Dual Rotary Shear Machine

SE1000 Dual Rotary Shear Machine

Product Description

The Shear can enhance the productivity of the entire line through reliable, high-speed
removal of scrap and looseback before it can enter the dry end. Unbounded board is a
frequent cause of dry end machinery jams. Shear features which allow excellent scrap out
reliability include:

Dual rotary design allows the shear to easily cut through all types of scrap
Driven diverter nip ensures positive diversion of defective sheets onto the scrap cart. This feature is essential to control board that is not cured properly
Exit brush prevents looseback accumulation around knife cylinders
Scrap cart moved closer to cutting cylinder to maximize scrap cart capacity and prevent sheet hang-ups during cart removal.

The Shear can enhance the productivity of the entire line through reliable, high-speed removal of scrap and loose back before it can enter the dry end. Unbounded board is a frequent cause of dry end machinery jams.

Product Features

Perfect for scrap removal or order change web severing. Low diverter angle improves divert reliability. Synchronized to order change control system. Dynamically balanced helical-wound blades on top and bottom knife cylinders.

Scrap Removal and order Change

The Rotary Shear design is like the Cut-Off Knife. The knife cylinders cleanly and squarely cut paper, singleface or any combination of board including triple wall.

Low diverter angle and divert reliability

A driven nip system ensures positive diversion of defective sheets onto the scrap cart. This feature works reliably at corrugator start up creep speed or at 300 mpm if a defective sheet must be removed.

Order Change Synchronization

At order change a single web sever at 300 mpm is possible. This web severed signal is used by the corrugator control system to initiate the order change. This can be timed to cut as a new paper grade reaches the Rotary Shear.

Dynamically balanced helical wound blades

This design allows the shear to easily cut at speeds up to 350 mpm for the 2500 mm machine width and 300 mpm for the 2850 mm machine width.

Shear	Sever Web	Divert
2500mm (98,4")	350mpm (1150fpm)	300mpm (1000fpm)
2850mm (112")	300mpm (1000fpm)	260mpm (850fpm)

Low diverter angle improves divert reliability
Scrap cart can be easily emptied with fork truck.
Parts interchangeable with MarquipWardUnited cutoff knife (knife blades, cylinder motor, and drive).
AB CompactLogix PLC Controls Platform.
New frame positions scrap cart upstream for improved scrap stacking and unobstructed cart removal.
Divert Nip enhances scrap handling.
Helical-wound blades on top and bottom knife cylinders produce a square cut. This allows the user to make a sellable first sheet on every order change without the waste of a first trim cut. This decreases waste, and keeps small scrap sheets out of the dry end. It also allows for square dunnage sheets when needed.

Remote Scrap Divert - wet end operator selection of length to be diverted
Automatic Dry Spot / Hot Plate Scrap Divert
Splice Detect and Automatic Divert
Adjustable Sheet Length - variable cut length capability allows operator to select a shear
cut length for diverted sheets between 787 mm (31鈥�) and 1549 mm (61鈥�)
