Patent ID: 7938925

Claim:
A method for bringing a new roll of paper web material from zero to corrugator operating speed in a corrugator splicer after effecting a zero speed splice, wherein the splicer includes a dancer roll system located at the downstream output end of the splicer and a motor-driven capstan roll assembly comprising a capstan roll driven by a motor located between a splice sealing apparatus of the splicer and the dancer roll assembly, the capstan roll assembly adapted to apply supplemental tension in the web between the capstan roll assembly and the newly spliced in paper web material, causing the paper roll to accelerate until the paper web unwinding from the spliced-in paper roll achieves corrugator operating speed, the method comprising the steps of: applying a driving torque to the capstan roll assembly with driving torque to start at an initial level of torque near zero and to increase over a short time period in the range of about 2 to 3 seconds up to a maximum driving torque level achieved when the capstan roll slips beneath the paper web; and achieving an increasing tension in the paper web between the capstan roll and the newly spliced-in paper roll during the short time period that reduces jerk on the paper web and prevents web tear out while accelerating the paper roll until the paper web unwinding from the roll reaches corrugator speed.
