Device for setting operation position of crimping hook in coin wrapping machine

Claim 1

In a coin wrapping machine of the type having coin wrapping means for wrapping a piece of wrapping paper around the cylindrical surface of each of successively arriving coin stacks each of a specific number of coins, the wrapping paper having a width greater than the length of the coin stack whereby lateral edges of the paper project outwardly beyond the ends of the coin stack, an edge fold crimping device including crimping hooks for fold crimping said projecting edges of the wrapping paper thereby to form a wrapped coin stack, and a wrapping paper storing device having a plurality of paper roll loading platforms for supporting thereon respective rolls of wrapping paper of respectively different widths corresponding to different heights of coin stacks and moving any of the platforms to a paper feeding position for unwinding and feeding the paper thereon to said coin wrapping means, a device for adjustably setting the operational position of at least one of the crimping hooks, said device comprising detection means for detecting the height of the paper roll on each loading platform, said detection means including a detection member undergoing a displacement in conformance with said height as detected by said detection mechanism, and a setting mechanism having a driven member engaged and driven by said detection member of a loading platform selected and moved to said paper feeding position thereby to set the operational position of said at least one crimping hook in conformance with the width of the wrapping paper on said loading platform.
