1. A web unwinding and splicing system comprising:
a turret unwind unit configured to hold a running web material roll and a new web material roll and to unwind a running web from the running web material roll, the running web having a web width less than a roll width of the running web material roll and being wound onto the running web material roll such that a transverse position of the running web on the running web material roll varies as the running web is unwound therefrom;
a web splicing unit operable with the turret unwind unit to selectively splice the running web of the running web material roll with a waiting web of the new web material roll; and
a web diverter unit including a web retaining assembly movable between a first position where the web retaining assembly is not in contact with the running web and a second position where the web retaining assembly is in contact with the running web;
wherein, with the web retaining assembly in the second position, the web retaining assembly temporarily holds the running web being unwound off of the running web material roll at a constant transverse position.
