ABSTRACT:
An automatic binding device or binder for binding a long material such as a bundle of electric wires with a lace by actuating the mechanisms associated therewtih according to pilot signals produced when the lace passes through the mechanisms. In this respect, a lace used should afford given rigidity and flexibility. This binder includes a guide member which may be opened and closed, and is formed with guide channels running along its inner peripheral surface for guiding a lace for use in binding. The guide member is formed with a lead-in hole for a lace on one side and a lead-out hole on the opposite side. For smooth guiding of a lace through guide channels, there is used a reversibly rotatable roller mechanism or a combination of the roller mechanism with a vibrating mechanism for vibrating a lace being guided through the guide channels. The lace paid out through the lead-out hole from the guide member is gripped by a lace gripping mechanism on the tip portion of the lace. According to a signal produced in association with the movement of the lace gripping and portion thereof, the primary tightening operation due to the reverse rotation of the roller mechanism is effected, followed by the secondary tightening operation due to the movement of the lace gripping mechanism. Thereafter, the lace is cut in the opposite portions of a knot or a bound portion thereof by means of cutters, and then waste lace thus cut off or chip is removed by suitable means.
