For the turning of sewn ties members is used a tubular turning mandrel (8) to receive the tie member, and a gripping rod (16) with an outer gripping head (28, 30) is projected outwardly through the mandrel for gripping the outer end of the tie member and retracting the tie member through the mandrel. When gripped member end has been retracted therethrough the gripping system (16) is displaced laterally into a position in alignment with another mandrel (10), and a stationary clamp (38, 42) takes over the holding of the tie member end. The end portion (36) of the tie member thus bent-out is engaged by a smooth conveyor pin (48) causing the tie member to be folded rearwardly and causing the remainder of the tie member to be retracted through the mandrel with double velocity, concurrently with the gripping head (16, 28, 30) being actuated to grip a tie member on the other mandrel (10). The turning of the tie members can hereby take place with a high capacity. |
