20080251352 | BUFFER FOR CLOSING GAPS IN PRODUCT FLOW, AND WRAPPING SYSTEM INCORPORATING SUCH BUFFER - A system receives flat products in a serial manner, transports them to a buffer apparatus, senses the presence of any significant gaps between adjacent products, passes the products to a wrapping or other processing machine and then removes the processed products from the system. The buffer closes gaps between adjacent products with an arrangement of fast and slower-moving chains or conveyors. | 10-16-2008 |
