Abstract: Needle gripper features a gripper unit with a gripping surface facing a workpiece to grip, and a needle carriage with a gripping needle. The needle carriage moves into an active position extending the gripping needle beyond the gripping surface by one needle stroke depth, and in a passive position retracting the gripping needle, and features a drive unit with a drive actuator driven forward/backward along a drive direction that couples to the needle carriage so it moves into the passive/active positions by driving the drive actuator forward/backward. A setting device for setting the needle stroke depth includes a guide carriage displaceable perpendicularly to the drive direction along a guide direction, and a stop for the guide carriage. The drive actuator couples via connection arm to the guide carriage so when the drive actuator moves backward, the guide carriage moves in the direction toward the stop, which prevents further backwards movement.

Abstract: Needle gripper comprising a gripper unit with a gripping surface (20) facing the workpiece to be gripped, and at least one needle carriage (32) with at least one gripping needle (22), wherein the at least one needle carriage can be displaced into an active position in which the gripping needle is extended beyond the gripping surface by one needle stroke depth (24), and in a passive position in which the gripping needle is retracted, and comprising a drive unit with a drive actuator (26) which can be driven forward and backward along a drive direction, wherein the drive actuator is movably coupled to the needle carriage so that the needle carriage can be moved into the passive position and into the active position by driving the drive actuator forward and backward, and with a setting device (34) for setting the needle stroke depth, which comprises a guide carriage (38) which can be displaced perpendicularly to the drive direction along a guide direction (36), and a stop (54) for the guide carriage, wherein the
