The reject gate on MAXSON Sheeters is capable of diverting one or any number of successive sheets at speeds of up to 300 cuts per minute. This assembly utilizes sensors to time the directional flow of sheets cut and the starting and stopping of the slow speed tape system.
When the rejection system is activated, a directional gate alters the flow of sheet to a Customer supplied bin. Through the drive arrangement, the slow speed tape system is stopped; positioning the last acceptable sheet cut on the slow speed tapes. This feature eliminates potential jam-ups at the overlap section when the flow of the sheets is resumed to the stacker, by insuring the oncoming sheet’s leading edge positively overlaps the trailing edge of the last acceptable sheet.
To insure positive rejection of sheets and protect the overlapping delivery tapes, the reject gate is formed to allow its “fingers” to divert rejected sheets while allowing the high speed tape section’s tapes to pass between the manifold.
Operator controls for the reject gate are mounted at the cutter in feed station and at the main operator console. The reject gate can also be automatically initiated by a splice detector or web inspection system.
