SYSTEM OF CUTTING A HOMOGENEOUS WORK PRODUCT INTO NATURAL SHAPES WITH RANDOMNESS
20220203569 · 2022-06-30 · ·

A system 10 may be used to carry out methods for portioning substantially uniform food products 12 into a series of intentionally created unique variations of one or more predetermined reference shapes to resemble naturally occurring food product shapes. The method includes scanning the uniform food product and generating digital data based on the results of the scanning. This data is used to generate a series of unique variations of one or more predetermined reference shapes based on one or more specified physical parameters for the unique variation shapes. Cutting paths are generated for cutting the substantially uniform food product 12 into the digitally generated unique variation shapes 44. A control system 30 controls the operation of a cutting apparatus 22 cut the substantially uniform food product 12 along the generated cutting paths thereby portioning the substantially uniform food product into unique variations of naturally occurring food product shapes.

EDGE STABILITY
20220194029 · 2022-06-23 ·

A method and apparatus for cutting a Non-Crimp Fabric for improving edge stability and reducing stitch retraction is disclosed. The part of the NCF to be cut is treated with a binder and heated to activate the binder and therefore bind the tows and stitches together. By treating only the cutting path the drapability of the wider fabric is maintained. This may be achieved by heating only the part of the NCF to be cut, or applying binder to only the part of the NCF to be cut. The NCF may be compressed and cooled before cutting to improve binding action. A ply cutter may be adapted to carry out the invention by including a heat source and optionally a binder dispenser, compressor and cooler.
