Abstract
A flying paster is disclosed that achieves straight across splicing by utilizing web roll core drive technology. Splice calculations are based on input data sensed during preliminary acceleration of the new roll, which is disposed in a splicing position in the flying paster. Acceleration of the new roll is achieved by engagement between the center core shaft of a new roll and a movable brake and roll accelerator assembly. Then, calculations facilitate speed matching between the web running from a second, running roll mounted in the flying paster and the new roll. Splicing is facilitated by the utilization of two, two-sided adhesive strips. One adhesive strip is used to adhere the leading end of the new roll to the rest of the body of the new roll during the pre-splice speed matching, and the second adhesive strip is used for adhering the leading end of the new roll with the newly cut, trailing end of the running web. After splicing, the new, now-running web roll and the movable brake and roll accelerator assembly are moved from the splicing position to an operating position in the flying paster. In the latter position, control over the new, now-running roll is transferred from the …
