KF-900S

A modern, fully programmable automatic unit for producing welt pockets and polo shirt plackets, delivering high productivity, repeatability and top-quality results.

The machine sews straight and slanted pockets, with one or two welts, with or without a flap. It can also make pockets with a zip and attach the pocket bag automatically. A further function is automatic sewing of polo shirt plackets, which considerably widens the machine’s range of uses in garment production.

A key element of the machine’s technology is the integrated laser system for cutting the pocket opening. The opening is cut before sewing, directly by a laser built into the machine head. Laser technology allows a pocket opening of any shape to be cut without changing mechanical parts such as knives, as traditional automatic pocket welting machines required. This increases production flexibility, shortens changeover time and ensures very high cutting precision.

In a single work cycle the machine stitches the pocket frame and sews reinforcing bartacks, giving the pocket a durable, neat finish. Depending on the configuration, the unit performs up to 8 operations fully automatically, such as:

• Material cutting
• Shaping
• Folding
• Sewing
• Bartacking
• Securing the pocket edges
• Attaching pocket bags
• Attaching pocket flaps

This considerably reduces production costs: there is no need to invest in additional machinery, and labour costs and operator wages fall. At the same time the whole production process becomes shorter, better organised and easier to control.

All operating parameters, including the pocket type and detailed process settings, are programmed on a clear control panel. The panel has a USB port for importing external data and transferring settings easily between machines. The machine’s memory stores up to 999 stitching patterns, which makes production management and quick changeovers much easier.

With its high level of automation, the machine combines several production stages in one process, so no additional operations are needed at other workstations. The unit can replace processes such as turning the pocket welts, bartacking and topstitching, which in traditional production need as many as three additional operators and several separate machines.

The machine works reliably on a wide range of materials, from lightweight shirting to heavier garment fabrics, giving a precise, neat pocket finish.
