A gripper arm, and a method for its manufacture, is provided for grasping, holding and guiding objects, for example, bottle-like containers. A rotatably mounted control cam may move a gripping section of the gripper arm from an open position into a gripping position. The gripper arm may have a bore hole for supporting a bearing pin for pivotably mounting the gripper arm, a seating for an opening structure for moving the gripping section of the gripper arm from the gripping position into the open position, and a suspension structure for cushioning and equalizing the force and deflection exerted on the gripper arm by the control cam. So that the gripper arm remains sufficiently free of contaminants and germs, the suspension structure may include a spring bar integrally formed in an end section of the gripper arm body.

1. A gripper arm for a device for grasping, holding and guiding bottle-like containers comprising: a rotatably mounted control cam for moving a gripping section of the gripper arm from an open position into a gripping position, having a bore hole for supporting a bearing pin for pivotably mounting the gripper arm in the device;a seating for an opening means for moving the gripping section of the gripper arm from the gripping position into the open position; anda suspension means for cushioning and equalizing the force or deflection exerted on the gripper arm by the control cam, whereinthe suspension means includes a spring bar integrally formed in an end section of the gripper arm body, wherein the end section includes a recess as spring space for the spring bar and forms a material limitation of the recess on its side of the spring bar facing the control cam, the material strength and material properties of which enable a cushioning and equalizing of the force or deflection exerted by the control cam on the gripper arm. 2. The gripper arm according to claim 1, in which the opening means to move the gripping section of the gripper arm from the gripping position into the open position is a magnet, and wherein the gripper arm includes a blind hole as the seating for the magnet in an anterior section between the bore hole and the gripping section, into which the magnet can be inserted during assembly of the gripper arm. 3. The gripper arm according to claim 2, wherein the magnet is encased in a plastic film. 4. The gripper arm according to claim 1, wherein the gripper arm is manufactured from plastic as one piece. 5. The gripper arm according to claim 4, wherein the plastic is fiber-reinforced polyether ether ketone. 6. The gripper arm according to claim 1, wherein the gripping section exhibits a tapering or stepped profile from an underside to an upper side of the gripper arm. 7. The gripper arm according to claim 1, wherein the gripper is a one-piece gripper arm and the suspension means that includes the spring bar is part of the one-piece gripper arm. 8. A method for manufacturing a gripper arm comprising: constructing a gripper arm for a device for grasping, holding and guiding bottle-like containers, the gripper arm having a rotatably mounted control cam for moving a gripping section of the gripper arm from an open position into a gripping position, and having a bore hole for supporting a bearing pin for pivotably mounting the gripper arm in the device; andforming a recess extending substantially in a longitudinal direction of the gripper arm in an end section of the gripper arm body, the recess's material limitation forming a spring bar that is integral to the gripper arm body, the spring bar disposed on a side of the recess facing the control cam, the material strength and material properties of the spring bar to enable a cushioning and equalizing of the force or deflection exerted by the control cam on the gripper arm while the transverse extension of the recess limited by the spring bar provides space for spring deflection of the spring bar. 9. The method for manufacturing a gripper arm according to claim 8, wherein the constructing further comprises: injection molding the gripper arm from plastic as one piece, wherein a blind hole is formed as a seating for a magnet in an anterior section between the bore hole and the gripping section into which the magnet is inserted to complete the gripper arm. 10. The method for manufacturing a gripper arm according to claim 9, further comprising: pressing the magnet into the blind hole. 11. A method for manufacturing a gripper arm comprising: constructing a gripper arm for a device for grasping, holding and guiding bottle-like containers, the gripper arm having a rotatably mounted control cam for moving a gripping section of the gripper arm from an open position into a gripping position, and having a bore hole for supporting a bearing pin for pivotably mounting the gripper arm in the device; andforming a recess extending substantially in a longitudinal direction of the gripper arm in an end section of the gripper arm body, the recess's material limitation forming a spring bar that is integral to the gripper arm body, the spring bar disposed on a side of the recess facing the control cam, the material strength and material properties of the spring bar to enable a cushioning and equalizing of the force or deflection exerted by the control cam on the gripper arm while the transverse extension of the recess limited by the spring bar provides space for spring deflection of the spring bar,wherein the gripper is a one-piece gripper arm. 12. The method for manufacturing a gripper arm according to claim 11, wherein the constructing further comprises: injection molding the gripper arm from plastic as one piece, wherein a blind hole is formed as a seating for a magnet in an anterior section between the bore hole and the gripping section into which the magnet is inserted to complete the gripper arm. 13. The method for manufacturing a gripper arm according to claim 12, further comprising: pressing the magnet into the blind hole.
