Co. introduces a patented new inflation toggle valve COR-LOK® airshaft option—TVCLAS—that is said to help reduce roll changeover times. TVCLAS employs standard rotary union for pneumatic hook-up and is specifically engineered for use in cantilevered applications. It is available in COR-LOK airshafts in 2 to 18 in. diameters. The main advantage of the TVCLAS is that it facilitates rapid roll changeovers. Because the easily reached toggle valve is built into the end of the airshaft, an operator does not have to leave the station to access a remote inflation control or retrieve any tools. The TVCLAS airshaft system is also compatible with CAC's sleeve-based core adapting option that allows converters to run varying core sizes, both 3 and 6 in. for example, on the same shaft or air shaft.

Co. offers safety chucks that slide open with a patented push-button mechanism. Because they open only in the upright position, roll security is guaranteed. The sliding action reduces finger-jamming accidents common with tilting models. Chucks can be flange-mounted or foot-mounted, fixed or with sidelay adjustment. Sidelay adjustment models allow accurate roll positioning with an easy-to-operate handwheel, with horizontal range up to 4 in., reports co. Unique options of Double E chucks include fixed drive shafts, swivel bases to correct baggy web edges, and air operation.
