Straight answers from the engineers at Golden Tec Machinery Co., Ltd., a sheeter maker in Taichung, Taiwan since 2000.
A rotary sheeter is a machine that cuts paper, board or film from a reel into flat sheets using a rotating knife. The web is unwound, flattened, slit to width, cut to length by the rotary knife, then overlapped and stacked into piles ready for printing or converting.
A single rotary sheeter cuts with one rotating knife against a fixed bed knife; a synchro rotary sheeter uses two knives rotating in sync, which gives a cleaner, quieter cut on heavy board. At Golden Tec the single rotary TKSC covers 60–550 gsm at ±0.5 mm, and the synchro TW covers 120–650 gsm at ±0.3 mm.
Choose by the heaviest material you will cut. Up to 550 gsm, a single rotary sheeter such as the TKSC is usually enough; from 550 to 650 gsm, or when you need ±0.3 mm, choose a synchro rotary sheeter such as the TW. Above 650 gsm, send your specification for a custom check.
Multi-web sheeting cuts several reels at the same time, stacked on top of each other, to multiply output on light papers. The Golden Tec TNSC cuts multiple webs up to 500 gsm total, giving 4, 6 or more times the output of a single web.
A cut-to-register sheeter reads a print mark on a pre-printed reel and cuts each sheet exactly on that mark, so the print lands in the same position on every sheet. Golden Tec's cut-to-register option (RGT) cuts to register at ±0.3 mm on its single-web TKSC, TW, GTM and CSZ lines, for labels, paper-cup stock and printed packaging.
Cut-off accuracy on Golden Tec sheeters is ±0.5 mm on the single rotary lines and ±0.3 mm on the synchro TW.
Standard frames take reels up to 1,400 mm (55") or 1,700 mm (67") wide. For wider reels, send your specification and an engineer will check feasibility.
Send the material type, basis-weight range (gsm), reel width and diameter, the sheet sizes you cut, and your monthly volume. With these, an engineer can recommend a configuration and price it.
Golden Tec Machinery Co., Ltd. (金益興機械) designs, assembles and tests its rotary sheeters in Taichung, Taiwan, and has built sheeters since 2000.
