ABSTRACT:
The invention pertains to a cutting apparatus for sewing machines disposed downstream of the machine's sewing zone. The apparatus includes a cutting blade and a protective guard for the blade both of which have independent actuating devices. The actuating devices are effective in moving the guard and blade between one position which provides clearance for the workpieces being advanced along the machine's work surface and another position where they are operatively associated with the workpieces. A timing element is operatively associated with both actuating devices and is effective in causing the protective guard to be moved toward the workpieces prior to movement of the blade.
