Daco Si350 Label inspection rewinder with waste rewind & missing label detection


The Daco SI350 / 430 label inspection rewinder / slitter rewinder offers both flexibility and high performance. The unique design of this inspection rewinder includes a quick make ready rotary scissor slitting unit with knife separation and lateral adjustment. A touch screen HMI operator interface enables quick and easy job setups, control of the various counting facilities, automatic web advance, taper tension control and end of roll features.

The machines unwind and rewind has taper tension control as standard which enables the tension to be kept at a predetermined tension set by the operator. Adjustment of the tension in relation to the roll diameters is automatically compensated for by the PLC.

A BST electronic web guidance system ensures that the finished rolls are perfectly wound and an inspection table with adjustable splicing table with pneumatic clamps is also fitted as standard, enabling splices to be made both neatly and easily.

Pneumatic airshafts for both unwind and rewind ensures simple roll changes and a web advance system makes it simple to attach the web to the core when starting a new roll.
