Abstract
An improved cutter blade assembly for cutting vegetable products such as potatoes. The cutter blade assembly utilizes a number of cutter blades that transverse an axial bore through which products to be cut are fed. These blades are locked within the assembly by an attachment system that partially deforms the blade to hold the blade in place. This improved attachment connection system serves to hold the blade in a position having higher tension and thereby reduces wear, chatter, and feathering.
Claims23
A cutter assembly for cutting vegetable pieces in a hydraulic cutter assembly comprising:
- a first body having first and second blade mounting surfaces and defining a first axial bore;
- and
- a first blade traversing said bore, said first blade having a first end and a second end, said first end configured to be connected to said first blade mounting surface and a second end configured to be connected to said second blade mounting surface;
- said first blade mounting surface defining a portion configured to interact with a holding device to deform and hold a portion of said blade against said first mounting surface when said blade is held in compressive engagement between said holding device and said first mounting surface by a fastener.

A cutter assembly for cutting vegetable pieces in a hydraulic cutter assembly comprising:
- at least two bodies, each body having a plurality of first blade mounting surfaces and a plurality of second blade mounting surface, and defining between said bodies an axial bore;
- and
- a plurality of blades traversing said bore, each of said blades having a first end and a second end, each of said first ends connected to a first blade mounting surface and each of said second ends connected to a second blade mounting surface;
- each of said first and second mounting surfaces defining a recess configured to interact with a crimping flange portion of a holding device to deform and hold a portion of said blade against said mounting surfaces when said blade is held in compressive engagement between said holding devices and said mounting surfaces by a fastener.

An improved cutter assembly configured for cutting vegetable pieces in a hydraulic cutter assembly comprising:
- a plurality of tensioning trees spatially arranged in opposing pairs and defining between them an axial bore configured for passage of materials to be cut there through, each tree having a plurality of first blade mounting surfaces and a plurality of second blade mounting surfaces;
- a flow alignment control tube configured to be placed within said axial bore;
- a plurality of blades traversing said bore in a non-interfitting generally perpendicular pattern, each of said blades having a first end and a second end, each of said first ends connected to a first blade mounting surface and each of said second ends connected to a second blade mounting surface each of said first and second mounting surfaces define a recess and an anvil both the recess and the anvil configured to interact with a crimping flange portion of a holding clamp to deform and hold a portion of said blade against said mounting surfaces when said blade is held in compressive engagement between one of said holding devices and said mounting surfaces by a fastener;
- a tensioning mechanism configured to adjustably maintain a desired level of tension upon said elongated blade, said tensioning mechanism is comprised of an adjustable screw held in compressive engagement against a tensioning dowel pin within a holding clamp, said holding clamp configured to hold said tensioning dowel against said blade and to advance a portion of said blade into a tensioning recess formed within a mounting surface;
- a compression ring connected to said bodies, said compression ring configured to allow passage of cut materials out of said cutter assembly along said bore as well as to maintain a desired distance between said bodies about said axial bore.
