Precise knife and core positioning is an important aspect of setting up an Elite Cameron paper converting machine. Minimum deflection and rigidity are essential qualities of the linear motion system that carries the precision measurement device and laser source - any deflection in the shaft would compromise slitting accuracy. Manufactured by Somerset based T S Converting, the Elite Cameron's slitting system positioning arrangement is provided by a HepcoMotion SBM GV3 slide with integral supports. For T S Converting, this integrated unit offered the most cost effective option, being versatile in mounting yet strong enough to withstand any misuse.
The slide used in this particular application is double-edged and the carriage plate on which the measuring instruments are mounted is moved manually. The load on the carriage is less than 1kg, and while smooth movement is essential, some friction is required to prevent the carriage from over-running as well as giving the operator a degree of 'feel' during the knife alignment procedure. For this purpose, the linear system bearings were supplied pre-loaded. It was also fitted with cap wipers that, in addition to introducing an element of friction, keep the guide-way free from any paper dust ingress.
According to T S Converting design engineer, Rob Snell, the supported unit was easy to install and has proven to be simple to service. Although the fundamental operation of the knife and core positioning system remains the same, it is packaged by the company to fit different machines. It therefore specifies HepcoMotion SBM in a variety of sizes to meet these needs.
