Traditional mechanical tail cutters typically use rotary saws or fixed blades. With the blade in direct contact with the sheet, oscillations become their greatest enemy, making them difficult to operate on fast, higher-oscillation machines.

A mechanical tail cutter requires a well-dried sheet to cut without ripping it, which creates delays before thread-up after a cold start. The blades need to be replaced often, especially on more abrasive papers. Blades and saws are not recommended for fast machines, where the combination of a dulling blade and sheet oscillation can lead to sheet breaks when threading up. Finally, the blades and saws’ cut quality tends to be bad when the sheet flutters.

The Jet-X™ 2000 is an automated, single-cut high-pressure water-jet dry-end tail cutter with precise tail width capability for pulp, paper and tissue grades.

The Jet-X™ 4000 is an automated, dual-cut high-pressure water-jet dry-end tail cutter providing precise tail width and positioning capability for pulp and paper grades. The process initiates with the tail being moved quickly away from the tending side edge for optimal threading while progressively widening to take the draws. The sheet can be widened from the center, subsequently resulting in symmetrical reel spool starts.
