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.

Improved Doctor Blades Offer Benefits
Flxon Inc.
, Charlotte, NC; 800/756-6474
Microflex II doctor blades for flexo and rotogravure printers offer new steel said to have more super-refined micro-particles than co.'s first-generation products. According to mfr., printers report faster seating, slower and more even edge wear, fewer streaks in print, and less anilox and cylinder damage.

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.

Improved Sheeter Now Faster, More Accurate
Maxson Automatic Machinery Co.
, Westerly, RI; 401/596-0162; maxsonautomatic.com
The MSL sheeter has a dual-motor AC servo drive system said to provide a 43% increase in speed, to 1,150 fpm (350 mpm). Co. says the AC electrical drive provides maximum torque. Can be upgraded to perform cut-to-register work. A microprocessor governs two encoders monitoring draw drum and knife cylinder. Microprocessor receives simultaneous signals from revolver's encoders, continually compares readings with each revolution, and directs drives accordingly. Process, notes mfr., increases accuracy by 65% to ñ0.015 in. (ñ0.38 mm).

Pouch Machine Features Servo-Actuated Sealing
Proven Designs Inc.
, Macedon, NY; 315/986-0909
Servo stand-up pouch machine produces reclosable stand-up pouches utilizing a single web construction, which reportedly reduces waste and downtime. Also can produce traditional two- and three-side-seal pouches with or without a reclosable feature. Offers servo-actuated sealing to reduce the number of air cylinders. Utilizes two independent servo systems for seal bar actuation: One system controls the cross-sealing section, and the other controls the longitudinal sealing section. This allows the bars to be timed separately, enabling optimization of sealing conditions for a variety of films, co. notes. Dwell time, sealing force, and cycle distance can be adjusted through the touchscreen interface.
