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.

Winding machine with device for calculating the poisson's ratio and related method

The machine (1;100) comprises a winding station (3; 101), adapted to receive secondary winding cores (T) coaxial with, and adjacent to, one another. The machine further comprises a cutting device (11; 104) with a plurality of blades (13; 105), arranged upstream of the winding station (3; 101) with respect to the feeding direction of the web material (N) and adapted to slit the web material into a plurality of strips (S1-S5) of web material.
