28 words
The knife drive of claim 1 wherein said means for driving said central shaft in rotation by a second drive motor comprises a drive pulley and flexible belt.
