Fulton, N.Y.-based Black Clawson Converting Machinery LLC is marketing an easy-thread winder and roll changer, dubbed the EZT winder, to makers of oriented film.
The closed-loop pressure roll system, which incorporates Black Clawson's nip control system, winds PET, bioriented polypropylene, polystyrene and other oriented films with enough nip to produce a tight roll, without deforming the web over the caliper band areas across the roll.
A roll changer opens up to give a straight threading path through the web, providing continuous winding.
Other EZT winder features include patented, dual-direction, stationary knife technology, for full reliability of making a straight line, no fold-back transfers to the new core at any speed and a precision dancer with “shock-absorbing” capability on the slack takeup after a break in the web.
In business news, Black Clawson has commissioned a new cast stretch film line for Perfiles de Plastico Flexibles SA de CV in Naucalpan, Mexico. The machine can produce more than 31,000 pounds a day of five-layer polyethylene stretch film, at 1,500 feet per minute at a finished width of 86 inches. The line has four extruders and a flat die from Extrusion Dies Inc.
