Before you choose
Questions about this machine.
Is this one fixed configuration for every garment?
No. Share the garment sizes, fabric stretch, seam construction and production layout. Templates, handling and working-area options must be confirmed for the intended operation.
What space should I reserve?
The catalogue provides separate packing dimensions for the three units, not a complete installed floor plan. Request an installation layout and utility plan for the quoted configuration.
How should I evaluate a sewing automation workstation?
Describe the complete sequence: component loading, serging, transfer, hemming and collection. Send the garment and template information together with current handling requirements. Any output target must be assessed against the actual configured workflow.
