Abstract
A folding device for an automatic sewing machine has a carrier plate for a first workpiece, a sword which is movable in the longitudinal direction thereof to receive a second workpiece and an outer frame having creasing devices for folding the second workpiece around the sword. The outer frame is pivotable into a total of three different working positions. In addition, it is movable out of its working positions into a retracted position. The purpose of this measure is to improve the field of vision for the operator while at the same time reducing the risk of an accident.

Folding device for an automatic sewing machine, comprising
- a carrier plate (32) for a first workpiece (37);
- a sword (80) attached to a sword carrier (76) for receiving a second workpiece (38);
- an outer frame (72) attached to an outer frame carrier (65) and having creasing devices (83) for folding the second workpiece (38) around the sword (80);
- a first working position of sword (80) on the carrier plate (32) and a second working position of the sword (80) in a vertical distance with respect to the carrier plate (32);
- means for causing relative motion between the carrier plate (32) and the sword (80) between said first working position and said second working position;
- a first working position of the outer frame (72) on the carrier plate (32), a second working position of the outer frame (72) which is substantially identical with the second working position of the sword (80) and above this second working position an upper work starting position of the outer frame (72);
- means for causing relative motion between the carrier plate (32) and the outer frame carrier (65) between the said working and work starting positions of the outer frame (72);
- and
- means for drawing out the sword (80) of one of its working positions into a retracted position out of the second workpiece (38);
- wherein
- means are provided for moving the outer frame (72) out of its working and work starting positions into a retracted position in the outer frame carrier (65).
