Abstract: A web unwinding and splicing system includes a turret unwind having a turret arm with rotatable shafts at opposing ends thereof to unwind a running web of an expiring web material roll and unwind a waiting web of a new web material roll. A web splicing unit operable with the turret unwind includes a web deflection device that bumps the running web onto the waiting web to splice the running web with the waiting web and a cutting device that selectively severs the running web, thereby creating a leading portion of the running web that is spliced to the waiting web and a trailing portion of the running web that remains separate from the waiting web. A vacuum system is positioned proximate the running web to suction in the trailing portion of the running web left on the expiring web material roll.
