摘要 |
A rotary jaw closure unit (2) has one or more active elements (4). During an interval (- alpha 1; alpha 2) in which the active elements (4) of the rotary jaws (2) interact with a wrapping for products being wrapped to press it, weld it, and, possibly, cut it, the orbital speed of the jaws (2) is regulated to have a constant velocity. Jaw speed decreases linearly before the constant velocity interval and increases linearly afterwards. Electronic controller (10) receives a signal from an encoder (11) indicative of the rotary position of the jaws, and controls jaw motor (8) via control card (9). <IMAGE>
