Beschreibung
Zusammenfassung:	A cell film breaking apparatus is used for breaking cell films of foamed products to change independent formed cells to continuous cells of the foamed products. The apparatus includes a conveyor for transferring the foamed products through the apparatus, a frame arranged above the conveyor to be raised and lowered relative to the conveyor by means of a reciprocating device, a plurality of pressing devices mounted on the frame and arranged in rows to be urged upward relative to the frame, cams arranged corresponding to the pressing devices to drive the pressing devices downward, respectively, and rotating driving device for rotating the cams in synchronism with each other. With this arrangement of the apparatus, all cell films of foamed products can be broken without omission at a high ratio of broken cell films to unbroken cell films with less man-hours.
