Abstract

The present invention relates to a procedure for optimizing the processing of cutting material, such as textiles, leather and technical fabrics and the like, as well as to a device to perform the procedure. The cutting patterns (T1, T2, T3) are first contained in the main memory of a computer (1) and then are selected. The selected patterns are projected on a cutting material on a working surface (AF) in their original size by means of direct laser projection, possibly with different colors, and are also projected on a control panel (4) in a scaled down size. The laser projections of the individual patterns are then interlocked on the cutting material by means of a control unit (5) actuated by an operator (P) positioned next to the cutting material. The patterns are interlocked to optimize use of the cutting material by accounting for the conditions of the cutting material, such as defective spots (F1, F2, F3, F4), and the shape of the cutting material. Once the patterns are finally positioned, data on these positions is then transmitted to a cutting unit, such as an automated cutter (C), by an instruction given by the operator and the citing operation is triggered.

Procedure for optimizing the processing of a cutting material (6), specifically for interlocking cutting patterns (T1, T2) before an automated cutting process by a cutting unit (C), by taking into account any defective spots (F1, F2) on the surface of said cutting material, said cutting patterns after having been set up in a computer system being stored as contours in a computer (1) from where the cutting patterns can be called and be positioned on said cutting material by means of a control unit (5) to a final position which is transmittable to said cutting unit (C), characterized by the following procedure steps:

i. selection of cutting patterns from the memory of said computer via said control unit by an operator positioned by said cutting material,
ii. direct projection of the contours of the selected cutting patterns by means of at least one laser on at least one optional spot and in any size on said cutting material,
iii. selection of specific contours from said selected cutting patterns and interlocking said contours on said cutting material by said operator and, when the selection and interlocking of said contours on said cutting material has been optimized, coordination of a cutting order for said cutting unit,
iv. triggering said cutting process by said control by the operator,
all processing steps on said cutting material being carried out directly by said operator and said cutting material not being moved until said cutting process is finished.
