flexible material and then the film is sealed such wrapper modules are commercially available in a preferred embodiment of the present invention a wrapper module manufactured by c m c s p a graphic and mailing division of the ponti group of italy is used the overall wrapping system integrates this wrapper module with other modules to form a relatively large integrated combination system although some commercial wrapper units are capable of wrapping products at relatively high speeds and the speed may be varied the flow of products into and out of the wrapper needs to be carefully controlled and kept uniform because products are flowing at high speeds the wrapper may be u201c delicate u201d and gaps in the product flow can cause serious interruptions or other problems to develop at the wrapper 50 even if the wrapper is temporarily slowed down the purpose of the buffer 20 of the present invention is to close any gaps that might be present before the products are fed into the wrapper after exiting the wrapper the wrapped products are conveyed to a delivery wheel or pickup drum module 70 where they are removed from the wrapping system and passed to an overhead pickup conveyor 80 finally conveyor 80 transports the products away to other processing machines such as stackers or bundlers not shown fig2 is a perspective view of one embodiment of a buffer machine module.
