发明名称 Apparatus for fitting shrunk on-foil hoods into recessed portions of a multi-layered stack
摘要 The opposite sides of the bottom layer of a multi-layered stack of packages have recessed portions. In apparatus for fitting a shrunk-on foil hood over the stack, a conveyor is positioned at a working station. The conveyor can be raised and lowered. After the stack is positioned at the working station, the conveyor is lowered and sets of rollers at each end of the conveyor are moved horizontally inwardly above the conveyor into the recessed portions of the stack. With the rollers within the recessed portions, the conveyor is lowered further so that the rollers contact the downwardly facing surface of the recessed portion. The relative movement of the sets of rollers and the conveyor permit the rollers to press the foil hood into closely fitting contact with the recessed portions of the stack. While the foil hood is pressed into the recessed portions, cooling air can be directed toward the stack to facilitate the shrinking action.
