Abstract
A binding apparatus in which an adhesive tape is wound several times around an article to be bound, thereby binding the article. The binding apparatus includes a rotary table having a bobbin rotatably retained thereon, an adhesive tape feeding device for winding a given length of an adhesive tape around the bobbin, and a driving device for rotating the rotary table. The rotary table is rotated around the article to be bound by means of the driving device so that the adhesive tape wound around the bobbin on the rotary table is wound around the article to be bound.
Claims8
A binding apparatus comprising:
- (a) a table having a central axis, a circumferential periphery, and a groove extending from said circumferential periphery to the center of said table, said groove being sized, shaped, and positioned to permit an object to be bound to be moved from an external ready position to a work position in which the object is located on said central axis of said table and said table can rotate around the object and from the work position to an external finished position;
- (b) first means for conveying an object to be bound from the external ready position to the work position and from the work position to the external finished position;
- (c) second means for rotating said table in either direction;
- (d) a bobbin mounted on a first side of said table in parallel to but offset from said central axis of said table;
- and
- (e) third means for attaching a first end of an adhesive tape to said bobbin, for wrapping the adhesive tape around said bobbin a predetermined number of times, for cutting the adhesive tape to form a second end of a piece of adhesive tape sufficient in length to pass several times around the object to be bound, for positioning the portion of the piece of adhesive tape between said bobbin and the second end of the adhesive tape so that said portion is at least approximately parallel to said first side of said table and so that said portion passes over said groove at least approximately transversely to said groove, for gripping the second end of the adhesive tape while said first means conveys an object to be bound from the external ready position to the work position, during which motion the object strikes the portion of the adhesive tape between said bobbin and the second end of the adhesive tape, and for releasing the second end of the adhesive tape before said second means rotates said table several times, thereby unwinding the piece of adhesive tape from said bobbin and winding the piece of adhesive tape around the object to be bound.
