Maxson's reject gate assures high speed jam free sorting

Press release from the issuing company

Westerly, RI USA - Maxson Automatic Machinery Company outfits its high speed precision sheeters with a sophisticated reject gate design that makes certain that defective sheets are separated trouble free from acceptable product at speeds up to 1300 fpm (396 mpm) even on light weight materials.

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 movement of the tape system. When the rejection system is activated, a direction gate alters the flow of sheet to a Customer supplied bin.  Through a 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.  Operator controls for the reject gate are mounted at the cutter infeed station and at the main operator console.  The reject gate can also be automatically initiated by a splice detector or web inspection system.
