Device with a gripper for changing a bobbin thread spool of a sewing machine

摘要

The changing device (1) has an opening finger, which is linked to the bobbin case (3) in a spring-elastic manner for loosening a fixation on a middle pin. The gripper (2) has a lever (4) for lifting the opening finger of the bobbin case for clearing the fixation. The lever fixes the bobbin case by clamping against a chute in the gripper. A pin tap (6) is provided at the gripper for engaging in a recess (7) of the bobbin case.
