Differential Shaft Speeds Production
Ashe Converting Equipment
, Ipswich, U.K.; +44-1-473-710-912; ashe.co.uk
The ADS differential shaft is designed to enhance the performance of co.'s Sapphire, Emerald, and Solitaire slitter/rewinders. The shaft reportedly allows converters to speed production by slitting and finishing more rolls with varying widths. It can exert equal torque along its length at any time, so it can hold a number of cores with varying widths in one operation, mfr. says, adding that this allows converters to produce a variety of finished rolls off the same master while the material is being wound in-line. Said to be well-suited to low-tension winding for demanding products, but not exclusively, as it can switch unused elements off on command.

Knife Holder Helps Blade Last Longer
Dienes Corp.
, Spencer, MA; 800/345-4038; dienescorp.com
The Cushioned Side-Load Head uses a cushion of air to remove the spring effect said to be common to side-loaded blades in shear slitting. This reportedly encourages longer blade life in several ways: It dampens the actuation of the top blade; keeps force equally distributed along the entire length of the blade; and minimizes side-load force, making less cutting force necessary.
