Methods and apparatuses discussed herein provide for localized speed changes of an advancing substrate (102). Embodiments of a localized speed varying apparatus may include first (110) and second substrate guides (112) positioned upstream and downstream of) a processing station (108), respectively. The substrate guides may utilize orbital motion of guide members (124, 154) to change the length of the substrate within the substrate guides upstream and downstream of the processing station. The changes in substrate length within the substrate guides result in localized speed changes of the substrate between the substrate guides. Coordination between the substrate guides allows for localized speed changes of the substrate passing through the processing station without affecting the speed of the substrate upstream of the first substrate guide and downstream of the second substrate guide.
La présente invention concerne des procédés et appareils pour changements de vitesse localisée d'un substrat en train d'avancer (102). Des modes de réalisation d'un appareil faisant varier la vitesse localisée peuvent comprendre un premier (110) et un second (112) guide de substrat positionnés en amont et en aval d'une station de traitement (108), respectivement. Les guides de substrat peuvent utiliser un mouvement orbital d'éléments guides (124, 154) pour changer la longueur du substrat dans les guides de substrat en amont et en aval de la station de traitement. Les changements de longueur de substrat dans les guides de substrat ont pour effet des changements de vitesse localisée du substrat entre les guides de substrat. Une coordination entre les guides de substrat permet des changements de vitesse localisée du substrat passant à travers la station de traitement sans affecter la vitesse du substrat en amont du premier guide de substrat et en aval du second guide de substrat.
