Daco PLR250 / 350 / 430 Semi Automatic Turret Rewinder

The Daco PLR 3 spindle semi-automatic turret rewinder offers all the benefits of turret rewinding but with very quick make ready 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 whilst operators cut and re-apply the web to the cores, the PLR semi-automatic turret is only stopped for a few seconds whilst the turret indexes.  New cores are applied to the rewind shaft whilst 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 (16.92″)
