Automatic fabric cutting machine

01

Set the ply height and the vacuum hold-down

US patent 3,495,492 describes the hold-down principle behind automatic cloth cutters: a table, conveyor or drum with a porous bed through which a vacuum chamber draws air, applied zone by zone as the cutting or spreading tool travels along it, and a sheet of air-impervious material laid over the fabric so that the vacuum pulls it down and compresses the lay into a more rigid, compact state; the blade penetrates a resilient bed so that the lowest plies are cut cleanly, and the vacuum and film can hold a lay between spreading and cutting so that plies do not shift. [1]

A dealer listing for a Lectra Vector Q25 describes a low-ply cutter for small orders with a cutting height of up to 1 in (2.5 cm), an effective width of 72 in (1.83 m), blade cooling by compressed-air jet and a 22 kW vacuum booster for hold-down; Lectra itself describes the Vector Fashion range as cutting low to high fabric plies, with the Q2 and iX2 models for small orders, the iQ series for repetitive production and the iX series for high-volume work. [3] [2]

A dealer listing for a 2022 Gerber Paragon XR line gives a 2,200 mm cutting width, a maximum compressed material height of about 72 mm for multi-ply cutting, vacuum hold-down, real-time knife-deflection correction, automatic blade sharpening and a long vertical knife stroke, sold with a spreader of 220 mm maximum lay height and over 100 m/min spreading speed. [4]

Give the supplier the fabrics (woven, knit, stretch, coated; weight and thickness), order sizes and ply counts, required compressed lay height, fabric widths, marker lengths, pattern system and file formats, cutting accuracy and notching or drilling needs, daily output, spreading and offloading arrangement, floor space, power and compressed air, and dust and noise limits.

02

Set cutting speed, width and the cutting-room line

Lectra states that Vector Fashion cutting heads adapt to the actual fabric characteristics and reach cutting speeds of 8 m/min average perimetric speed, cut tangent and intricate parts with zero buffer between pieces to save material, carry hundreds of sensors for preventive-maintenance alerts and remote support with up to 98% uptime, use an energy-efficient turbine that reduces idling, and offer cutters for lingerie, denim and footwear. [2]

The Gerber patent places the cutter within an automatic line: spreading a lay of vertically stacked plies and cutting garment components from it under numerical or computer control. [1]

Editorial calculation: if the parts in a marker add up to 50 m of cut perimeter, a head averaging 8 m/min needs about 50 ÷ 8 ≈ 6.3 minutes per lay whatever the number of plies, so more plies per lay — within the cutter's compressed height — cut more parts per minute; check that ply count against the accuracy you need on the lowest plies. [2]

03

Compare cutter classes

Each row rests on one model or range: a Lectra Vector Q25 for low-ply, a Gerber Paragon XR line for high-ply, and Lectra's Vector Fashion series for the split by order size. [3] [4] [2]

05

Perimetric speed, compressed lay height and working width for a cutter order

Speed, compressed height and width carry published figures from single models; cutting accuracy has none, so ask for it on the top and bottom ply of your own lay. [2] [3] [4]
