Paper unwinder

These days, corrugators need greater and greater flexibility. Shorter orders and frequent quality changes often limit the corrugator’s productivity and place an increasing burden on operating personnel. When it comes to minimizing speed reductions, the ability to load paper simply and quickly is of great importance. The robust construction of BHS Corrugated’s Reel Stand and the highly precise parallel positioning of paper rolls make for optimum smoothness even at maximum speeds of up to 750 m/min. The backlash-free wedge guide between the support arms and the support shaft enables precise adjustment of the arms. This guarantees that the paper roll is unwound without any creases. Hydraulic cylinders lift the paper rolls with maximum reliability and precision. The advantage of the mechanical expansion cones is that they allow the sleeves to be securely fastened. Powerful, ventilated disc brakes ensure adequate braking performance and constant web tension in every speed range – the key requirements for optimal operation. With fully automatic roll loading, the Reel Stand is equipped with sensors to allow work processes to run safely and smoothly. In this version of the Reel Stand, the center of the new paper roll is automatically adjusted to the center of the paper roll which is still in operation. As a result, the paper webs are precisely aligned with one another, and (manual) roll alignment after splicing is no longer necessary. The rest of the roll or sleeve is removed after splicing without any further manual intervention.
