BINDING DEVICE WITH IMPROVED TWISTING HEAD AND BINDER EQUIPPED WITH SUCH DEVICES, IN PARTICULAR FOR BINDING COILS OF WIRE

摘要

A binding device is provided for placing a flexible bond (F) around an article to be bound. The binding device includes guide members (10, 11) for bringing two opposed end lengths of the flexible bond to cross over each other, and a head (32) placed at the rear of the guide members for twisting the end lengths. The head includes a gripper (32a) mounted on the end of a rotary body (33). A threaded portion (41) of the body (33) of the twisting head (32) is threadedly engaged in a nut (42) integral with the frame. A coupling member (44) surrounds a portion of the body (33) such that the body (33) is slidingly mounted in the coupling member (44). Rotation of the coupling member achieves the rotational driving of the body of the twisting head and simultaneously permits a continuous axially advancement of the body of the twisting head due to the threaded engagement of the body with the nut.
