摘要：A wrapping device comprises a free wheeling film roll mounted on a frame, a film withdrawal slot to guide the film exterior of the frame, a detector to detect the withdrawn film length, a comparator which produces a locker signal each time when the film withdrawn accords with a predetermined length of the film by means of detector signal from the detector, a locker structure for locking the roll in the film withdrawal direction by means of the locker signal, and a press roller to seal the film about a wrapped goods-laden tray. The film on the roll is prevented from being unnecessarily withdrawn and thus allows and economical use of the film.
