Abstract
A twist tie device for twisting together the ends of the tie ribbon and encircling an article which is positioned therein for tying is provided. The device includes a feed element for feeding the tie ribbon in the device to the article. An arm is provided for guilding the tie ribbon around the article. A twist head, connected to a rod, is provided for tightening the tie ribbon around the article. A gear assembly is provided for rotating and driving the twist head and for driving tie ribbon feed element. A cylinder with a rod plunger, forming an actuator, is coupled to the gear assembly. In response to a control signal, the actuator moves in a first direction between a start position, a first position and a second position. When the actuator moves from a start position to a first position, it makes contact with the arm so that the arm partially wraps the tie ribbon around the article. The actuator then moves to a second position and drives the gear assembly so that the twist head tightens the tie ribbon around the article. The actuator then returns to a start position driving the gearing assembly to feed the ribbon in the device for a next twisting cycle. The twist tie device is eas…
