ABSTRACT:
A machine which converts a strand of wire into a body of meandering shape has two carriers which rotate about parallel axes and respectively carry annuli of pins. One annulus of pins surrounds the other annulus of pins, and each pin of one annulus is adjacent to a pin of the other annulus. When the carriers rotate, neighboring pins of the two annuli move toward each other during one-half of each orbital movement about the respective axes and away from each other during the other half of each orbital movement. A looping device winds the wire alternately about the oncoming pins of the inner and outer annuli while the neighboring pins move away from each other whereby the wire is converted into a meandering body and the wire portions between successive pins are stretched to assume a predetermined shape. The meandering body is stripped off the pins while the neighboring pins move nearer to each other. The meandering body can be used as a starting material for binders which connect the sheets of note books, calendars or the like.
