The cutting shop is the “heart” of any sewing enterprise. Any error in the laying of the canvas, inaccuracy of the cut or distortion of the warp thread during cutting is instantly multiplied into hundreds of units of finished products. In this industrial engineering guide, we'll explore modern cutting room protocols, from preparing rolls to synchronizing cuts with sewing flows.

Organization of the laying table and laying down the canvases
Before laying, knitted fabrics and elastic fabrics must be unwound from rolls and laid on racks for at least 12–24 hours to relieve mechanical tension.
Equipment: disc, vertical saber and belt cutting machines
The cutting of multilayer flooring (up to 50–100 layers) is carried out in stages: the flooring is divided into large blocks using a vertical saber knife, after which small parts are cut on a stationary belt cutting machine with an air cushion.
Minimizing inter-pattern lunges and calculating the laying coefficient
The optimal fabric utilization factor (FRU) in industrial cutting should be at least 85–90%. A competent combination of adjacent sizes in one layout saves up to 10–12% of linear meters of fabric.
Complete cut, numbering of packs and control of control notches
Each item in the pack is numbered with a label gun to eliminate color variations in the finished product. The depth of the control cuts should not exceed 3–4 mm, so as not to go beyond the overlock allowances.
Technologist's advice
The quality of cutting directly depends on the accuracy of the patterns. The use of proven electronic and cardboard patterns eliminates geometry errors. And you can download professional databases in the catalog ready-made patterns Vykroyka.com.ua.
Frequently asked questions (FAQ)
How long should a professional cutting table be?
For small and medium-sized workshops, the optimal length of the cutting table is 6–10 meters with a width of 1.8–2.0 meters.
How to prevent synthetic fabrics from caking when cutting with a knife?
Use Teflon-coated knives, an automatic blade lubrication system with silicone emulsion and adjust the cutting speed.
