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.

A cutting apparatus for sewing machines having a sewing zone including a presser foot and cooperating needle and a work surface on which workpieces are advanced to and beyond the sewing zone, said cutting apparatus comprising:
- (a) a cutting member supported on the machine downstream of the sewing zone;
- (b) a first actuating means for moving said cutting member between a raised position and one of operative association with the workpieces being advanced on the work surface;
- (c) a protective guard mounted on the machine in a manner to substantially surround said cutting member;
- (d) a second actuating means connected to said protective guard for moving the same between the positions travelled by said cutting member;
- and
- (e) means interconnecting said first and second actuating means for initiating movement of said protective guard to its position of operative association with the workpieces prior to movement of said cutting member thereto.
