An apparatus for stacking transparency frames, or other substantially flat articles, comprises a rotating cam body located between a feed-in arrangement and a receivng arrangement. The cam body is synchronized to the movement of the transparency frames on the feed-in arrangement, and guides the frames into a receiving shaft that forms a portion of the receiving arrangement. The rotating cam body provides continuous guidance to the transparency frames during movement between the feed-in and receiving arrangements. As a result, breakdowns during stacking are minimized. In one embodiment, the receiving arrangement is disposed transversely with respect to the feed-in arrangement. The cam body comprises a pair of cam discs having a circular sector configuraion. The arc length of the sector is synchronized to the spacing between the transparency frames on the feed-in arrangement. In a second embodiment, the feed-in arrangement and receiving arrangement are located in line to each other. The cam discs each contains receiving and reversing recesses that clamp an in-fed transparency frame. As the cam body is rotated, the frame is stacked in a position transverse to the direction of movement of the in-fed frames.
Apparatus for stacking substantially flat articles that are rigid at least in a region of the edges of the articles, comprising:
