WESTERLY, RI | Maxson Automatic Machinery Co. offers a high-speed delivery system on its precision sheeters said to avoid marking sensitive materials when shingling the sheets. This design manages sheet flow by controlling the speed of the cut packet’s leading edge as it enters the overlap area, rather than nip pressure. The resulting action prevents stress marks from the stop roller and delivery belts while ensuring sheet packets are conveyed trouble-free to the stacker.
To permit high-speed sheeter operation, sheets are overlapped in the delivery system to arrest the forward momentum of the packet as it enters the stacker, thus avoiding damage to the leading edge of the sheet. Uniform contact across the sheeter eliminates sheet skewing, permitting higher speeds and enhancing pile quality.
The overlap roll carriage has an adjustment that allows the depth of the ringed roll to be set relative to the bottom slow-speed tapes. This variable nip setting eliminates the burnishing on sensitive sheets caused by excessive contact with the packet’s surface. The top high-speed tapes pass in between the rings of the overlap roll, removing the likelihood of belt marks.
