Daco PLR250 / 350 / 430 Semi Automatic Turret Rewinder
PLR Semi automatic turret rewinder for the fast efficient rewinding of self adhesive labels with a web width of 250mm (10″), 350mm (13.75″) and 430mm (17"). - (UK Patent Number GB2584200)
The Daco PLR 3 spindle semi-automatic turret rewinder offers all the benefits of turret rewinding but with speedy makeready times, unlike conventional turret rewinders. This allows shorter runs to be produced both quickly and more efficiently.
Unlike traditional inspection slitter rewinders, where the machine is stopped for a considerable time while operators cut and re-apply the web to the cores, the PLR semi-automatic turret rewinder is only stopped for a few seconds while the turret indexes. New cores are applied to the rewind shaft while the machine is in production, the turret automatically cuts and applies the web to the new cores.
If further automation is required the Daco SVT fully automatic turret rewinder which is a servo-driven offline turret rewinder with label closure which increases productivity further.
Web width 250mm (10″), 350mm (13.75″) or 430mm (17″)
