    • A system for applying a heat-shrinkable sleeve or label to a container such as a vial for pharmaceuticals includes a novel heat tunnel assembly. The heat tunnel assembly, in a preferred embodiment, includes a conveyor for moving the sleeved containers past a heat source. The conveyor has a plurality of rollers upon which the sleeved containers are supported and rotated. The rollers turn at a first rate during initial shrinkage of the sleeve, and at a second, slower, rate after the initial shrinkage has occurred to reduce distortion and unwanted displacement of the label during its application. The heat tunnel assembly also includes a system for withdrawing the heat source from the vicinity of the conveyor should unexpected circumstances arise.
    • 将热收缩套管或标签施加到诸如用于药物的小瓶的容器的系统包括新颖的热隧道组件。 在优选实施例中,热隧道组件包括用于使套筒容器移动通过热源的输送机。 输送机具有多个辊子,套筒容器在该辊上被支撑和旋转。 在初始收缩发生之后,辊子在初始收缩期间以第一速率转动,并且在第二次较慢的速率下转动,以减少标签在其应用期间的变形和不想要的位移。 热隧道组件还包括一个系统,用于在出现意想不到的情况时从热交换器的附近退出热源。
